Yeah but if your idea of an ideal subwoofer is one that booms the loudest and rattles the most nearby car windows at the stoplight, you definitely want a ported system.
My SEALED house speakers generate far more Vibrational bass, than my Ported speakers. The Port does not change make the speakers any more powerful. The Magnet strength, Coil strength, are what create the strongest potentials. The Subs shown here, are not for Car Audio. They are for home theatre, and possibly also to add depth to music. Unless you live in the middle of the country... you cant blast High Air Pressure Subs, in a typical apartment. Furthermore, Its Immoral, to blast Car Subs in the City. People live in the apartments above the storefronts... and it Ruins these peoples Sanity, and Lives. It also ends up dragging down property values... when the local Drug dealer parks their car, and keeps blasting their sub, at 3am. Keep pushing people like myself... and you will find out, just what can happen...
You forgot to mention the fourth type of sub. The douchebag. The DB comments unnecessarily on videos that aren't discussing the subject they think it is.
"slot loaded" (not resonant tuned like altec and ATC ports), isobarik, transmission line, open baffle, and varovents exist too. the frequency response of passive radiators is more peaky
Kudos to this guy. He gives concise yet simple enough explanations for normal people to understand the technicalities of the convoluted hi-fi world and presents it in a very entertaining manner.
That's the most comprehensive explanation of the differences or ported and sealed I've seen, and easy to understand the pros and cons of each. Great video!
Been designing speakers for many years and speakers have changed a lot. Some are best in ported and some sealed according to the speakers parameters. Personally I will take properly designed ported sub over a sealed box. It's all in how much you spend and how good the box design is but really it's all about personal preference in he end.
How would you determine if a chassis ist best for sealed or ported? I've read that if fs/Qts is around 50, it's best for sealed while a value around 100 is best for ported. What do you think about that?
@@doemaeries This is called EBP and it's a good starting point but you can still make a high EBP driver work, the box size might just not be optimal. If you already have the driver you can make it work you just need to model it and see what you're in for. If you don't have the driver yet it would be best to buy the driver to fit the style of box you want to build.
Ported for Home Theater. Sealed for music. POrted is going to give you that steady deep rumble when the jet liner goes across your screen. Sealed is going to give you that tighter, less boomy sound for music. I have 2 HSU VTF-2 MK5's used for 95% home theater.
Ported Is mainly made for and sold by musicians. A frequently purchased subwoofer is, for example, the Yamaha HS8S and JBL LSR310S. Then a ported turns out to be better 🤔
This is a really good video. Well done. You saved me from worrying and wasting time about something I don't need to worry about. Sealed sub in my car for me! Thanks!
This is not always true ive had both sealed and ported i promise you if you put a dual or single skar sdr 12 in your care you will be so much more happy than with sealed ive had and used both and I still have one bc it gets deeper sounds better and it still articulate and musical but loud you don't have to give it all 1200 watts if u dont want put it at the volume you like
In my personal opinion both sealed and ported are in the past but less ported than sealed because passive radiators are a perfect balance you get deeper and louder than sealed and just as small without having to worry about port noise
@@valorantorion1588 Car subs with passive radiators have had their niche for a long time but never really picked up. Why do you think that is the case? No, they're not the same size as sealed boxes and they have almost exactly the same problems as basreflex subs. The car audio market is dominated by basreflex subs because they're so efficient and people want to install as few extra batteries as possible. It's as simple as that. Maybe electric cars will change that.
Ported enclosures are far superior but the trade off is that they're way more expensive and need more space, specially if you want a well made box. But I ported enclosure will be way louder than a sealed enclosure and will be more efficient. If you like loud bass, 100% vented.
For the whole video i kept thinking that the presenter will show both sub woofers performance effect on that box filled with water... 😆 🤣 how many agree?
I've always preferred sealed. I also like just ten inch subs for the much tighter quick hard hitting bass they reproduce. Though in my huge roomy 85 GMC Suburban, just wide open no trunk, bass lacked in that wide open environment. The same amp/sealed box/speakers in my Ford Tarus was much more pronounced sitting in the trunk then in the Suburban. The type, how they are arranged, the box and the amp can really make a huge difference depending on the setting they are placed into trying to get the sound you are looking for.
Oddly enough, Ford used the trunk space in the Taurus to be a 'box' to help with bass. There were two 6x8 speakers in the rear shelf standard but there was also a spot for a 6x9 speaker that was meant to be used with the JBL systems that were optional on those cars. I didn't have the JBL system in my Taurus, just the MACH audio, but with some work I managed to add a line driver before the main MACH amp. The line driver had a subwoofer line out which I ran to a small (300 watt) sub amp and a 6x9 speaker I added in the rear shelf. I didn't have it loud but it added quite a bit of low end bump. Depending on what I was listening too the inside of the car would shake at a moderate volume. I miss that car and the system (I kept the components.) The factory Sony system in my Fiesta just can't compare.
