Years ago the speaker home setup was to have a sealed box with a low Q of about 5.7(large box). It's now hard to find a woofer with the right specs to go this route. I ran this setup a while back and now run vented. Most of the systems today run vented, lower F3 and play louder but I feel with room gain and the slower drop in decibel from the sealed box, they are about the same bass output.
You are Right, I went from a ported to a sealed sub. It is corner loaded, and I don’t have the impression to miss anything from my ported sub. I even have flat response till 10Hz on the sealed one!

Your background music and your voice are at war at the same frequencies. It may sound good on your speakers you mixed it with but not everyone has your speaker setup. Choose a better music that doesn't drown your voice or lower the volume.
I bought a 2x12 inch ported sub quite a few years ago, and i listen to music in the high bpm range (180-210) and i could for the life of me never understand why the base was lagging behind the melody. I thought it must be something wrong with my stereo/monoblock setup, i had a few suspects but i never could figure it out, or as the local professional car audio was pretty much unapproachable i never got an answer until now...
I agree. I cannot concentrate on what he's saying as the music is the same level as his voice for me. I love music but not while i'm trying to listen to technical info. I wonder if HexiBase would re-upload this without the music.
Thank you for sharing all your knowledge with the world. You are like the Einstein of sound. I wish you were giving classes near my town. I would sign up for all of them. Keep up the amazing work !
I just went through this decision process.. I bought a SKAR EVL-10 D2 to be run with my Rockford Fosgate 1200D1 Prime.. It is in my 2012 GMC Sierra extended cab. The only space I had to use is where the jump seat used to be in the middle of the front seats. Specs for the sealed enclosure allowed me to build my box and mount the original armrest on it.. I am extremely happy with it as I am more into the SQ anyways.
I remember when I worked at Circuit City, I just wanted a simple single 12" sub and the employee discount was pretty much %50 in car audio. I grabed an MTX Blue Thunder Legend 12" and the specs said 1 Cubic foot for sealed so I grabbed a simple 1 cubic ft sealed enclosure. My god, you would have thought I took a dump right on the floor. "Oh no, you need a bandpass box", "you won't get enough bass" etc. I stuck with the sealed and threw a simple 250 Watt RMS amp and a crossover on it and placed the box about 2.5 feet from the back hatch in my 280xz. That damn thing was too much bass in that car. All they could talk about the next day was how much output it had in a hatchback. I don't think they really knew much about acoustics.
Yeah sealed will work better in a car. You just don't need the extra output/efficiency of ported. Also ported has gain down low so unless you EQ it, I'll be too bassy and boomy
yo yo, an old school enclosure junkee here. Bobby Gately and MBenclosures are my homies. The former is local to me, and i watch MB, so much might as well l know him!!! Bobby moved me to the"ported side" ,after years being exclusively sealed. Ant Hex, thanks for dropping enclosure knowledge, I like it very much
All speakers are a compromise and every design has pros and cons. But if you’re an audiophile and prefer quality over quantity, and want accuracy, good transient response, smooth low frequency roll off, good power handling and cone control, and a practical sized enclosure(especially in the tight confines of an automobile) then a sealed system is the logical choice. The better sound quality will far outweigh the few dB of efficiency you are sacrificing. Besides, amplifier power is much more affordable now. I love these videos. Finally someone that speaks my language. Keep up the great work.
for me by the time power compression and the distortion that comes with it kicks in, your better better off with a low tuned ported tuned just slightly below fs (like 20hz for a 25hz fs) this pushes the sound of the port into a faster slope thus eliminating it earlier, also by the time you hit 40 hz your out of the group delay region and we generally cant hear it below that mark. you also avoid the added delay of an eq that your sealed needs.
I like the large and low tuned design myself and found over many years have building and experimenting that that works the best. I tuning frequency of 8 Hertz works out well for handling all the frequencies above 10 Hertz with a minimal group delay.
Thats why im building my own box and learning as much as i can but i have learned alot more from your change then most other please keep bringing the knowledge
Have to admit, I do like fact based videos over someones opinion of why they like a particular sound, or why we should agree with their choice. This was a straight up you make your own decision.
1:54 This lends to an interpretation of the source material. If you've ever listened to a track at 0db gain in the bass region (which I know you have), it can be very unrewarding. At this point we become the mixer, and decide where the bass should be (as well as the other Hz if you have the ability). I feel like +6db bass is not out of character for the original intention of the song in many circumstances.
