Top Mount Subwoofer Front Kerfed Ported Plywood Box - DIY
ฝัง
- เผยแพร่เมื่อ 11 ก.ค. 2024
- Custom-made subwoofer box for a client's JBL S3-1224 subwoofer, to be installed and fitted within Hyundai Sonata's limited trunk space height. So I designed the box low and flat. To make this happen, the subwoofer must be mounted on top while the kerfed slot port is front firing. Making the subwoofer slightly forward and off center at the top baffle where it sits.
Here are the project highlights:
00:00 - Bass Box Pro and WinISD calculated enclosure resonance is 30Hz
00:25 - FREE schematics to TinkerCad - www.tinkercad.com/things/1rmW...
00:58 - Shopping for a sheet of mighty expensive Santa Clara marine plywood. I will never buy this again. Ever.
01:40 - I doubled the top baffle so I can cut a flush mounting for the subwoofer driver.
02:40 - Upper panels were secured by glue and pocket hole screws at the internal side.
03:40 - Perfect 90 degree kerf cut! 12 kerf cuts with 10mm distance interval. "No nails" all purpose adhesive makes the kerfs bent 90 degree rock solid.
06:45 - All edges were rounded by a chamfer router bit.
07:30 - Dark walnut oil wood stain topped with clear gloss lacquer.
10:10 - Final enclosure resonance verified at 22Hz using Dayton Audio DATS v3.
I think that's it for today's subwoofer build. And of course I ended up testing the system with a 10-100Hz tone sweep and a heavy bass hiphop track at the end. I hope you all enjoy this another episode of Charcoal Monkey's DIY subwoofer boxes! - ยานยนต์และพาหนะ
I've been a sound engineer for 16 years designing speakers and building them,
Nice job Dude!
and i love the way you work it "Clean all the time"
😇🧹
That box is BEAUTIFUL!!📦😌
A work of art!!! And 22hz??? Damn!! I know that box was hittin with just that one sub!! Imagine two!! Quality craftsmanship!!
Yes sir. 😁
Man, that box is a thing of beauty. Good job!
Thank you very much! 🤩
Great looking box! Your process is well demonstrated! Making me wanna build a kerf port now!
Thanks a bunch. 😄
Duuuude, that plywood folding hack is genius, killer build.
Thanks. 😎
The bass was awesome 🔥
Amazing build. Love curve of the port
Thanks Socoro
Damn, that box is beautiful! Keep making these badass videos!
🤘
That came out fantastic.
Kerfed ports are difficult but always worth it. They beat cleaner and tighter, I think.
Aeroport assemblies and kerfed slots are super versatile.
Nice work man.
Thanks a bunch. 😄
Very strong what you do. Congratulations, I look forward to watching your videos!
Thank you so much!
I remember back in the days I purchased Pro Box it was like $150 bucks in the early 90's. Pretty cool.
BEAUTIFUL WORK
Thanks Stanley
Another badass box bro.. it should sound great.. love the kerf port and stain
🤠
Great job on the build!
Delightful on your feedback. 🥳😎
Very impressive craftsmanship
Thank you Gopaul. Cheers! 🤩 🥳
Very good...
The colour is very natural...👍👍👍
Thanks mate
That's sweet! You do excellent work bruh !
Big up 😁
Very well done...! I like the individual little all thread terminals you just drill though the wood better than the ones mounted in plastic.
Cool, thanks
awesome work man
Thanks very much. 🤓
Good job.. 👏👏👏👏 what catches me here is the proper set of tools..
📐🔨😁🤘
Trabalho maravilhoso!! Eu não sabia que poderia se fazer uma curva em material folheado porém, peguei a manhã!! Parabéns pra você !! E o teu cachorrinho arrumou uma amizade de 4 patinhas 👏👏👏 adorei.
Thank you very much, Carrado. I am mighty glad. 🤩
Ur a beast bro... Mad props...
Best box yet. Thanks for sharing. That Makita table saw seems to cut very well.
One thing I don't like about the MLT100 is its guide fence. Vert flimsy and very unstable.