A good sub of any size can produce punchy bass. I have three 21 inch subs in my theater that can reproduce anything from 15Hz to 200Hz with no problem. When you go to a concert and hear the quick drum bass it is from ported 15 or 18 inch subs, just for reference.
a Ported subwoofer box is better it has a pipe organ effect and pushes air better you won't get good bass with a sealed box I have had both and ported subwoofer boxes sound much better now I will say this ported boxes have a negative side They can stretch the subwoofer and damage It by sucking air into the box if played at to high of volume now Down to the sealed box they are good for not stretching out the subwoofer but have a negative side also they over heat the subwoofer because they are not ported so they don't air cool the subwoofer
Well, the ported speaker can move around the tuning frequency a lot of air with very little movement, which brings many benefits compared to a sealed speaker, including the overheating. Still, the sealed speaker will always have certain advantages on it's side. At the end, it should be just a matter of taste which speaker you might choose for yourself. Doesn't make sense to get in heat about it.
I honestly like ported subs. My mom has one and I just love the way the bass is so deep. I never liked the full, movie theater type of sound with low frequencies.
@@d3vi0uz1 Just Checked that out. Looks like some do, and some dont. It seems The sub frequencies from your speakers are mostly dependent on your environment.
I have the Kanto Yumi set up with the Sub 8 and it sounds great the 8 sounds as good and goes lower than my mb quart 10 in. I do find it moves on me on a smooth surface. Great video
So, with all these trade-offs, how about someone designing a two driver system, with one sub ported and the other sealed, each isolated from each other, but in the same enclosure. I'm not an audiophile, I'm more of a melomaniac, so maybe this is a stupid idea, but I tend to try to "think outside the box ".
As a fellow melomaniac, I like your line of thinking on this subject. Maybe one the highly trained audiophiles can explain why this isn't practiced. Sounds like a good idea to me.
I used to always automatically go for large ported subs. It seemed common sense they would dig deeper and be better for movies. This all changed when I was gifted a small little Martin Logan Dynamo 10" sealed sub. It utterly destroyed my SVS. It plays clean to the low 20s and also has really tight punchy bass. Best of both worlds and I've never owned a ported sub that did both of these things well. Was blown away by that little ML sub.
@@benboyer2776- design and quality components matter. That Martin Logan was probably much more expensive too. I went from a huge 400w sub to a REL (T2) 10” with passive radiator that was better at basically everything. Music and movies. It was more $$$ of course.
not exactly... passive radiators have uneven frequency responses. If you want more QUANTITY out of sealed... just add more power + EQ or drivers. I DESPISE boomy flabby bass. The first time bass wowed me was infinity 4 1/2" 2 ways! the bass was soooo tight and fast, if not chest thumping. I'll take quality every time
Thanks for this explanation! In building custom boxes for my truck I noticed when I added ports as I was meant to I lost clarity, this clearly tells me that what I want is a sealed box 👍
A passive radiator essentially mimics the effect of a port so would have the same advantages/disadvantages musically. However, the passive radiator makes it MUCH easier to tune the box (change sizes, change weights, etc) without having to build a port. It eliminates chuffing as well.
Interesting video!! Watching this, my mind went straight to those JBL speakers that use "passive radiators" to emmit their bass, but are essentially still sealed
it is similar like vented regarding the frequency characteristic. but there is no port noise and you maybe have a tiny bit more dampening which leads to more accuracy.
Good explanation , sealed subs have always had musicality on their side . They are able to recreate the lower registers of the musical spectrum. A ported sub is good for bang bang -- boom boom , personally I would much rather have lower musical notes that just a bang and a boom !!
Summs it up. Building a sealed speaker has the advantage that you can quite precisely create your desired "Sound-Design" by the inside Volume (Qtc) of your housing. For a good vented speaker your driver probably will be more expensive then the driver matching a sealed Box design. If you want low bass range for a small driver you have to go for the ported speaker. If you want low bass range in a sealed subwoofer the housing easy gets huge. For people who don't really car much about sound a cheap 2.1 system with a vented sub will just do fine. I got one of these, was under 30$ and for that money it can't get much better. On the other hand, you can buy high prized speakers that are crap. It's mostly just about marketing. A good speaker system is one, that you can enjoy listenimg too all day long, without getting nuts.
Wouldn't a sealed sub overheat n burn if u r really pushing it...n u can't smell it. A ported box would provide better cooling n u would smell it starting to burn...