And that’s why one should be careful and watch that clipping indicator when listening to regular music (more specifically rap with the amount of distortion, +6db peaks, tryna play 2 frequencies at once to name a few…
I ported a home made cabinet that was used with a 15" EV for a bass guitar. This cabinet covers my high end, and I use an18"CV for my low end. I hit the library to learn how to tune it to 50 hz. If the volume or tone were affected, the effect was miniscule compared to what the amp does. But I can say for sure that the port made it much more responsive to the volume variations of my touch than it previously had been, and the freedom of motion of the speaker allows much better sustain.
Sealed subs require more power and more excursion to reach the same spl levels as their ported counterparts. More power + more excursion = decreased linearity and so more distortion. The only advantage to sealed subs are lower extension (think 10hz below) and size. In a low tuned ported cab the driver will sound the same above 30hz (music region) than its sealed alternative!
Please do a video on Aero Ports! Baffles, no baffles, side/baffle/front/back mounted port, port opening in relation to subwoofer location, port center vs corner, adding bends to achieve length without having port hang out of box etc. That would be awesome!
Your channel is criminally underwatched. I thought I knew a little bit about audio but you keep making me realize just how much I do not know. Don't even know where to start to learn all of this. Fantastic work!
WOW! And here when I first started to watch this I was already prepping my "but the laws of p[hysics!" reply as few people accurately describe the blurring/ phaseshift/ delay.... produced by allowing the back of the speaker's accoustic energy to enter the listening room. But you even provided a graphic showing it! Now my Maggies however.... I will be checking out more of your stuff!
True that sealed enclosures can have "tighter" bass, but some well reviewed ported systems (such as those by Ohm Acoustics) have received high marks for their tight bass response. One of the (claimed) advantages of porting is to have as good bass as sealed systems but in smaller enclosures.
I have 8inch subs with port id compare them to 12inch subs in closed box mine sound smoother but my friends more thumping but distorted in a way were both running 500watt not much but were budget builds id do ported most the time as long as the ports right but ive seen them done wrong with over sized ports that couldn't do tight bass like my ported box
@@toxictophat711, exactly correct. A smaller woofer will give tighter bass and mid bass. But a larger woofer can give deeper bass. Ideally, porting or using a passive radiator (drone cone) is sometimes better than a sealed woofer. With ports, the size of the opening is critical to good sound. Lots of choices but I prefer tighter bass to deeper bass that's muddy and boomy. That ain't hifi and just sucks. Fuhgeddaboudit!
@@martyjewell5683 The common misconception that a smaller driver produces "tighter" or more responsive bass has been debunked time and time again. I wasted a lot of money when I believed that by buying many 10" woofers as opposed to one 15".
And then there is the transmission line. Technically ported but with a twist. I have yet to build one but it is purported to something of a middle way. Since there are so few really good drivers available these days with a Qts suitable for sealed use (at least in home stereo environment) it may be a way to get decently clean bass with lowish Q drivers.
One matter you did not cover, that I would love to hear your take on. All bass drivers entail certain physical and electrical properties that make them a good fit for either a sealed or a vented alignment. Regarding vented alignments, I find that the size of the vented box may vary greatly. For example, given two 12 inch bass drivers for vented enclosures, one may call for a very large box volume whereas the other may call for a much smaller box volume. Assuming the two bass drivers are of equal quality, I have found the listening experience of these two bass driver systems to be radically different, the small box version sounding very stuffed and muted, and the large box version sounding very full, airy, and more natural (like real bass instruments). Unfortunately, manufacturers of subwoofers steer clear of large vented alignment systems since the very large boxes would not sell with the general buying public. So all that anyone sees is small box systems, either sealed or vented. I find the large vented alignment systems (and I have built over a dozen of them) are very pleasing, whereas the factory sub woofers always disappoint by comparison. Something for folks to think about.
Without experience or expert knowledge i have an feeling for what you're saying . a large ported box definitely sounds better. I think its industry jargon used for selling points. Like most experts they impose their knowledge over the persons listening reality.
On the other hand, if most people will not accept a pair of very large boxes (2-3 cubic feet each) in their listening space, then I guess it doesn't really matter how much better they sound vs small box systems. I actually feel the same way about extremely expensive electronic components. The amp or CD transport or DAC or tube pre costing thousands each may all sound better than my @ $500 a piece components, but since I am unwilling to spend that kind of money on my components, then it doesn't really matter if they sound better.
