Sir would like to purchase a box design for my truck. How could we get going?

[@K-Effect]

I bought 20 of those GRS 12s about four years ago, at the time I think I paid $13 a speaker. I was going to build a cheap subwoofer to annoy my neighbor across the street when his dogs bark. The dogs don’t bark anymore so I didn’t build it. I’m now thinking about building a infinite baffle subwoofer with all 20 of them in the basement and have the port’s fire up into each corner of the living room

Thanks!

[@DodgyBrothersEngineering]

I'm giving you a thumbs up simply because you didn't try and BS us that you built it for $23. Like you I have a shed full of tools (not that I can get to many of them) but even if we have material left over from a previous project, it still cost us money at one point, and I like that you didn't pretend it didn't. All going well I hope soon to start on "the internets most expensive DIY sub build" (maybe not the most expensive, but we are talking a lot of thousands).

[@DIYAudioGuy]

I would like to see that!

[@DodgyBrothersEngineering]

@@DIYAudioGuy so would I. I bought the LMS Ultra 5400 driver and 18" VMP passive radiators before TC Sounds went out of business. I have been sitting on them for nearly a decade now. I'm in the process of refining a six sided cabinet for it. I figure there will be about 5 - 6 sheets of 16mm MDF in it. There are a few experimental things I would like to try, like dampening paste between layers. Also tossing up if I want to use dissimilar materials (both MDF and Ply).

[@TheTherumble32]

I paired two of these ten inch versions with 15” passive radiators individually and they sound great for the price

[@anthonymills2321]

helped me so much. no other videos like this ON A BUDGET. thank you.

[@gibbytravis]

@5:35 standing waves are not normally a problem with subwoofers. Usually the enclosure is much smaller than a half of a wavelength at the cutoff frequency, so standing waves cannot occur.

[@leehess6335]

When I was younger and 46 now but the late 90s early 2000 everybody had big stereo system in their cars custom done. Fax and everybody didn’t have cars in the head and my stereo system and they’ll everything comes with it but my stereo pretty much depending on what type of car you have but even an average car the radio sounds way better than anything back in the day

Sweet build! Four of those subs on a 400 watt rms amp would be a fun setup!

If I were going to do that I would put them in a bandpass enclosure.

[@bradlwykfulbright]

I bought the 8 ohm version, 2 of them. One is in a sealed box for my home theater, it shakes my entire wood floors, I feel earthquakes in movies and only pouring with about 200 watts. I'm going to buy 4 of the 4 ohm for my truck blowthrough budget demo build! These subs rock!!!

[@DIYAudioGuy]

I like cheap subs and I cannot lie.

[@bradlwykfulbright]

@@DIYAudioGuy that sealed enclosure i built is 2 cubic ft, half filled poly just dropped in not stuffed and one layer of the yellow sound dampening on one inner wall. It plays beautifully flat, hits all of the notes with crossover set at 50. The cabinet it is in is an old stereo console from the 70's. Gutted with 2 sub enclosures now built in. Only using the sealed side, dont like the way the ported side turned out, its 2.5 cuft.. i took that one out until I re build for another sealed. I dont like how ported boxes sound in my house, it's ALL wood floors with basement. Doesnt take much power to shake pictures. Downfiring subs, I raised the whole console by adding just 3 inches allaround and left the fancy cut open on front, making it a 4th order. Turned up, I can feel it in my chest, like I'm at a concert.

[@djijspeakerguy4628]

This GRS looks very much like the OEM driver from my Klipsch ksw-12 home theater subwoofer. I replaced it with a Dayton classic series 12, which has a much, much larger magnet and stiffer feeling suspension. I was skeptical at first about low end extension, (don’t care about volume,) but it rattles a door in the room at normal listening volume due to being punchy and quick, and yes, it goes low too.

[@DIYAudioGuy]

I've been using one of those classic 12s for my DIY home theater sub for about 6 years now.

[@djijspeakerguy4628]

Yeah I think they are possibly the best deal in subwoofers. Instead of getting a new sub, just grab a cheap one at the thrift store and stick one of those Daytons in it! The Ksw-12 came from a neighbor, for free and was not powering on. I replaced a blown fuse and a faulty fuse holder, and it has worked ever since. Perfect sub for the Dayton driver!