4 minutes in, in regards to the "overshooting" of ported subs, and the sealed sub sucking the cone back in, I mean that's inaccurate. Ported subs actually have much higher internal air pressures than sealed, due to the backpressure of the ports. If you look at the excursion of each, the sealed sub will actually move much more than a ported sub. Near the tuning frequency the cone is actually very still on a ported sub which is why you always get a big impedance dip, that backpressure is holding the cone in place. All you have to do is cover up the port while it's playing a bass note and you can see that it will instantly start to move more. This is the opposite of what this guy is saying. The only time this is true is when it's below the tuning frequency and the driver is unloaded, it will flop like a fish out of water, very sloppy. Acting like this is the norm for all frequencies just isn't reality.
I would like You to talk about fidelity facts and not power facts, because i like fidelity, listen Crystal clear what the misician and audio ingeneer wanted to transmit. That info is much more interesting for me and harder yo find. Do i make a sealed, vented, T.L.? What is Best? Do i use a paper cone? Sintetic, silk? Tweet? Compresor? Open box????
too bad you neve actually DEMOed the SQ vs extension battle. if you REALLY want to win a debate with hard headed port lovers who DAREs point out that they love DISTORTION, do waterfall plots for the same woofer ported and stuffed. just don't do it with flimsy cabinet speakers where plugging trades port resonance for box resonance **cringe**
All this sounds good on paper but my ears tell me a different story….ported sounds way better to my ears than sealed. Sealed boxes suck the life out of subs. I have ported subs of all sorts…no distortion or port chugging for me.
I read this as you build small subs, that make tight inaccurate base that you can feel more at the bottom end. You made that concession because small format is your objective, not sound.
ported are better overall..only reason you should ever go sealed for is complete lack of space for ported..but if you DO ever go sealed..always go for a minimum of a 15 inch driver...nothing smaller because it will be boring ...ported is better..far more efficient
Wrong. Audiophiles only use sealed boxes, or active passive sub boxes. If all your want is loud boom sound and don't care about distortion, then be a 15yr old forever.
I run 3 sealed 12" subs, my entire system was not cheap (I'm an electrician and project manager) but the sound is amazing. Proper placement of subs and mounting then down is a big advantage.
@@Rico702Vegas you do realize audiophiles are also a bunch of idiots right ? they don't even like subwoofers because they think they are slow..they are very subjective and non factual ..you can't check audiophiles you need to check audio ENTHUSIASTS !!!
@@Rico702Vegas 3 12 inch sealed huh..but no bass down to 10hz..what a waste ...and a single ported would've blown all those away easily and still play lower
The benefits are it is capable of lower frequencies and produce more sound with less power although less accurate. Typically if you listen to mostly rap music and or dubstep you may want ported. If you listen to a variety of music types or mainly drums sealed is the choice. IMO
Why have you stopped production of the sub6? People need a compact but hi-fi audiophile grade sub to listen to their records without flooding small rooms with tons of base... We are in need of small but audiophile grade subs! Not power hungry but musically rich and precise. There is no chance one can find a sub6 on the market any more. That shows the actual market interest in this product and not in huge ported woofers. Of course price is to be considered. If you manage to come with a nice design, well built, musical and compact subwoofer around EUR 150-200 (for EU market) it will be sold in a blink of an eye. Better EUR150. 😉 If Edifier can do it you can also.
some of yall need to learn what dynamat is lol. you can get the bass without the rattles. 07 Silverado daily driver 2 12inch Kicker VX hidden under the seat custom ported enclosure 35hz tuned. 6 kicker 6x9s Kicker kxa 1800.1 kicker kxa 500.2 whole truck sound dampened. Shit bangs and turns heads. i do wish i could get two l7 15ins in there under the seat though.
I put a capacitor and a small coil on the negative line. Slowing it down and therefore creating a lower frequency. In a small space enclosure ( under a car seat ) it gives the thump that you’re looking for.
So, here's a suggestion for a future video... Soundbars. I see these commercials for sound bars where the camera is focusing on the sound bar and everybody's talking about the sound bar and everybody is dancing around the sound bar and the sound bar is dancing itself and spinning around and it has cool lights and look how cool the sound bar is. There is almost never any focus on the sub. Why? Because the sub is usually junk. Even the most expensive sound bars have junk subwoofers. Most people don't notice or can't tell, all they know is the room shakes when the dinosaur stomps across the screen. I am particularly irked by this nosebleed expensive gamer sound bar, the ads for which are exactly as described above. The sound bar itself seems to be well designed, although plasticy, but the subwoofer is the same POS pressboard junk with no removable grill, with a single cord pre-attached drilled through the cardboard back. Just once, I would like to see some manufacturer supply a decent subwoofer with their soundbar. Rather than by the nosebleed expensive high-end gamer soundbar, I bought a Black Friday special powered sub, admittedly a much lower quality than what you guys sell, and just ran the through signal into my fairly cheap existing PC sound bar. Problem solved, and of relatively equal if not Superior audio quality. Would really love to see a video about this. I assume the phenomenon of cheap soundbar subs is about the economy of scale. In terms of PC or gamer rigs, almost all of them look exactly the same. So do most all of the low end sound bar models that have subs, there seems to be one or two types of cheapy sub that are almost universally used. Thanks for the great video.
