I am a channel that is generally orientated around videos to do with speakers and audio. I make videos about speakers (such as bass tests, tear-downs and more), and I also rebass and bass boost high quality music without any distortion.
• I do not own the rights to any of the original songs posted on this channel - I only modify bass notes to be different frequencies, or simply much louder without any audible distortion. ❗ If you would like a video removed, please email me first via my youtube inbox before copyright-striking the video ❗ - this is a much easier and faster process, as I will take down songs on any requests from the original artist or record label - Thanks in advance 😊.

Done this for twenty years and that is one of the most dead on common sense language breakdowns of the process I have seen. Great vid!
Hands down - this is the best box design video I have ever seen!
I agree, very detailed and understandable
Yup very helpful, always looking fir info on how to tune a box and this clarified a lot fir me
I have been building boxes for years but this is one I didn't know thanks very much man now I know how to get them to play really low the 1.33 I would have never thought about you are awesome
Just an error correction regarding Decibel:
3 DB = 2x
10 DB = 10x
13 DB = 20x
16 DB = 40x
20 DB = 100x
One Bel (decibel = 1/10th Bel) always multiplies your origin value with 10 and it is used for setting values into relation. For example antenna gain. An antenna can gain up a signal of one millivolt to 40 millivolt. That's 40 times in relation to without any antenna at all.
How often does 10 db fit in here?
1 time, because to fit twice the signal has to be 100mv. And from here you go in 3 fb steps.
0db = 1mv (in relation to the original signal)
10db = 10mv
13db = 20mv (bc additional 3db =twice the value)
16db =40mv
So many text for nothing, but I hope my example can help a little bit in understanding.
Ah, btw:
In acoustics (volume, SPL, sound pressure etc.) the relation is set to the faintest sound a human can hear. Don't ask me what the unit/term/formula for that sound is. Maybe someone can Google and post the answer here. I have to go to bed now.
Have a nice Easter everyone!
It's actually even more fun than that!
While it is true that a 3dB increase is equal to a 2x increase in power, the actual amplitude (in the case of audio, the distance the driver physically moves) of the signal is only increased by the square root of 2! Anyone familiar with square roots might notice that this means a 6dB increase is required to double the amplitude of a signal, as √2 × √2 = 2. This is the same as 3dB + 3dB = 6dB.
But wait! There's more!
Humans generally don't perceive stimuli linearly: simply doubling the power (or amplitude) doesn't mean we see the stimulus as twice as strong! In the case of audio, this relationship is heavily dependent on frequency: we may be less sensitive to lower frequencies than "mid-range" frequencies, but we are much more sensitive to *changes* in volume at lower frequencies than mid-range frequencies.
As a rule of thumb, to double the perceived loudness of a 1kHz audio signal, you need an increase of 10dB: 10 times the power! However, down in the bass region, a doubling of loudness requires an increase of only 4-5dB or so: roughly 3 times the power. For anyone interested in learning more about perceived loudness, look up equal-loudness contours: there are actually several common sets, and because it's technically a subjective measurement, the exact numbers involved will vary from person to person.
Decibels and biological perception are confusing topics, very easily misunderstood and mixed up, and also fascinating when you think about them. Did you know there's not just one meaning of "decibel?" Depending on the context and measurement, there are different uses of the term! At its core, a decibel is a relative measurement where 0 dB is equal to "times 1", but in audio you'll frequently find "dB SPL", which is an absolute measurement of the energy of a sound, or "dBA" which is similar, but biases the measurement such that frequencies we're more sensitive to count more than others. "dBm" is an absolute measure of power, "dBV" is an absolute measurement of voltage, and so on! So while the loudest an amplifier might go is "0 dB" (meaning no decrease in power from its maximum output), that same output can also be measured as some very high (100+) dB SPL (how much pressure the driver is producing), or even db SWL (the power being put out by the driver)!
@@tavaresa13 thank you for your excellent addition to the topic!
The nonlinearity in human perception of loudness is BTW the reason, why audio preamps have a logarithmic potentiometer for volume control (in case someone didn't know).
Have a great time!
@@tavaresa13Yea sound perception is a hard thing to measure. There’s no absolute standard just estimates and rule of thumbs.