I'm definitely going to be use this guide to help me be successful in the stability of the Bass box ☑️

[@FSXgta]

I like to cut the baffle before I mount it. Easier to sand bigger if my cut is slightly too small

[@DIYAudioGuy]

That's definitely the way to go.

[@trentbriand]

I cut the hole in the baffle before even gluing both layers together for a clean flush mount. Also adding t nuts and screws rather than wood screws. Way more clamping force and no worries about stripping out the holes. Cheap insurance.

[@DIYAudioGuy]

That is typically how I do the baffle. kzbin.info/www/bejne/bKnSoHyKepVggZo I am not a big fan of t-nuts, in my experience they are not worth the trouble and they are not as good as threaded inserts.

[@brianwatson3705]

The box itself IS a budget build. The tools , not so much. Title of the video is pretty accurate 👌

[@DIYAudioGuy]

[@naturalverities]

Budget tip: if you buy quality tools used you can use them for as long as you like and resell later at little or no loss. Blades and router bits are another story, but carbide is a good investment in edge life.

[@DIYAudioGuy]

Absolutely! Just have to make sure all the parts are there when you buy them!

[@artv4nd3l4y]

​@@DIYAudioGuy You also have to make sure you use them enough to warrant the cost. i.e. sure a 14 inch circular saw is nice, but does anyone really need to cut down an 8x8 at a 45 miter in one pass? I would not cheap out on some tools though like a router, everyone always seems to have a really underpowered one and they're not that expensive. The router tables with easily adjustable lifts are the expensive part, I find the plunge base to be awesome. I built a router table and have hardly used it.

[@crzjohn4275]

30 yrs in car audio/customz here.. tips - just before u painted it.. use wood glue on moist rag.. wipe it around the outside of box over that grain and it fills/vanishes.. sometimes it takes a few rounds of drying but it'll smooth, then spray it with filler primer (automotive) and sand back, repeat.. then use epoxy based paint for furniture, clear it with polycrylic and detail it.. it'll look like a piano.. you can also wrap it with vinyl and a torch thats low budg

[@DIYAudioGuy]

Thanks for the tips! I ended up repainting and uses some automotive primer, that made a big difference.

[@kramnull8962]

Don't you need a finish for Vinyl? Besides the wood surface?

[@DIYAudioGuy]

@@kramnull8962 as far as I'm aware you can just glue a vinyl on, the trick is using the proper adhesive, and making sure the surface is smooth because any bumps will show up in the vinyl.

[@crzjohn4275]

@@kramnull8962 best adhesion possible for iron-on vinyl products like faux wood grains n such OR real grain laminate with wood glue - would be on a KILZ sealed surface lightly scuffed with like a 3M 7447 pad.. Automotive grade or commercial grade decorative vinyl needs a smooth smooth flat sealed surface to adhere longterm and not show flaws thru it. use something like a 3M Ultra Fine 7448 after stepping down from higher grits and use a heat gun on low to lock the vinyl in. (94-110 degrees only) auto vinyl i highly recommend vvivid out of canada its perfect every time for me. hope that helps

[@crzjohn4275]

i think you might like gelcoat from the boat world if you do alot of these, learning spray techniques is fairly easy (YT).. or even use epoxy/mica countertop/surfboard style art techniques on inserts or accent panels is also a way to take your stuff in all new directions on the cheap.. LED and incandescent panel lighting is dirty cheap these days and can be a huge pop for like $8 off web.. and if you see a car, exotic whatever with a paint job u love.. look up the paint code, hit up an online company that mixes bodywork paint in cans and have at it.. like $34 a can.. theres tons of cheap tricks that yield incredible boutique design results. great vids bruh :-) keep craft skills alive!

[@peterrabbitwarren]

Great video, thought I'd ask this question before the end otherwise I'd forget. When you round over the corners how do you know you won't hit a brad nail and damage your router bit?

[@DIYAudioGuy]

I have hit a few. But I have not had any noticeable damage.