eh.. sealed oxes have max cone movment at fb. ported ones have the least. ports chuffing is not an issue. port pipe resonance is. may or may not choose a sealed my self, both have some good points. if i want a small sub... isobaric is allways my friend.
I use a Veliodyne IMPACT-10 ported subwoofer and it's awesome. i prefer ported over sealed because not only does it provide louder bass output, it also provides cooling for the plate amp and the driver itself. In a sealed box, the heat generated from the amp has nowhere to go, and that could be a bad thing. I don't know how they manage to keep sealed subs from breaking due to overheating.
1. Class D 2. Plate itself is a cooler, some amps have heatsinks on the outside 3. There's a significant amount of air inside the box, in a lot of cases its capacity is more than enough to cool down what's needed
With a smaller enclosure you lose efficiency. A vented enclosure works like a sealed enclosure when the woofer is playing out of the range of the port. Room placement is important for a low frequency driver in home use.
Ported costs more to build, store and ship, and is bigger, so a fair comparison is hard to make. You could give the sealed sub a better amp or driver and it might end up giving better overall performance.
I have never ran a ported sub in my car and oddly enough I have never ran a Sealed sub in my house. I have found bigger spaces are better for ported. My car being a small space and all the speakers being so close to me I can hear distortion much sooner than in the house where I run 7.2 surround and the subs are further away from me. Plus I'm one of those weird people who isn't interested in what the other car at the stop light can hear. I don't need cops or thieves' attention on my car.
they are all myths that he says ... you can see he hasn't opened a sound engineering book in the slightest. speaks of closed box or box ported so without even mentioning the principles thiele & small ... they are information to be taken with a grain of salt
Some speakers are made fore sealed boxes, some speakers its fore ported boxes, and there its the biggest difrent of whay there its so, And another thing , its the difrent of active and passive subwoofer boxes its the amplifier not livning so long like the speaker do of a Aktive subwoofer do, thats the passive subwoofer its a better Alternative here
Below the tuning frequency, ported sub driver has enormous excursion as you go down. Sealed on the other hand has limited low excursion even below tuning frequencies. One more advantage of sealed is that the woofer membrane remains rigid compared to vented because the pressure difference in case of sealed across the woofer stays high at extremities as compared to the woofer in vented.
I built by own box and designed my own port for a sub to go in my 96 civic in high school. I paired it with a cheap pioneer amp and woofer. tried to set it all up to roll off pretty heavily around 40 hz. I thought that would protect the speaker. I was the designated driver to a party one night. my friends were all pretty excited to hear the system I put together. non of us cared to much about sound quality at the time. we cranked the volume and destroyed the sub. I learned the hard way that if you are using a ported box you need to quality sub that won't rip itself apart easily. I never did replace that speaker.
Fair reasoning but why not use a passive radiator u don't have the distortion of a ported and you get louder and deeper than sealed so why seal when u can use passive radiator with the same size box and get more?
@@parmanusir after further learning in a lotnof cases u still need a bigger box than something like a sealed but not the same size as ported but u can dsp the sub to perform even better also its definitely got its downsides the main one being price 8in radiators are like 30 dollars so instead of just having a simple sealed box that's perfectly matched for the sub then eq the sub to give it more of that 30hz like a 3 or 6db boost like svs does if they didn't they would not in any way have the same performance because there sb1000 is a 12 I think and it's sealed and the box its in is like 14x14x14 or something similar then the sub displacement and amp displacement u have a 12 in a barley 1 cubic foot box if your lucky u have to eq it if u want any decent performance and they will get down to 20hz but ported is louder and way louder if u eq it and they don't cost anymore technically both ported and sealed are about the same in price other than the box being a decent amount bigger and the material used to make a port u lose control in ported too there's a ton of ups and downs to each but if u have the budget and the knowledge and want the sound of ported and don't mind the price I'd still say it's a great option there all great it just depends on your application in honesty to me ported is the easiest there's tons of math for it it offers the best performance at its price and u dont have to have a fancy or expensive eq for it its just the easiest to do in my opinion if you do the box and port right you'll get great performance good cone control no port noise and if u want to dsp or eq u can get some even better punch so imo ported is best but they all have there place
Bass is Distortion it's vibration Bass is not made to sound crystal clear and bass is not meant to be heard it's vibration its meant to be felt as I call it a deaf persons music
I own a Genelec subwoofer with Laminar Spiral Enclosure bass reflex cabinet. It provides excellent laminar flow characteristics with minimal turbulence noise and allows for a long reflex tube into a small space. It sounds amazing, no chuffing, and is perfectly clear no matter how loud.