@@chrclmnky
Most of the saws that are not contractor saws have this issue, regardless of brand name. I'm in the same situation. How do you get the panels so straight?
Nicely done. I have a pair of that same JBL subwoofer I plan to have a box built. I'd like to get the same low range into the 20's. Gonna check out some more of your videos
Thanks. 👍😎
Que qualidade magnífica , seus projetos são incríveis parabéns 👏🏻👏🏻👏🏻
Muito obrigado 😎
Wow.... I just witnessed perfection.. wish i could afford this..someday
Someday
Nice job cutting the radius. Also I like using the kreg pocket hole jig. Oh and I like the hex head fasteners for the sub. Good job. 👍
Thanks. 👍💪😍
Good work👍🏾
Thanks. 😁🤩🥳
Its looking cool
Many thanks, Ashwit. 😁
Nice work mate she's a beauty

thumbs up'ed for the happy dogs!
👍
many times I have seen this video. because of your video I bought 2 jbl stadium 1224 (this type is available in my country). make a box using boxpro, but the results are not as good as the Llyod-burst song you played. thank you for your inspiration.
Thanks Rainold
Buen trabajo
Wonderful....
Love from Bangladesh ❤️❤️❤️❤️
Thanks brother, cheers from the Philippines
Exlent bass bro we good job

Master is back
You are great bro
Hai from India 🙏😀😀😀
Waiting for bandpass and tower speaker box bro
Thanks Matt.
Ayus na naman!
Excellent
Thanks a bunch Arjun
Great looking enclosure! Shame to put such a large hole into it for a terminal that's going to leak a good amount of air & would certainly prefer a drilled hole just large enough to squeeze the speaker wire through & add a little sealant to.
Also, the recessed loading of the sub is a real nice touch & one you rarely see, unfortunately!
Thanks for the vid!
Every thought of doing flat packs and sending the world wide , I will take one 🇬🇧
Good idea. Might consider that. Thanks.
@@chrclmnky well if you do please let me know
Very good
Thanks
I like it!👌
And I subscribed.... Thought I already was.
Thanks very much, James. Cheers! 😄
@@chrclmnky ✌✌
I cam close to this for a memphis MOJO 15. it looks like a joke but dose the job well. at least until I do it again with 2 15s. this video is inspiring.
nice to hear. thanks for the feedback. go build subwoofer boxes patiently, and keep focus.. and be precise.
Ganda ng box
😃
I am in India I was very impressed your all videos best👍🤙🤙🤙
Thank you so much Vinayaga😀 cheers from the Philippines!
@@chrclmnky how to buy your products anyway??? My friend?
@@vinayagatvserviceporulur4635 I hope I can ship them at no extra cost but shipping something to India is very expensive.

Parabéns ao profissional pelo capricho, dar gosto de ver 👏🏼👏🏼👏🏼👏🏼👏🏼😍🔊
Thanks a many. 😍
Supper 👌👍
Thanks 🤗
JBL Speaker and Manufacturer Home Made Box It's Very Very Recomended, The Voice Bass a Racing HOREGGG ( Indonesian Version) Excellent & Impressive 👍👍👍👍👍😉😉😉😉😉
Thanks for sharing and glad you like it. 🤩😁
i like the look of kerf boxes compare to a regular slot port. it looks highend specially when the box is stained
Yes sir. I follow box builders like Pete Bass, TC Designs, Next Level Fabrication, and they kerf boxes no sweat.
It's fancy lol
Amazing tool
Nice

This project is also awesome!!
Could you please do one project.
How to convert old 2.1 Creative SBS (Two speakers and one Subwoofer) to single compact vertical tower speaker.
I want to convert it, but lack of knowledge in this area.
Yes, soon. Thanks.
Ei Bruh this is sick love it
Thanks for the feedback. :)
Todo muy bien pero al final pusieron una pista de audio el bajo que se escuchaba no era del bafle que se había construido.
Que ventajas tiene el poner el subwoofer en la parte de arriba ?
Ништяк запилил !
