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

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 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

This is the comprehensive and detailed video I've been looking for. Thank you!

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.

One of the best and most complete breakdowns on design and tweaking of a sub box I've seen yet... Nice job...

Amazing video man, now we would love to see one on sealed enclosures thanks

Winisd sure helped me in my enclosures I built back in the day. Great video.

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)!

@@tavaresa13Yea sound perception is a hard thing to measure. There’s no absolute standard just estimates and rule of thumbs.

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!

This video made my day. Thank you so much for the detailed info.

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.

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

you sir, just earned a SUB, damn bass NERD! i love it!!!

No questions this is the most badass video on KZread 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!

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. :)

Love the Disclaimer . Honesty = respect

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 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!

Really great quality content Chriso. Keep up the great work.

I love this video its so informative. Could you make a detail video on how to use the Torres Tuning Calculator?

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?

Very knowledgeable video it’s great 👍

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?

Great video! Thanks!

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)

Fantastic video!!!!💯💯💯

the best video on youtube awesome 🔥🔥🔥💪👏👏👏

Thanks for the information 👍

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?

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?

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!!??

Great info bro...thanks....

Tip, learn to use Sketchup. That'll be perfect for you to draw your boxes out ;-) Great video!

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?

Great video, but Im curious what kind of car would fit this size of a box..

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

Wow I learned a lot

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.

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.

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

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.

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.

@@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.

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?

Just curious, I would like the port on the rear of the enclosure. How will this affect the build?

I used winisd to build a ported enclosure for a kicker 12 it gave me exact parameters and it would blow your doors off

Inspiring

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

Want to build a closed box and im a newbie please could you help with the design?

Thanks

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?

What would you recommend for two12" subs with 400Wrms each that does not have any T/S parameters?

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.

Hi I saw this thing on the Internet call the Death Box. Do you think you could build one and put it to the test and see if this thing's any good

Nice bro

Basically learn WinIsd, Good walk through on tweaking box parameters to meet xmax, decibel considerations.

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?

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

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.

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 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 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 got a question can you multiply the total net volume or you have to multiply the net volume of the subs individually

Thank you, someone that speaks my language. Lol.

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

So if I have 4 skar svr 12s how many cubes would be good to tune to 20hz n port area

Can passive radiators work as well, for super low, as ports? If yes is there any source of info on that as the freekin thorough info you have here for ports? Thanks!

So what were the measurements to make this exact box? I have one 12” subwoofer