A bit misleading, this from someone who built & enjoys 2- 15" sealed subs. A properly designed ported sub is the way to go when we're talking about an 8" driver.
Recently i bought epos els sealed 10 inch sub...it changed completely my home theater experience ..wow...amazing..it gives immersive experience through out the whole movie
I was a hater for sealed subs until I sealed a 4 inch soundbar subwoofer Lol😂, before seal (poor port design) 72 Hz Fs, After Seal response down to 44 Hz! Soothing bass
Spot on description. Sealed subwoofers are preferable for music; they sound more controlled/more responsive and precise compared to ported, that might be better for surround sound. Many small ported wall speakers should have their ports blinded with foam or other materials to make them more tight and better sounding. Especially if placed right agains the wall. Deep bass is not everything 😉
9 out of 10 submariners prefer sealed subs 😉
because the last 1 cannot pick any preference from the crushing depth of the ocean...
Yeah but if your idea of an ideal subwoofer is one that booms the loudest and rattles the most nearby car windows at the stoplight, you definitely want a ported system.
I wanna be able to hear it and feel it
imo i want a clean sound that doesnt rattle but you can still hear it
I want that rattling

As a fellow melomaniac, I like your line of thinking on this subject. Maybe one the highly trained audiophiles can explain why this isn't practiced. Sounds like a good idea to me.
I thumbs up soon as you gave the bottle demonstration. That's such a perfect example!
I used to always automatically go for large ported subs. It seemed common sense they would dig deeper and be better for movies. This all changed when I was gifted a small little Martin Logan Dynamo 10" sealed sub. It utterly destroyed my SVS. It plays clean to the low 20s and also has really tight punchy bass. Best of both worlds and I've never owned a ported sub that did both of these things well. Was blown away by that little ML sub.
Which svs...? Ultra 16?

@@Stan_the_Belgian maybe pb1000😂
@@benboyer2776- design and quality components matter. That Martin Logan was probably much more expensive too. I went from a huge 400w sub to a REL (T2) 10” with passive radiator that was better at basically everything. Music and movies. It was more $$$ of course.
Two words. Passive radiator. Best of both worlds. Put one in there and I might buy one.
That is my experience as well, when testing subs the REL with a passive driver sounded the tightest and is roughly the size of the Kanto :)
@@jedics1i cant stand port chuff. Thats the worst part of porting.
not exactly... passive radiators have uneven frequency responses. If you want more QUANTITY out of sealed... just add more power + EQ or drivers. I DESPISE boomy flabby bass. The first time bass wowed me was infinity 4 1/2" 2 ways! the bass was soooo tight and fast, if not chest thumping. I'll take quality every time
Thanks for this explanation! In building custom boxes for my truck I noticed when I added ports as I was meant to I lost clarity, this clearly tells me that what I want is a sealed box 👍
I always used sealed boxes, my last had 2 JL w3s nice and clean. Miss them.
Are you sure those ports were properly engineered? Probably not.
So how would you compare the sealed subwoofer to one that has a passive radiator?
that's what I thought of
A passive radiator essentially mimics the effect of a port so would have the same advantages/disadvantages musically. However, the passive radiator makes it MUCH easier to tune the box (change sizes, change weights, etc) without having to build a port. It eliminates chuffing as well.
Interesting video!! Watching this, my mind went straight to those JBL speakers that use "passive radiators" to emmit their bass, but are essentially still sealed
it is similar like vented regarding the frequency characteristic. but there is no port noise and you maybe have a tiny bit more dampening which leads to more accuracy.
Good explanation , sealed subs have always had musicality on their side . They are able to recreate the lower registers of the musical spectrum. A ported sub is good for bang bang -- boom boom , personally I would much rather have lower musical notes that just a bang and a boom !!
And the boom from a sealed sub is usually still exciting and impactful (vs not having a subwoofer)
Summs it up. Building a sealed speaker has the advantage that you can quite precisely create your desired "Sound-Design" by the inside Volume (Qtc) of your housing. For a good vented speaker your driver probably will be more expensive then the driver matching a sealed Box design. If you want low bass range for a small driver you have to go for the ported speaker. If you want low bass range in a sealed subwoofer the housing easy gets huge. For people who don't really car much about sound a cheap 2.1 system with a vented sub will just do fine. I got one of these, was under 30$ and for that money it can't get much better. On the other hand, you can buy high prized speakers that are crap. It's mostly just about marketing. A good speaker system is one, that you can enjoy listenimg too all day long, without getting nuts.