I like it when clients become experts because their buddy or a auto glass shop recommended an enclosure. Only to be blown away by a sealed or ported enclosure they didn't' expect to sound the way they wanted. Sealed or ported? Yes.
For my front speakers I am using the 18" GRS 18PT-8 in a 4 cubic foot sealed enclosure it can go 3db down at 41.6Hz. It just sound is incredible. But for the subwoofer I use ported and use it for frequencies just below the GRS based speakers. When using the ported speaker for a subwoofer at frequencies that low you will not be able to tell any effects of slower transience.
In a car I prefer the softer and more boomy sound of a ported enclosure over the harder and sharper sound of a sealed enclosure.... in the house I prefer the exact opposite but with a larger cone diameter that would be unrealistic in a car... but only when I'm listing to music, if it's for movies & TV, small sub in a sealed enclosure so the sound can keep up with the action... that clears everything up... right!?
That really made no sense. Ported boxes arent softer (boomy maybe I'd poorly designed) and sealed boxes are not 'harder' or 'sharper'. Im really not even sure what you're trying to say with that description.
Your presentations are so low key. If one doesnt really tune in, its easy to miss something. You present clear concise extrapolations on the topic. Thank You. Liked and Subbed.
Every time I have been "wowed" by a home system, the Sub was running a passive radiator. SO I have come to rely on them for my own stuff, far easier to "tune" and to my ears, far better sounding...
@@skyoptics ... ALL ports create secondary wind noise... Unless they are so over sized, that you might as well be holding the woofer in your hand, for all the good the box is doing.
Love your videos about woofers & boxes you make things understandable for us noobs & I'm sure with all these informative videos I'll be able to make a really good enclosure soon enough, I've made some that work really well but never really had exactly what I wanted
Awesome, I'd like to know what education you had to bring you to that level of understanding. Couple of quick questions, does a enclosure with two drivers have to have a divider? What is your opinion on using poly fill in enclosures? More videos please! Watching / Learning from Virginia.
@@HexiBase the reccomendation of mineral wool made me pause...correct me if i am wrong, but it is a very dangerous material to work with www.bing.com/videos/search?q=mineral+wool&docid=608025939454722974&mid=B57934B61B48A24B0973B57934B61B48A24B0973&view=detail&FORM=VIRE&PC=SMSM
With a similar driver. An optimally designed ported enclosure is actually comparable to 3 closed at the frequencies where the port is active. Such a enclosure produce way less distorsion due to the lower cone displacement (assuming an optimal port), at the same spl. Under the resonance frequency closed are more efficient. The difference between the different enclosures are mainly group delay. Reflex boxes having higher gd. Research show that a gd below 0.8s/f isnt audible. A softer ”knee” of the roll off makes for lower gd and more ”closed box” like sound.
I think I just grew a new section on my brain... Very good stuff... I second the request to explain some of the terms... Like for example you say: "excursion" please explain in what sense? If these videos doubled in length just to explain what you mean in some cases, your videos will be worth gold on RUclips.
I enjoy your videos. They are very informative, but your background music is too loud. Unfortunately it distracts from what you are saying. Keep up the good work.
@@HexiBase Jaybird X3 (bluetooth headphones) via Dell e5450 (laptop). Same issue here. The material and deep-dive style presentation are great on your videos, but on this one the backing audio levels are too high. Thank you!
I'm so glad I found your channel! I've also been in the market for buying a subwoofer. I make music at home and I use Neumann KH 120 "Studio monitors" But their low end doesn't even come close. I think they only go down to about 55hz or so. If I were to buy the "Matched" Subwoofer Neumann provides, the KH 805 - It's $2000 Canadian dollars... That's a boat load of money just for a sub. Worthy, long term investment? Maybe... I think it goes from 18hz-300hz with 200W amp. This is the biggest reason I'm looking into building my own. There's gotta be a something that comes at least close to this performance for a better price. I've gone down the "Rabbit hole" Of learning about subwoofers lately and this channel is an absolute blessing. Time to binge watch and write some notes! THANK YOU!! :D
Something i would really appreciate is finding out a bit more on PA subwoofer enclosure design and how one goes about tweaking it in order to get a high output for larger venues. Happy i came across this channel. You know your stuff and thats epic
Great video as always, I know i'm just one guy but i really appreciate your videos and hope you continue...The 2nd time i'd ever been in a stereo shop i'd asked this question "which was better?" which he replied "The one I said, you can buy it or go somewhere else, i ain't time to explain everything" maybe he was having a bad day, i dk, but that lead me to go home and start reseaching, im maybe 6ish years in and is a truly exciting hobby to me...knowing what i know now though, and people approaching me, i could understand how he felt that day lol...good day Pete
I concur... trying way too hard when he doesn’t need to. The content is spot on great! By adding bells and whistles to “make vid better” it’s actually having the opposite affect
you are right it all is the right tool for the right job .the lomowledge and good refrence materials you refrence are indeed done very well.i would say this is what i was 100% looking for ..indeed ,good job.. thank you.