[@tan.91]

haha i done a "budget buid" not long ago only using an old record player speaker box, a jisaw, some carpet and some pvc pipe and to my complete surprise the sub that i put in it sounded really good (it wasnt a budget sub but it did sound good in a budget box)😂

You could probably do a flared ported setup and if you don't play it too hard you could tune it well into the 20hz range.

If you don't have much money and you are okay with spending a bit more time you can build very nice speakers with Max 50bucks of tools.

@@DIYAudioGuy that’s true. I guess I gotta practice before I do that all I have is a jigsaw and I don’t have a very steady hand. So best to not screw it up lol. Speaking of. Do you have any tips to make sure I don’t cut the hole too big/too small. Or uneven.

[@DIYAudioGuy]

@@the_allamerican7057 two screws and a piece of plywood Will get you a very good circle. A sharp blade on the jigsaw, and set it so that you can cut curves. Then all you need is a steady hand, which just comes with practice. It would not hurt at all to grab a bunch of scrap material and just practice cutting circles until you think you've got it. The first subwoofer cut out I ever made was absolutely terrible. The good news is that subwoofers usually have a pretty big mounting flange, so there's a little bit of room for error.

These subs are now $35. But still worth their cost. I've used them in many projects, they play well up to 800hz so can be used as a woofer in 3-way setups but still hit the low end like a sub. They should be ported at 30-40hz in a 2ft^3 or more enclosure to get that chest thumping effect with just 60-100 watts. Sealed enclosure is no good with these.

[@naturalverities]

I have my eye on these drivers to replace a really nice B&C 18" cast frame pro cinema sub that is disappointing in low extension. I can mount the GRS (4 of them! ;-> ) in the interior wall of my barn loft listening space in a true infinite baffle configuration as their Qts is about 1.0 and the room behind is quite voluminous and only used for storage. This should give me strong bass down to below 30hz, plenty low enough for music. And their lackluster sensitivity should be greatly improved by acoustical coupling from cluster-mounting them, giving me a close equivalent to a 24" driver. I should be able to sell the B&C used and be money ahead, or I can repurpose it for mobile DJ use where it performs really well.

[@DIYAudioGuy]

These are great speakers for the price., Just keep in mind they are inexpensive for a reason.

[@naturalverities]

@@DIYAudioGuy Sure, I get that. Other than the modest f3 in the small sealed enclosure, did you hear other audible evidence of their budget quality that would make you hesitate? I'm kinda thinking vast piston area covers a multitude of sins at moderate spl and low X. But maybe clustering results in underdamping of already high Qts drivers? Cheers!

I made a VERY VERY CHEAP bass box. I used very insanely thick cardboard 5bucks and a sketchy 6 inch woofer 10bucks and a screwdriver 3bucks. Sound is decent unless you put 30 - 60hz it starts shaking and dances. And the box nearly broke 😅 (I'm still 10 that's why😅)

[@dlfrestoration]

I always cut the hole when the box is done as i try to always design the box so the drive overlaps the sides so it's more ridgid

[@DIYAudioGuy]

That's clever.

[@dlfrestoration]

@@DIYAudioGuy you show try build a tline with extremely braced box with a cheap drive and you will be amazed at the sound

[@waynepollard6879]

The holes for the woofer aren't symmetrical , which drive me crazy - took out a big chunk of wood on the front ?

[@DIYAudioGuy]

Yep, This material was MDF that was laminated with birch plywood. It's prone to chipping out.

[@billy3650]

What amp were you pushing it with ?

I was using an old school Kenwood 2 channel that I picked up at a yard sale for $15.

[@ajmann07]

Young Mann Anthony here with that question ? Speaker build is 2-2ohm 5-1/4 coaxial & 2-2ohm 6.5 Kicker cvt subs will give you all the specs in a email if needed. What coils and or caps should I be using for a crossover ? Up to 135-150hz for the subs and like wise for the Mids. Speakers will be wired in series. (Like you a Budget build it's what I have in the shop a 2 channel Rockford amp) This is a Ice Chest build FYI.