Testing subwoofers without sounds LOL
this channel certainly has potency :D
Wouldn't a sealed sub overheat n burn if u r really pushing it...n u can't smell it. A ported box would provide better cooling n u would smell it starting to burn...
4 minutes in, in regards to the "overshooting" of ported subs, and the sealed sub sucking the cone back in, I mean that's inaccurate. Ported subs actually have much higher internal air pressures than sealed, due to the backpressure of the ports. If you look at the excursion of each, the sealed sub will actually move much more than a ported sub. Near the tuning frequency the cone is actually very still on a ported sub which is why you always get a big impedance dip, that backpressure is holding the cone in place. All you have to do is cover up the port while it's playing a bass note and you can see that it will instantly start to move more. This is the opposite of what this guy is saying. The only time this is true is when it's below the tuning frequency and the driver is unloaded, it will flop like a fish out of water, very sloppy. Acting like this is the norm for all frequencies just isn't reality.
I would like You to talk about fidelity facts and not power facts, because i like fidelity, listen Crystal clear what the misician and audio ingeneer wanted to transmit. That info is much more interesting for me and harder yo find. Do i make a sealed, vented, T.L.? What is Best? Do i use a paper cone? Sintetic, silk? Tweet? Compresor? Open box????
too bad you neve actually DEMOed the SQ vs extension battle. if you REALLY want to win a debate with hard headed port lovers who DAREs point out that they love DISTORTION, do waterfall plots for the same woofer ported and stuffed. just don't do it with flimsy cabinet speakers where plugging trades port resonance for box resonance **cringe**
All this sounds good on paper but my ears tell me a different story….ported sounds way better to my ears than sealed. Sealed boxes suck the life out of subs. I have ported subs of all sorts…no distortion or port chugging for me.
I read this as you build small subs, that make tight inaccurate base that you can feel more at the bottom end. You made that concession because small format is your objective, not sound.
Exactly. Sealed is all about the smaller size, at the expensive of ultimate performance.
chuffing does not happen at reasonable volume levels. Ported enclosures are not complicated or difficult to build at all.
ported are better overall..only reason you should ever go sealed for is complete lack of space for ported..but if you DO ever go sealed..always go for a minimum of a 15 inch driver...nothing smaller because it will be boring ...ported is better..far more efficient
Wrong. Audiophiles only use sealed boxes, or active passive sub boxes. If all your want is loud boom sound and don't care about distortion, then be a 15yr old forever.
I run 3 sealed 12" subs, my entire system was not cheap (I'm an electrician and project manager) but the sound is amazing. Proper placement of subs and mounting then down is a big advantage.
@@Rico702Vegas you do realize audiophiles are also a bunch of idiots right ? they don't even like subwoofers because they think they are slow..they are very subjective and non factual ..you can't check audiophiles you need to check audio ENTHUSIASTS !!!
@@Rico702Vegas 3 12 inch sealed huh..but no bass down to 10hz..what a waste ...and a single ported would've blown all those away easily and still play lower
"see you in the next video" HAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHAHAHAH!!!!
Chill bro it wasnt that funny
Maybe I missed it but did you mention the benefits to ported subs? Surely there are pros and cons to each, so what are the pros?
The benefits are it is capable of lower frequencies and produce more sound with less power although less accurate. Typically if you listen to mostly rap music and or dubstep you may want ported. If you listen to a variety of music types or mainly drums sealed is the choice. IMO
@@SSMan-jo6tf problem with sealed is you need a lot of power. A 800w 12" ported sub easily outpaces my 13" 1000w sub.
Both have pros and cons.
@@SSMan-jo6tf It also depends on your primary use for the sub such as listening to music vs watching movies on your home theater.
Why have you stopped production of the sub6? People need a compact but hi-fi audiophile grade sub to listen to their records without flooding small rooms with tons of base... We are in need of small but audiophile grade subs! Not power hungry but musically rich and precise. There is no chance one can find a sub6 on the market any more. That shows the actual market interest in this product and not in huge ported woofers. Of course price is to be considered. If you manage to come with a nice design, well built, musical and compact subwoofer around EUR 150-200 (for EU market) it will be sold in a blink of an eye. Better EUR150. 😉 If Edifier can do it you can also.

Go for a passive radiator... no chuffing and they are far tighter
LARGE SEALED BOX FOR ME...take the size they recommend for ported and build it sealed.
I put a capacitor and a small coil on the negative line. Slowing it down and therefore creating a lower frequency. In a small space enclosure ( under a car seat ) it gives the thump that you’re looking for.