Thank you for the WinIsd 101 tutorial, and all the helpful information required for designing a box
I just got started with winISD and this is a great video to get you started and not hung on the ropes! Outstanding!
I built a massive slot port box to spec for a 15" L7s a year ago for 28hz and didn't realize the port volume was a little too big for it, the bottoming out sounded horrendous lol. learned a biiiiiig lesson making that thing haha great video.
Amazing video man, now we would love to see one on sealed enclosures thanks
this is best sub box design video out here on youtube
idk about that for sure but thanks man!!
I followed the instructions in this video, and made a home sub for Sundown audio x12 v.3. Plays clean at low volumes, hard and deep at high volumes😏 and has a very good freuqnecy response. and looks alright too. Recommended
One of the best and most complete breakdowns on design and tweaking of a sub box I've seen yet... Nice job...
This is the comprehensive and detailed video I've been looking for. Thank you!
Winisd sure helped me in my enclosures I built back in the day. Great video.
I appreciate the video. I’m new to subs and want to do it RIGHT. It’s nice to know a couple tricks but I’ve noticed sub placement, wire quality, OFC or CCA, the amp the radio the OHM the voice coil the box just so much to go into it. And something like even improving wire quality makes a noticeable difference, now I know if I do all of this right and well then these noticeable differences will turn into MASSIVE differences. I want rock hard deep bass that serves well in all areas but also I really want amazing quality, it feels so good to feel GOOD punchy bass rather than just punchy bass.
Your video is a life saver, made a 25hz box, for my 1500w woofer and it plays lows so good. Thank you for this video man!
Built one like this for an AB1244 like 4 years ago. Played 25hz like a champ and rolled off quick after 80hz or so. Not flat output by any means, but adding a bit of deadener to the back and side walls brought a nasty 34hz peak down by 3db.
Good tutorial on this, BTW.
This guy so late lol 🤣 them ABs love them lows
My XFL 15" can play down to 15hz in the 32hz enclosure. The sunroof just about flies off. It rolls off fast after like 70hz though
Sound video. I am planning a sub, sub for my hifi using an old car sub. Good to see someone else thinking the same ideas. Using winisd is the key I needed. Many thanks.
U have no idea how awesome this is! Thank u so much for ur knowledge u shared. Very appreciated. I just got a sundown SA 15. 👍
you sir, just earned a SUB, damn bass NERD! i love it!!!
No questions this is the most badass video on RUclips for building a box, funny thing is how I found it after I built mine, I happened to use sub box pro and it turned out really good, one problem I found was finding take offs for your internal 45s, soo I ended up taking them out with my sub displacement. If your could provide that and how to factor them into your box would be cool. I’m running a 12” Fi 4.11 fully loaded 4-5000 Rms and it fucking slams!
Great tutorial I hope I can finally design a home sub box for my new theater. Really looking to go between 15-18hz. Thanks for sharing.
This video made my day. Thank you so much for the detailed info.
Superb! Well done. Clear, logical instructions.
also all 90 degree turns in the port lowers ur tunning usually 1 turn = 1hz lower so your box could be tunned to around 17hz (but i think its gonna be around 18-19hz u can find it out by checking on what f the sub has smallest excursion (i hope you understand)
Award Winning video IMO! This is what you do if you want really DEEP bass.
Did this technique for my JL 10 and had to use several feet of 3" flexport as my port was tuned so low to get the right response. Essentially a coil of port tube in the enclosure tuned very low. Requires a high power amplifier to get the excursion needed to make it work; but sound is amazingly DEEP and not the boomy duff duff boom-boxy sound.
Even without the DSP controls, the enclosure is well behaved and not boomy.
Have to roll the windows down to get the extremely low frequency stuff out. :)
A single 3" port for 10" subwoofer...? That models to.. oh my.. 76 m/s (!!!) of port chuff @ 22 hz @ 450 watts... for my 10" subwoofer.
Really great quality content Chriso. Keep up the great work.
Thanks dude!!
Tnx for the info sir. More power
@@chrisosbass1286 can I pay you to design a subwoofer box. I'll cash app you If you could. I have 1 skar audio vxf 15
@@thetruthtings1672 you got this awesome video that gives you all the knowledge to do it yourself!!
@@BabyBlue.23 nope I'm lazy can I pay you to design me a box since you replied and he didn't
Great video. Thanks for all the details. One thing I didn't find was the length of an aeroport
Very helpful video. Thank you !!!