in my last car (very small toyota starlet) i've made a ported box for 2x 15'' p1 rockford subs... with a very small port (at least...smaller than to be expected) if you'd look at it...it wouldn't seem right... but it was way louder than any sealed box i put them in before...making the port bigger only decreased output... i always measure (or try to measure) all the T&S parameters as precise as possible.. and never go with the manufacturers specs. using cheap (or at least not the best) subs and making them sound the best they can (or the best i can make them sound) is one of the reasons i love audio :)
*YOUR BACKGROUND MUSIC IS FAR TO HIGH IN VOLUME AND AT THAT FAR TO BUSY - THEREFOR IT MAKES TRYING TO DEFINITIVELY INNERSTAND THE LOGISTIC - IE: HEARING YOU, EASIER!*
I was in a stereo shop and asked the salesman what the frequency response of a particular driver was, which happened to be a woofer. He responded with," flat, 20-20k"?? I looked at him completely puzzled for 5-6 seconds, turned around and walked out of the store. All salespeople need to watch this video before shooting off their mouths!!
Thanks for the breakdown. You're an angel of knowledge among a sea of quick buck wolves. I am buying a DATS3 next week and getting baselines on a few old drivers I have laying around. I can't wait to follow every word of your advice on getting some use out of them
Good information. Call me trial and error for years. I've done them all. Sealed, ported, bandpass, 4erd order, 6th order, passive radiator, open and infinite baffle. I like the extreme lows without limits and distortion. Hard to come by. But with that preference infinite baffle is the winner. A 4 way sound system will capture all the frequencies. To many subwoofer systems have no way of getting to single digit frequencies with prefab enclosures. They miss on the low lows.Infinite baffle or a large sealed box that is larger than the speakers vas as you said is something builders need to try. And of course chose large subs that have the ability to do this design. You've been in the game a while, try it.
I have some vintage 12" 3-way Sansui floor speakers with duel front ports, box tuning is 58hz. They lack very low bass, but when turned up they reproduce the sound of a live drum kit like nothing else I've heard. You would swear there is a drum kit in the room. So ported can sound very accurate as well.
Thank you for actually explaining the technical aspects of this subject! The only language I understand is facts and this video has solved my problems with trying to learn about the real difference in the two designs. Thank you so much!
I could listen to people who speak at this level all day.

With my 35$ headphones it sounds just great! :P
with my $10 DIY speaker, his voice sounds crystal clear
on my 2$ diy no enclosure speaker system i can hear his voice clearly once i ran the audio signal trough my urei 1176 comp and ssl eq
With an iPhone speaker, I had to learn lip reading.
There was music? Didn't notice it. Was too engrossed in the topic. Had to check the video again after reading this comment!
I bought a 2x12 inch ported sub quite a few years ago, and i listen to music in the high bpm range (180-210) and i could for the life of me never understand why the base was lagging behind the melody. I thought it must be something wrong with my stereo/monoblock setup, i had a few suspects but i never could figure it out, or as the local professional car audio was pretty much unapproachable i never got an answer until now...
Top tier editing, knowledge and presentation. Bro. Great material.
Please either turn down or remove the annoying background music. You are dumping a lot of info at a high speed and it is super distracting. Thanks
yes!
shut up and listen
I agree. I cannot concentrate on what he's saying as the music is the same level as his voice for me. I love music but not while i'm trying to listen to technical info. I wonder if HexiBase would re-upload this without the music.
Agreed. I love the content and info shared in you videos, but the background music level is a bit high and distracting.
Watch it again whiney prick. Watch it enough times till your slow noggin gets it. The music was good.