I made my own 15” 600w PA sub with a wave guide that I built in it
The port has a 4inches in height and 16,5 inches in length
It’s hits hard!
So, here's a suggestion for a future video... Soundbars. I see these commercials for sound bars where the camera is focusing on the sound bar and everybody's talking about the sound bar and everybody is dancing around the sound bar and the sound bar is dancing itself and spinning around and it has cool lights and look how cool the sound bar is.
There is almost never any focus on the sub. Why? Because the sub is usually junk. Even the most expensive sound bars have junk subwoofers. Most people don't notice or can't tell, all they know is the room shakes when the dinosaur stomps across the screen.
I am particularly irked by this nosebleed expensive gamer sound bar, the ads for which are exactly as described above. The sound bar itself seems to be well designed, although plasticy, but the subwoofer is the same POS pressboard junk with no removable grill, with a single cord pre-attached drilled through the cardboard back.
Just once, I would like to see some manufacturer supply a decent subwoofer with their soundbar.
Rather than by the nosebleed expensive high-end gamer soundbar, I bought a Black Friday special powered sub, admittedly a much lower quality than what you guys sell, and just ran the through signal into my fairly cheap existing PC sound bar. Problem solved, and of relatively equal if not Superior audio quality.
Would really love to see a video about this. I assume the phenomenon of cheap soundbar subs is about the economy of scale. In terms of PC or gamer rigs, almost all of them look exactly the same. So do most all of the low end sound bar models that have subs, there seems to be one or two types of cheapy sub that are almost universally used.
Thanks for the great video.
Some people want to sacrifice accuracy for more loud booms. But I am a person of quality over quantity, thus happy with sealed sub.
eh.. sealed oxes have max cone movment at fb. ported ones have the least. ports chuffing is not an issue. port pipe resonance is. may or may not choose a sealed my self, both have some good points. if i want a small sub... isobaric is allways my friend.
I use a Veliodyne IMPACT-10 ported subwoofer and it's awesome. i prefer ported over sealed because not only does it provide louder bass output, it also provides cooling for the plate amp and the driver itself. In a sealed box, the heat generated from the amp has nowhere to go, and that could be a bad thing. I don't know how they manage to keep sealed subs from breaking due to overheating.
Put a bottle of ice water near the port to chill it out. It will thank you...
1. Class D
2. Plate itself is a cooler, some amps have heatsinks on the outside
3. There's a significant amount of air inside the box, in a lot of cases its capacity is more than enough to cool down what's needed
they manage tho
with a modern class D amp the cooling is not a problem at all.
With a smaller enclosure you lose efficiency. A vented enclosure works like a sealed enclosure when the woofer is playing out of the range of the port.
Room placement is important for a low frequency driver in home use.
Great video, just one question....more companies are using passive radiators instead of ports. What are the pros & cons of these ?
Ported costs more to build, store and ship, and is bigger, so a fair comparison is hard to make. You could give the sealed sub a better amp or driver and it might end up giving better overall performance.
I want much smaller/shallower sub with passive radiator. And it will not ruin the speaker cone and rubber edge in most longer strokes.
Sealed also have less problems with room positioning. And all ported have "bass delay".
*fewer
I have never ran a ported sub in my car and oddly enough I have never ran a Sealed sub in my house. I have found bigger spaces are better for ported. My car being a small space and all the speakers being so close to me I can hear distortion much sooner than in the house where I run 7.2 surround and the subs are further away from me. Plus I'm one of those weird people who isn't interested in what the other car at the stop light can hear. I don't need cops or thieves' attention on my car.
That's all fine and dandy. Except for a lot of artist, country and rock included in metal, not just rap, produce lowe's twenty heart frequencies
they are all myths that he says ... you can see he hasn't opened a sound engineering book in the slightest.
speaks of closed box or box ported so without even mentioning the principles thiele & small ...
they are information to be taken with a grain of salt
Well, he talked about buying a speaker, not building one. In that context his information was accurate, i.m.h.o.
Air is going out AND in the port, so comparing it with water just flowing OUT of a bottle..............
I have a Bowers and Wilkins sealed type and it is superior my ported Pioneer one which itself is very good.
very good explanation.
i like a sealed dual subwoofer architecture where the chassis are opposing each other.
Some speakers are made fore sealed boxes, some speakers its fore ported boxes, and there its the biggest difrent of whay there its so,
And another thing , its the difrent of active and passive subwoofer boxes its the amplifier not livning so long like the speaker do of a Aktive subwoofer do, thats the passive subwoofer its a better Alternative here
Why doesn't Kanto like bigger woofers??????? You guys should have a fuckin 12" wth
Normies: people who crank stereos are uneducated. Physics, thermodynamics, and electrical engineering have all left the chat.