[@DIYAudioGuy]

That depends on how complicated you want to get and how good you want it to sound. You probably don't need any crossover on the coaxial. But if you want to filter out some bass try this: parts-express.sjv.io/yR79L2 If the mids and highs are to loud then you can throw on a resistor to turn them down a bit: parts-express.sjv.io/x97Qbv A coil liked this would make a good low pass for the subs. parts-express.sjv.io/rn7ObR That will give you a 6db per octave crossover with a crossover point around 120 hz. No guarantee that it will sound good. But it will probably be fine for a budget build in an ice chest.

[@salaovdeen]

Hi, how can I buy speakers from u, if I want

[@DIYAudioGuy]

I don't currently sell speakers.

[@3RDERA]

I’m going to take a wild guess and say that table saw costs more than the sub and amp and wood combined for someone on a super budget build. Maybe you plan on talking about that??.. I’ll keep watching

[@DIYAudioGuy]

Exactly.

[@cekpi7]

It's amazing how lazy people these days are, my first box was made only using jigsaw and homemade jig for cutting straight lines... Most of the things he did was optional, but you can borrow tools from some shops if you want to do them anyway. If you are on budget, you don't need to use table saw or router. EDIT: Some shops can cut wood for you sou you just need to assemble whole box (and cut hole for subwoofer).

@@DTW-bx2vy Not really. Currently its $36.54 at home depot. I believe it used to be higher, but before covid it was more like $20 a sheet.

[@A6Legit]

@@DTW-bx2vy Yeah birch is $60 a sheet, probably twice what it used to cost. Everything's over priced. Use iron on edge banding and you wont have to worry about plywood imperfections. I hate when people use ply and dont cover up the core. Defeats the whole purpose of plywood.

[@travisgulley2652]

Would it be a huge mistake if you accidentally got a 12 inch guitar speaker from parts express instead of a 12 inch subwoofer and ended up making the mistake of putting a guitar speaker into a subwoofer enclosure.

[@DIYAudioGuy]

Yes. Most guitar speakers, even the ones used in bass cabinets, struggle to hit the lows. But, they are very efficient.

[@Live_Loud]

Why you build box with plywood instead of MDF?

[@DIYAudioGuy]

kzbin.info/www/bejne/oYK6hn5uhq94idE

[@LBCAndrew]

I would have used a rabbit bit to add a step where the speaker mounts so it sits into the cabinet. And FYI, you don't have to include the cost of the machine equipment used on the project. The table saw can be a circular saw which can be a handsaw. Every one of the power tools can be replaced with a hand tool that you can get for a couple bucks at Harbor Freight or a yard sale. Lastly, that box looks way too big for that sub.

[@hiliax]

Works with Bluetooth?

[@DIYAudioGuy]

Sure, just need a Bluetooth head unit.

[@HifiVega]

Your mistake was soldering on YT I been told you 😉🤣. Good job on the enclosure man it turned out nice

[@LBCAndrew]

Using a nail gun like that, wait till a nail does a turn, comes out the side and hits you in the hand. lol. Yes, i know from experience.

[@A6Legit]

You could accomplish this box build with just a circular saw and a jigsaw (and some clamps)

[@DIYAudioGuy]

For sure!

[@melvinrubio2278]

Well, if you have a home you should at least have some of those tools. So, saying budget build is okay.

[@DIYAudioGuy]

That is perfectly reasonable.

I do wood working I also build Sub Boxes for the C 7 Corvette.

[@MrKeithsplace]

Never, ever, and did I mention never, have your hand in the path of a brad nailer, nail gun, or power tool in general. Your very lucky that you haven’t had a bad day yet. Seen many a shoot outs, stick outs, or shoot through from one longer brad left in gun from switching sizes.

[@DIYAudioGuy]

You are right, I have been lucky and I have had a few near misses. So I have started being a lot more deliberate -- holding things together with clamps while I drive the brads, that kind of thing.

I like sealed subs, I also like to throw a car sub in the house, if it doesn't vibrate every, a couple car 12" or 15", or even 18" subs go nice behind your favorite seat in front of the screen, as long as you don't have stuff falling off the wall and shelves! Ha..

My guess before the vid end: You probably didn't plan your cuts well and didn't take advantage of having duplicate pieces, hence less cuts.