I Christen you Dr. Hex. Keep spreading the light. Great job. Love the whimsy along the way.
Thank you for sharing all your knowledge with the world. You are like the Einstein of sound. I wish you were giving classes near my town. I would sign up for all of them. Keep up the amazing work !
I just went through this decision process.. I bought a SKAR EVL-10 D2 to be run with my Rockford Fosgate 1200D1 Prime.. It is in my 2012 GMC Sierra extended cab. The only space I had to use is where the jump seat used to be in the middle of the front seats. Specs for the sealed enclosure allowed me to build my box and mount the original armrest on it.. I am extremely happy with it as I am more into the SQ anyways.
I remember when I worked at Circuit City, I just wanted a simple single 12" sub and the employee discount was pretty much %50 in car audio. I grabed an MTX Blue Thunder Legend 12" and the specs said 1 Cubic foot for sealed so I grabbed a simple 1 cubic ft sealed enclosure.
My god, you would have thought I took a dump right on the floor. "Oh no, you need a bandpass box", "you won't get enough bass" etc. I stuck with the sealed and threw a simple 250 Watt RMS amp and a crossover on it and placed the box about 2.5 feet from the back hatch in my 280xz. That damn thing was too much bass in that car. All they could talk about the next day was how much output it had in a hatchback. I don't think they really knew much about acoustics.
Yeah sealed will work better in a car. You just don't need the extra output/efficiency of ported. Also ported has gain down low so unless you EQ it, I'll be too bassy and boomy
Hatchbacks just sound better
yo yo, an old school enclosure junkee here. Bobby Gately and MBenclosures are my homies. The former is local to me, and i watch MB, so much might as well l know him!!! Bobby moved me to the"ported side" ,after years being exclusively sealed. Ant Hex, thanks for dropping enclosure knowledge, I like it very much
Usage is what matters. There are no competition sealed boxes.
Damn this man is well spoken and his analogies are profound in a way.
Excellent. Concise, correct, quick, and clear. THANK YOU.
Indisputable.
Personally I just say; there are good and bad versions of both!
All speakers are a compromise and every design has pros and cons. But if you’re an audiophile and prefer quality over quantity, and want accuracy, good transient response, smooth low frequency roll off, good power handling and cone control, and a practical sized enclosure(especially in the tight confines of an automobile) then a sealed system is the logical choice. The better sound quality will far outweigh the few dB of efficiency you are sacrificing. Besides, amplifier power is much more affordable now. I love these videos. Finally someone that speaks my language. Keep up the great work.
for me by the time power compression and the distortion that comes with it kicks in, your better better off with a low tuned ported tuned just slightly below fs (like 20hz for a 25hz fs) this pushes the sound of the port into a faster slope thus eliminating it earlier, also by the time you hit 40 hz your out of the group delay region and we generally cant hear it below that mark. you also avoid the added delay of an eq that your sealed needs.
I like the large and low tuned design myself and found over many years have building and experimenting that that works the best. I tuning frequency of 8 Hertz works out well for handling all the frequencies above 10 Hertz with a minimal group delay.
Thats why im building my own box and learning as much as i can but i have learned alot more from your change then most other please keep bringing the knowledge

Have to admit, I do like fact based videos over someones opinion of why they like a particular sound, or why we should agree with their choice. This was a straight up you make your own decision.

CLEARLY hes stating that Dodge is superior...
lol, GM, no matter how many times I hear that it always makes me laugh 💩
Great detail to this :D.... people used to tell me for cars, "Sealed if you want punchy tight bass, ported if you want more bass extension"
I agree with others on the audio mixing, but your content is phenomenal. Keep up the good work, man! Thanks.
Learning and playing around with WinISD was a gamechanger for me.
As an FYI, I had no issue focusing on your words over the supposed “loud” background music. No issues here.
I forgot about most of the info about ordered enclosures from my car audio days from 25 years ago. Thanks for the reminder and great video. 🤗 🔊
1:54 This lends to an interpretation of the source material. If you've ever listened to a track at 0db gain in the bass region (which I know you have), it can be very unrewarding. At this point we become the mixer, and decide where the bass should be (as well as the other Hz if you have the ability). I feel like +6db bass is not out of character for the original intention of the song in many circumstances.