Wish I paid more attention in wood shop...LOL!
😂
Me too
Awesome
Thanks Sul
Wow
How did you do the the double front baffles ?
The inner baffle is the diameter of the driver ?
Im new to all this
Hello emamdee, the inner baffle diameter is the mounting diameter of the subwoofer while outer baffle is the subwoofer outer diameter.
My Konzert KW880M is tune around 30 hz :)
Hi! I'm still a noob in speaker design and not even a native English speaker. I have in plan to buy the same speaker due to its performance and linearity. I already did a bunch of simulations, and I come with a box that has around 3.53ft^3, tunned at 24Hz, and a very flat response. My question is: is there any reason you chose 2.218ft^3 other than space? What about air velocity (I have a max at 28m/s)? But Cone excursion? Mine is excited at 13mm - 500W, but I don't plan to use it at this power. At 400W excites 12mm at 21.5Hz
Hello Damian, you have done a good work on your enclosure simulation. I should have turned this one at about 30Hz for a balanced response but somewhat miscalculated the port area that is why the overall tuning ended up way lower which is 22Hz.
What are the dogs fighting about? 😂
Just horseplay time. 😆🥳
Top 👏👏
✌
кайф вотет басс улёт аж мурашки по всему телу пошли
😆
I just watching the video and i can feel the shaking in my leg
😁
Excellent video as always! Nice test in the end please do more tests like these its kind of fun to see them go that low. Are these subs actually capable of going that low? like Down to 20hz?
Many thanks. This JBL has a factory 28Hz free to air resonance and I calculated the box to be lower than that. Exactly about 25Hz on Bass Box Pro 6 calculation but actual impedance verified by Dayton Audio DATS v3 shows 22Hz. That's 3Hz lower than calculated values.
@@chrclmnky Wow thx! Keep these videos coming bro 👍
Super voila xe qui nous manque en france
If shipping to France is just cheap, then I can build you guys awesome car subwoofer boxes.
what was that bass track you played for the sweep, and then after?
Titles are displayed.
Nice one bro im a subscriber since 2016
I do car audio too 🙂
Cool, thanks
Y did you under size the box slightly? JBL reccomends 2.5, I figure to save on size but I've always wondered because my trunk sucks and if I could down size alil I could fit different subs I currently own
There is no diffinite box size. You can rather calculate to what car space available using apps and programs.
Thanks for sharing the video and the information! Very useful (and entertaining with your lovely dogs running around). Excuse me if you already answered this question but what is the radius of the bended part of the port at the front and did you change the total port length? I have read that when using a (large) flange the outer part of the "mouth" shouldn't be used for determining the total length of the port. Ps. Could you also share the dimensions of the box? Tia.!
Many thanks for such inspiring feedback. Curve radius is 12" (outside dimension). There are exactly 12 kerf cuts with 10mm interval. Flanges and such don't really matter to me when calculating. All I do is to measure inner dimensions minus all the displacements when calculating boxes into BassBox Pro and WinISD.
There is a link to the TinkerCad schematics of this box project. 😄
@@chrclmnky Thanks for the reply! Are you sure the radius of the port curve is 12"(inch)? 😄
@@edwinburggraaf8224 Maybe half only. I am really not sure. Like I said, it really doesn't matter to me.
Badass bro, great looking Box!
I am a JBL Fanatic, I just got the Partybox 310 and have had their Endurance Sprint Bluetooth Headphones and am blown away by the Sound Quality that JBL Produces. How do you say that Sub sounds overall? Is it loud enough for you? I'm thinking of doing 2 of them in a Ground Shaker 30Hz Enclosure.... If not I'm getting the new Alpine Type X. Just curious on your honest opinion after having owned it and listened to it for a while now? Are you satisfied or would you say it's not quite loud enough, being it only Produces 500 Watts RMS VS The Kicker L7 & Alpine Type X that produce 800-1200 Watts RMS?...
Thanks for the feedback. I suggest to just get B2, DD, DB, or Sundown subs for any builds. They're a bit pricey but worth every money spent.