Ported anything is for crappy and weak speakers. Porting a powerful good speaker will result in bad sound or a huge, non-practical enclosure.
Below the tuning frequency, ported sub driver has enormous excursion as you go down. Sealed on the other hand has limited low excursion even below tuning frequencies.
One more advantage of sealed is that the woofer membrane remains rigid compared to vented because the pressure difference in case of sealed across the woofer stays high at extremities as compared to the woofer in vented.
7:44 Key word "musical". For those of you looking for a home theather experience, not a misical experience, ignore this video.
Hopefully if there's demo it would help a lot rather than explain that I can't understand.... 😒😒😒😒😒
? You dont like the sound of a ported sub than shove a dirty sock in the port hole! If you are sealed and want to switch to ported than.....screwed!
One big commercial pitch for their subs.... Hi im ron popeil and have i got a subwoofer for you... Lol
I built by own box and designed my own port for a sub to go in my 96 civic in high school. I paired it with a cheap pioneer amp and woofer. tried to set it all up to roll off pretty heavily around 40 hz. I thought that would protect the speaker. I was the designated driver to a party one night. my friends were all pretty excited to hear the system I put together. non of us cared to much about sound quality at the time. we cranked the volume and destroyed the sub. I learned the hard way that if you are using a ported box you need to quality sub that won't rip itself apart easily. I never did replace that speaker.
Frequency below tuning will damage the speaker.
You ported it too high
for those who come here to hear those 2 speaker sound. prepare for a disappointment. you only here that annoying bearded lady in the front
is nobody talking about the fact he has 2 watches on
He's very fashionable
@@KantoSolutions 😂😂😂
Fair reasoning but why not use a passive radiator u don't have the distortion of a ported and you get louder and deeper than sealed so why seal when u can use passive radiator with the same size box and get more?
That's ok if it doesn't leak, and u have to use the right coolant
Awesome thinking!
@@parmanusir after further learning in a lotnof cases u still need a bigger box than something like a sealed but not the same size as ported but u can dsp the sub to perform even better also its definitely got its downsides the main one being price 8in radiators are like 30 dollars so instead of just having a simple sealed box that's perfectly matched for the sub then eq the sub to give it more of that 30hz like a 3 or 6db boost like svs does if they didn't they would not in any way have the same performance because there sb1000 is a 12 I think and it's sealed and the box its in is like 14x14x14 or something similar then the sub displacement and amp displacement u have a 12 in a barley 1 cubic foot box if your lucky u have to eq it if u want any decent performance and they will get down to 20hz but ported is louder and way louder if u eq it and they don't cost anymore technically both ported and sealed are about the same in price other than the box being a decent amount bigger and the material used to make a port u lose control in ported too there's a ton of ups and downs to each but if u have the budget and the knowledge and want the sound of ported and don't mind the price I'd still say it's a great option there all great it just depends on your application in honesty to me ported is the easiest there's tons of math for it it offers the best performance at its price and u dont have to have a fancy or expensive eq for it its just the easiest to do in my opinion if you do the box and port right you'll get great performance good cone control no port noise and if u want to dsp or eq u can get some even better punch so imo ported is best but they all have there place
Silly, no mention of the port tuning.. then saying the low frequency drops off on a ported sub!!
" Sealed subs are normally more accurate than ported subs ". Open baffle subs mess that opinion up.

I own a Genelec subwoofer with Laminar Spiral Enclosure bass reflex cabinet. It provides excellent laminar flow characteristics with minimal turbulence noise and allows for a long reflex tube into a small space. It sounds amazing, no chuffing, and is perfectly clear no matter how loud.
I have one as well, and it has a crossover to limit the bass going to my Genelec mains. Sounds great.
One of each in your system.
Next problem, I'm solving everything
Infinite baffle ultimately wins...if application can be ve accommodate

Sealed is better, if you ask me.
I do not like bass on ported speakers. To undefined.
A bit misleading, this from someone who built & enjoys 2- 15" sealed subs. A properly designed ported sub is the way to go when we're talking about an 8" driver.

I like ported more then sealed cuz i like deep bass also i wont make my sub cry
I don't like this video because of he didn't play music on it
but why some subwoofers have "membrane" thing instead of hole?
Spot on description. Sealed subwoofers are preferable for music; they sound more controlled/more responsive and precise compared to ported, that might be better for surround sound. Many small ported wall speakers should have their ports blinded with foam or other materials to make them more tight and better sounding. Especially if placed right agains the wall. Deep bass is not everything 😉
Well here I was coming to promote my low end freq album exposition “Chuffed and Buffed” - apparently I came to the wrong niche 😂