And that’s why one should be careful and watch that clipping indicator when listening to regular music (more specifically rap with the amount of distortion, +6db peaks, tryna play 2 frequencies at once to name a few…
I ported a home made cabinet that was used with a 15" EV for a bass guitar. This cabinet covers my high end, and I use an18"CV for my low end. I hit the library to learn how to tune it to 50 hz. If the volume or tone were affected, the effect was miniscule compared to what the amp does. But I can say for sure that the port made it much more responsive to the volume variations of my touch than it previously had been, and the freedom of motion of the speaker allows much better sustain.
Sealed subs require more power and more excursion to reach the same spl levels as their ported counterparts. More power + more excursion = decreased linearity and so more distortion. The only advantage to sealed subs are lower extension (think 10hz below) and size. In a low tuned ported cab the driver will sound the same above 30hz (music region) than its sealed alternative!
Please do a video on Aero Ports! Baffles, no baffles, side/baffle/front/back mounted port, port opening in relation to subwoofer location, port center vs corner, adding bends to achieve length without having port hang out of box etc. That would be awesome!
Your channel is criminally underwatched. I thought I knew a little bit about audio but you keep making me realize just how much I do not know. Don't even know where to start to learn all of this. Fantastic work!
WOW! And here when I first started to watch this I was already prepping my "but the laws of p[hysics!" reply as few people accurately describe the blurring/ phaseshift/ delay.... produced by allowing the back of the speaker's accoustic energy to enter the listening room. But you even provided a graphic showing it!
Now my Maggies however....
I will be checking out more of your stuff!
From my experience the sealed enclosure gives you a much more solid sounding bass than the ported box. Ported boxes sound boomier.
I personally don't hear the difference outside of the vehicle, but inside I agree, it's definitely more solid.
True that sealed enclosures can have "tighter" bass, but some well reviewed ported systems (such as those by Ohm Acoustics) have received high marks for their tight bass response. One of the (claimed) advantages of porting is to have as good bass as sealed systems but in smaller enclosures.
I have 8inch subs with port id compare them to 12inch subs in closed box mine sound smoother but my friends more thumping but distorted in a way were both running 500watt not much but were budget builds id do ported most the time as long as the ports right but ive seen them done wrong with over sized ports that couldn't do tight bass like my ported box
@@toxictophat711, exactly correct. A smaller woofer will give tighter bass and mid bass. But a larger woofer can give deeper bass. Ideally, porting or using a passive radiator (drone cone) is sometimes better than a sealed woofer. With ports, the size of the opening is critical to good sound. Lots of choices but I prefer tighter bass to deeper bass that's muddy and boomy. That ain't hifi and just sucks. Fuhgeddaboudit!
@@martyjewell5683 The common misconception that a smaller driver produces "tighter" or more responsive bass has been debunked time and time again. I wasted a lot of money when I believed that by buying many 10" woofers as opposed to one 15".
Didn't realise the channel was back. Good to see ya
Please don't laugh at my channel. I'm not trying to be you, just trying to enjoy myself :)
Man the knowledge you drop in me ever time is amazing. Thk
Thank you for another very informative video. I'll watch it several times in order to digest everything.
I LIKE THAT YOU SAY CHEERS
I'm all about bass so I'm ported
If you don't know how to use the ports to adjust your frequencies then you have something else to learn!
And then there is the transmission line. Technically ported but with a twist. I have yet to build one but it is purported to something of a middle way. Since there are so few really good drivers available these days with a Qts suitable for sealed use (at least in home stereo environment) it may be a way to get decently clean bass with lowish Q drivers.
One matter you did not cover, that I would love to hear your take on. All bass drivers entail certain physical and electrical properties that make them a good fit for either a sealed or a vented alignment. Regarding vented alignments, I find that the size of the vented box may vary greatly. For example, given two 12 inch bass drivers for vented enclosures, one may call for a very large box volume whereas the other may call for a much smaller box volume. Assuming the two bass drivers are of equal quality, I have found the listening experience of these two bass driver systems to be radically different, the small box version sounding very stuffed and muted, and the large box version sounding very full, airy, and more natural (like real bass instruments). Unfortunately, manufacturers of subwoofers steer clear of large vented alignment systems since the very large boxes would not sell with the general buying public. So all that anyone sees is small box systems, either sealed or vented. I find the large vented alignment systems (and I have built over a dozen of them) are very pleasing, whereas the factory sub woofers always disappoint by comparison. Something for folks to think about.