Great vid on box building!
Excellent explanation !!!
The real deal tell all video. Greatt greatt video. Keep up the good work Chriso.
Very good! Congratulations!
Great video. Abridged text version: Increase the size of your box approx 1.5 times the mfg suggested size and lower port tuning. Doing so will kill 3-5db of total output so plan on doubling power, adding another woofer or both to get the output back. The engineering acronym never changes. TANSTAAFL There Ain't No Such Thing As A Free Lunch. These days power is ridiculously cheap so power up and let em slap!
Great video! Thanks!
Very informative. Thank you
Love the Disclaimer . Honesty = respect
Great stuff love what you have provided. Curious though, in the beginning you were touting round ports. Then you seemed to favor baffle type
Outstanding video! I'm about to build my first box. Pyle gearx plg64. (6.5 "woofer") lol
Thanks for the information 👍
Great video, so many of my questions have been answered. For me building a box was never difficult it was tuning it to my speakers is where I struggled. Your video truly helped me understand the info I was missing and I appreciate you also sharing the math with us. Well done my friend 👍🏽
The problem with all these super low and loud subwoofers in a Home Stereo is that while it's playing at moderate levels, I keep hearing a Helicopter, Big Truck or Loud Muffler Car outside my house. I run to look outside but nothing is there.
I think that’s called schizophrenia
@@deadcow59 Heh Heh. But, no schizo. The good stereo system with the good bass is hooked up to the TV. Sounds are revealed that would normally be missed, and many of the sounds are "Thrown" . ... I'm surprised now how much I hear a Bass Drop. Even in TV commercials they use a Bass Drop.
Respect!👍
Fantastic video!!!!💯💯💯
I usually start with Winisd and then I use Torres to get my box size and tuning. After that I go into SketchUp and model the box so I can factor in all the port bends.
where you can get torres
Would like more videos like this as nobody get good results. 👍 So much MORE need to know but good luck and thanks for videos
Very knowledgeable video it’s great 👍
Great info bro...thanks....
Great informational video. I have a couple questions about using my Skar zvx 18s and which application is best used for a Mac
the best tutorial on YT for a sub design, Can you do a video for a DIY Home Theater Sub box. Do you do project design? would like to get your contact details, if its possible?
Nice it was something i needed thx
no problem!
the best video on youtube awesome 🔥🔥🔥💪👏👏👏
This video was the most informative and easy to follow!!!, I assume that adding a filler, like polyfiller, or insulation helps when there isn't enough space for the optimal enclosure size, But is that the best way too solve less area!!??
good tutorial.ty
I love this video its so informative. Could you make a detail video on how to use the Torres Tuning Calculator?
Really great box design video!
Just wish I've seen it 3days ago before closing up my box.
Let me know if you are open to helping me out with my build?
Excellent video....and yes, Sir...never discount a bit of old skool maths and a pen and paper. Boom. 😎
amazing video, keep up with the content!
being outside America, I just got a little confused with all those imperial measures. But great video anyways!
I'm in Australia and we use the metric system but all of car audio just seems to use imperial measurements
@@chrisosbass1286 what up bro, need your help,I'm trying to make a box for 4 8inch subwoofer
excellent video and explanation, could you suggest the steps to make a box for 2 p3 D4 punch subwoofers with the port in the middle of both?
Thank you Sir. Awesome video, audio, clarity, tutorial, lessons & non condescending explanations.
I've been designing & building enclosures for 3 decades & found your methods to be a great help.
I don't have winsd but do use boxpro. Look forward to your videos.
This is a really good tutorial, it is actually just great
thanks man!
No problem, it deserves more credit.
Awesome
Thanks ❤
Great info. Going to take it and apply it to a single cab truck design. There has to be a way to get better base out of a behind the seat design box. Has any one every used tapered ports to increase velocity with out having the proper distance do to enclosure requirements?
Wow I learned a lot
I'm an engineer with an interest in making a nearfield sub for my Home cinema. I found your video extremely useful for trhinking through the process and considering the shortfalls of the software. It's not easy to find a sub for infrasonic delivery that doesn't need to play loud... so I'll make one :).
I'll watch through more of your content.