Without experience or expert knowledge i have an feeling for what you're saying . a large ported box definitely sounds better. I think its industry jargon used for selling points. Like most experts they impose their knowledge over the persons listening reality.
On the other hand, if most people will not accept a pair of very large boxes (2-3 cubic feet each) in their listening space, then I guess it doesn't really matter how much better they sound vs small box systems. I actually feel the same way about extremely expensive electronic components. The amp or CD transport or DAC or tube pre costing thousands each may all sound better than my @ $500 a piece components, but since I am unwilling to spend that kind of money on my components, then it doesn't really matter if they sound better.
I like it when clients become experts because their buddy or a auto glass shop recommended an enclosure. Only to be blown away by a sealed or ported enclosure they didn't' expect to sound the way they wanted. Sealed or ported? Yes.
Sealed subwoofer box is the best way to go . Clean Hard Bass
For my front speakers I am using the 18" GRS 18PT-8 in a 4 cubic foot sealed enclosure it can go 3db down at 41.6Hz. It just sound is incredible. But for the subwoofer I use ported and use it for frequencies just below the GRS based speakers. When using the ported speaker for a subwoofer at frequencies that low you will not be able to tell any effects of slower transience.
In a car I prefer the softer and more boomy sound of a ported enclosure over the harder and sharper sound of a sealed enclosure.... in the house I prefer the exact opposite but with a larger cone diameter that would be unrealistic in a car... but only when I'm listing to music, if it's for movies & TV, small sub in a sealed enclosure so the sound can keep up with the action... that clears everything up... right!?
That really made no sense.
Ported boxes arent softer (boomy maybe I'd poorly designed) and sealed boxes are not 'harder' or 'sharper'.
Im really not even sure what you're trying to say with that description.
Your presentations are so low key. If one doesnt really tune in, its easy to miss something. You present clear concise extrapolations on the topic. Thank You. Liked and Subbed.
Or you could go with sealed with a passive radiator. Offers more tuning options and eliminates possible chuffing noise from ports.
But big ports dont cuff
Every time I have been "wowed" by a home system, the Sub was running a passive radiator. SO I have come to rely on them for my own stuff, far easier to "tune" and to my ears, far better sounding...
@@skyoptics ... ALL ports create secondary wind noise... Unless they are so over sized, that you might as well be holding the woofer in your hand, for all the good the box is doing.
Love your videos about woofers & boxes you make things understandable for us noobs & I'm sure with all these informative videos I'll be able to make a really good enclosure soon enough, I've made some that work really well but never really had exactly what I wanted
Awesome, I'd like to know what education you had to bring you to that level of understanding. Couple of quick questions, does a enclosure with two drivers have to have a divider? What is your opinion on using poly fill in enclosures? More videos please! Watching / Learning from Virginia.
@@HexiBase the reccomendation of mineral wool made me pause...correct me if i am wrong, but it is a very dangerous material to work with
www.bing.com/videos/search?q=mineral+wool&docid=608025939454722974&mid=B57934B61B48A24B0973B57934B61B48A24B0973&view=detail&FORM=VIRE&PC=SMSM
With a similar driver. An optimally designed ported enclosure is actually comparable to 3 closed at the frequencies where the port is active. Such a enclosure produce way less distorsion due to the lower cone displacement (assuming an optimal port), at the same spl.
Under the resonance frequency closed are more efficient.
The difference between the different enclosures are mainly group delay. Reflex boxes having higher gd. Research show that a gd below 0.8s/f isnt audible.
A softer ”knee” of the roll off makes for lower gd and more ”closed box” like sound.
I think I just grew a new section on my brain... Very good stuff... I second the request to explain some of the terms... Like for example you say: "excursion" please explain in what sense? If these videos doubled in length just to explain what you mean in some cases, your videos will be worth gold on RUclips.
i LOVE the Amazon delivery interlude.. =)
I enjoy your videos. They are very informative, but your background music is too loud. Unfortunately it distracts from what you are saying. Keep up the good work.

Can you turn the music up just a bit next time, i can still almost hear you
I'm so glad I found your channel! I've also been in the market for buying a subwoofer. I make music at home and I use Neumann KH 120 "Studio monitors" But their low end doesn't even come close. I think they only go down to about 55hz or so. If I were to buy the "Matched" Subwoofer Neumann provides, the KH 805 - It's $2000 Canadian dollars... That's a boat load of money just for a sub. Worthy, long term investment? Maybe... I think it goes from 18hz-300hz with 200W amp. This is the biggest reason I'm looking into building my own. There's gotta be a something that comes at least close to this performance for a better price.