Are there any differences that I need to take into account besides cabin gain if I'm using WinISD for my cabinet design?
1:35 is wrong. Those kind of subs are made for (as you mention in the video) high Sound Pressure Levels, and often have a Resonant frequency of about 35hz. There are better options like home theater subs to get low easily. The 10“ dayton reference woofer for example has a frs of 25hz, which will make it much easier to tune it lower.
And also, you don‘t need such high power levels (like 500 or 1000W). What‘s more important is the efficiency of the sub at 1W. From there on, you can multiply the power for a 3dB increase.
E.g.: 91dB/W/m -> 1W = 91dB, 2W = 94dB, 4W = 97dB…. 256W=115dB.
E.g. 84dB/W/m => 1W=84dB, 2W=87dB… 1024W=114dB
What would you recommend for two12" subs with 400Wrms each that does not have any T/S parameters?
Nice bro
I have 2 ground zero gziw 300 - II it has 10mm xmax and 350w rms but i have a big box and im gonna try to add 2 extra walls inside the box to see if it helps with lower frequenzies
FAntastic video!
Is it worth making a low tuned box if your subs aren't really made for low lows? I'd like to make a box around 28-30hz and be able to dig into mid/low 20s ..but i was told my subs wont like it because the FS is high ?(43hz) and they are geared more for spl but i dont really know much about it all i just want those lows.
I use slot ports and like 6th Order Bandpass for single but I think this enclosure should work better for the 15" Machete Sport V2 in the Nissan Hardbody. 24Hz I notice frame resonance in the 6th Order.
Tip, learn to use Sketchup. That'll be perfect for you to draw your boxes out ;-) Great video!
New sub here
Inspiring
i have noname speaker that have no info about these ts parameters, and i know only the box dimensions, do somehow will i get atleast the speaker frequency response? it can play as low as i want, it can go 1hz (at 20hz it have ~10mm movement at 30hz have ~14mm movement and 40hz it have ~12mm movement at twoway ) its a 30w 8R speaker :)
I'm in! Low, loud bass!!!
22 minutes , listening . well worth it Bro . Loved your idea n presentatioin ...... Well done .
Boy , that was
ffffffffffffeeeeeeeeeeennnnnnnnnnnnnntttttttttttttttttaaaaaaassssssssssssstttttttttiiiiiiiiiiiiicccccccccccccccc , Mate .
Hatttttttttttttttsssssss offfffffffffffffffff to you , I will just follow the last numbers .
Will it be the same for my 2008 sedan , please ...... ???
Will all this work the same for theater subs? I have box ideas for powered subs for home theater applications, I can listen to music anywhere but I really want people talking about the surround sound I design and of course with any good action movie or whatever you really want to FEEL like you are in it,,, you really want to hear thunder on tv and think that there's a storm outside only to realize it came from the room you are in, are there settings for the size room and things of that nature? And if not are there any that you or anyone can suggest?
Question, at 19:40 when you had to make the adjustment on your box and your port didn't line up with the front of the box... when you added the 1.35 or whatever it was, couldn't you just remove that 1.35 from the end of the 3rd interior port wall on the inside? Or would that change the tuning as well considering that'd be adding space inside?
I remember when I was 16 just got my first car, a clapped out 94 Sentra. I was broke so didn't have money to just go buy a $80 box for 2 10's. My dad had alot of 1" thick plywood and I had did this same design and made it oversized not entirely knowing what I was doing at the time but it worked. I had 2 Rockford Fosgate P1's 10" woofers running this old ass kicker zr1000 amp my uncle gave me he had sitting in his attic for years was barely able to angle the box into the trunk, but man that system would hit lows so hard it felt like it was hard to breathe and would make your nose tickle. I had friends who had like a 15inch kicker or 2 twelves everything they got from the local audio shop and yea their systems were loud but more rattling than anything and my little 10s were just pushing alot more air and hitting deeper frequencies. Alot of people asked what I had and never even heard of Rockford Fosgate.
After having to extend it out which to get your area back, consequently extended the port length, couldn't you have taken it off of the third port wall to keep the same tuning? I know it wouldn't be exactly the same distance as extended considering it's adding back area. I know it gets really complicated at that point so just leaving it alone is probably the right idea going through my thought process. That being said thank you very much for this video. Clearly explains everything. When people say why do you need to know math, this is why haha
Hello! Port area should be calculated by box net volume or total volume ?