I've gone down the "Rabbit hole" Of learning about subwoofers lately and this channel is an absolute blessing. Time to binge watch and write some notes! THANK YOU!! :D
why I have't found this awsome channel when I've got nothing to watch?
Something i would really appreciate is finding out a bit more on PA subwoofer enclosure design and how one goes about tweaking it in order to get a high output for larger venues. Happy i came across this channel. You know your stuff and thats epic
Dude. Great channel. Keep this stuff up!
Dude I love the mix of you (brilliant) humor and the huge amount of knowledge you share in such a short video
Please fade the background music.
Great video as always, I know i'm just one guy but i really appreciate your videos and hope you continue...The 2nd time i'd ever been in a stereo shop i'd asked this question "which was better?" which he replied "The one I said, you can buy it or go somewhere else, i ain't time to explain everything" maybe he was having a bad day, i dk, but that lead me to go home and start reseaching, im maybe 6ish years in and is a truly exciting hobby to me...knowing what i know now though, and people approaching me, i could understand how he felt that day lol...good day Pete
Please no music or what ever is in the background.

Could you do a video of bandpass versus ported?
you are right it all is the right tool for the right job .the lomowledge and good refrence materials you refrence are indeed done very well.i would say this is what i was 100% looking for ..indeed ,good job..
thank you.

Your music was so loud I had trouble understanding what you were saying.
so true, i realy like your content, but it's so hard that i rather like to switch
Yeah right! It's not the complexity of the subject material, blame the music! LOL
That's interesting. BG music in other videos often distracts me. This didn't sound loud or distracting to me whatsoever.
in my last car (very small toyota starlet) i've made a ported box for 2x 15'' p1 rockford subs... with a very small port (at least...smaller than to be expected)
if you'd look at it...it wouldn't seem right... but it was way louder than any sealed box i put them in before...making the port bigger only decreased output...
i always measure (or try to measure) all the T&S parameters as precise as possible.. and never go with the manufacturers specs.
using cheap (or at least not the best) subs and making them sound the best they can (or the best i can make them sound) is one of the reasons i love audio :)
Can you explain 4th order and 6th order how you calculate them
Bandpasses* please and thank you
This is SMOOTH spilling of knowledge
can you do a video on 4th order and 6 th order ?

I was in a stereo shop and asked the salesman what the frequency response of a particular driver was, which happened to be a woofer. He responded with," flat, 20-20k"?? I looked at him completely puzzled for 5-6 seconds, turned around and walked out of the store. All salespeople need to watch this video before shooting off their mouths!!
I listen to your video in 0.75x speed.
Thanks for the breakdown. You're an angel of knowledge among a sea of quick buck wolves. I am buying a DATS3 next week and getting baselines on a few old drivers I have laying around. I can't wait to follow every word of your advice on getting some use out of them
Love the relentless puring of knolwedge, I'll show this video when my sons ask me, "dad, what is an expert?"
I thought you were going to say when he asks you about where babies come from.
Im about to start making my box im glad i came accross this channel, Thanks a mill for the wisdom!!
Good information. Call me trial and error for years. I've done them all. Sealed, ported, bandpass, 4erd order, 6th order, passive radiator, open and infinite baffle. I like the extreme lows without limits and distortion. Hard to come by. But with that preference infinite baffle is the winner. A 4 way sound system will capture all the frequencies. To many subwoofer systems have no way of getting to single digit frequencies with prefab enclosures. They miss on the low lows.Infinite baffle or a large sealed box that is larger than the speakers vas as you said is something builders need to try. And of course chose large subs that have the ability to do this design. You've been in the game a while, try it.
I have some vintage 12" 3-way Sansui floor speakers with duel front ports, box tuning is 58hz. They lack very low bass, but when turned up they reproduce the sound of a live drum kit like nothing else I've heard. You would swear there is a drum kit in the room. So ported can sound very accurate as well.
@@HexiBase Makes sense.
We’re not worthy!!! Been a fan for along time. Keep it up and give Sophie a high five from me.
Thank you for actually explaining the technical aspects of this subject! The only language I understand is facts and this video has solved my problems with trying to learn about the real difference in the two designs. Thank you so much!