Any feelings on kerfed ports? I've heard your port starts at point of desired port area... And do flare the inside opening? Subs closer as possible to each other or further apart as possible or no difference. If port ends half way thru do you add another 90° to aim towards the baffle? My current single 18 is tuned to 28htz it slams on bass boosted music but totally flops in higher notes and starts clipping very soon.
Dosent changing the height and width of the box at that point alter the tuning because its based on the volume or does the box software keep everything where its needed to prevent the response from changing?
I built a 13 cube box 4th order bandpass for one pro fosgate 12
It was insane you could literally vibrate items off the counter at the local gas station
My friends would come out the store and say the cashier is confused and thinks it's an earthquake 😂
I used winisd to build a ported enclosure for a kicker 12 it gave me exact parameters and it would blow your doors off
Thank you, someone that speaks my language. Lol.
I got wonderful sound from two recycled 8" Andrew Jones subwoofers, push pull, in a sealed box I made with plenty of stuffed animal fluff inside, and powered by two cheap chinese class D subwoofer amps.
Thanks
Out of topic. Is it ok i use only the other terminal coil of the sub even if the sub is dvc? Or it shoul be Combine the two terminal coil of the sub either serries or parralel? Because my amp is not match for the sub ohms.
I got a question can you multiply the total net volume or you have to multiply the net volume of the subs individually
Do you have any videos focusing on band pass box builds fourth or six order?
3:44 QUESTION: Is 1.33x the manufacturer recommended net volume size of the min, mid, or max number they provide? Meaning, my 15" Fi Neo 4.11 is recommend I use 3ft³-5ft³ per sub. So do I multiply 1.33 by 3, 4, or 5?
It's important to know I will be clamping a little more than their rated power of 4500 (rated 4500 but Fi says up to 7500 so I have each sub connected to it's own Taramps Bass 8K wired down to 0.7 ohm = 10,000 RMS Watts per sub but again, I expect to clamp only 5k each). Sub's Fs is 33.6Hz so I chose 33.6Hz as my box tuning with port area of 16in² per cubic foot of net volume as recommended.
For more info and videos, see my RUclips channel for build updates which starting June 2021 will be with my new larger custom enclosure of 8.5ft³ net (4.25 per sub) whereas now (May 2021) they are in a "labyrinth enclosure" (2 individual long winding ports) and only 2.75ft³ each sub net volume and port area half of what is required (8in² vs 16in²) which both (port area AND net volume) are greatly undersized.
I have clamped 7000 each. 155.5 dB on my 2 15s no wall as seen on my RUclips channel (access by clicking on my YT photo)
When I say this video gives you all the info that you need if you need more then you should invent itYo Chris do you think you could do a fourth or sixth or video or point me to one if you have it already the information you give is awesome and understandable thanks a lot
Thanks for the feedback, that's what keeps me motivated.
I don't know too much about 4th order and 6th order box design so I haven't made a video on it yet, but here's a video that first helped me learn how they work: ruclips.net/video/HISsqb3Wh2o/видео.html . It's not too detailed and it doesn't show you everything but if you have WinISD installed you can design 4th order boxes with it after watching that video :)
I’m down to learn with you.
Just curious, I would like the port on the rear of the enclosure. How will this affect the build?
Ok so questions if I have a dvc 4 wired in parallel which drops too 2ohms and 2 of them which drops too 1ohm and 1200 watt amp I'm a building a box for a 2ohm sub 600rms or is 1 at 600 or 1 at 1200 or maybe I'm over thinking it
Good afternoon I have a question for you. Do you know what software program is used that I can put in the idea I have for Tops and subs and it would give me the best way to make speaker boxes
I've asked before but nvr got a response I have 4 skar svr12s so is 10.5 cubes good and tuned to 20hz with a port area of 11cubes per cubic ft is that ok or does port area got to be lower
Slot ports are about as aerodynamic as a city buss (the way they are commonly constructed), and should not be considered equal to an aeroport with the same cross sectional area. Which will flow much more air than a equal sized slot. I encourage you to test it. straight slot vs folded slot vs aeroport, all at the same tuning Fq.
How big do you want the box to be
Sweetdude.
