The points you make about form versus function are very very good. I had been on the high end audio merry-go-round for many years, and have spent way too much money in the hobby. I am really enjoying your videos from the standpoint of aesthetic design knowing full well the sonic compromises some of your designs might have. But really, who cares about compromises? You are creating great videos of awesome audio projects that are inexpensive, and within the reach of most people's skill set to build. It's fun to have expensive audio gear in your home that you worked your butt off to afford. But in many ways it's probably more rewarding to build your own speakers with your own hands without breaking the bank. Keep up the great work, Kirby!

good video. I bought one home theater dvd and it finally broke down, the speakers are ok though. could you make a video explaining how to disassamble it and make a sound bar? that would be nice!

This channel really makes me want to finally get going, Allways wanted to build speakers. What do you think about making a sealed 2way out of MDF and have some kind of reinforcement inside with the help of high density epoxy?

I like the mdf that comes with the 3mm solid vaneer on one side.

If I may I'd like to chime in with an observation about plywood. The greater the number of plies, the stiffer the board. I noticed that you had some nice 11 ply along with some thinner 3 and 5 ply boards. While the thickness of the wood does contribute to the overall stiffness of the board you can sometimes get away with using a thinner board with a greater number of plies to the same effect as using a thicker board of lower ply density. Example: 1/2" 11 ply would be at least as stiff as 3/4" 5 ply. This is if both are void free. 1/2" void free would be stiffer than 3/4" 5 ply with voids. At any rate, keep up the good work. I enjoy seeing what you come up with.

man, i really love this channel, you have made me wish i build speakers again, i haven't build speakers since highschool, that was 12 years ago :D

Very true. I built an experimental open baffle tower using an actual cardboard box from Home Depot and it sounded fantastic! Even the bass from the 15in woofer was thoroughly satisfying. No vibration issues whatsoever, for the sound, which was quite shocking to me. But because the cardboard was so soft it wouldn't hold the larger woofers for more than a week.

Great work Thanks

Im using 9 ply 15/32 baltic birch on a small car sub box for 2 Sundown SA6.5 SW. Drivers arent loaded yet, but this thing is pretty solid. I felt like I didnt need 3/4 because its 9 ply and small dimensions with lots of 45s and a port for support. Is the difference really that noticeable?

May I please ask you, what if I want to build tweeter and mid tone into an open baffle, what wood would you recommend there?

Old Video helps me in 2020 nice thanks 🙏

heyy Kirby I am very interested in a backpack speaker, is that a great idea and if it is how can I do it?

Hey Kirby! I was wondering if it was possible to mix the material used for the enclosure. I was thinking of using MDF for the entire enclosure beside the front, which I was planning to use hard maple. This way I could have a nice shinny black finish on the MDF and a nice stained for the front of the speaker. TIA

Well, this is actually a good video because were discussing the issue and it's a big one! MDF, Highdht, plywood,Corrian, and many more examples of speaker building material all have good and bad points. Panel resonance is actually the big problem. Increasing stiffness and creating stiffness is what needs to be achieved. It cannot be done just by increasing the mass of the panels although its a good place to start....sometimes. Damping or "pushing" resonance out of the problem area is the best solution. Developing a critical material and killing off resonance altogether, by reducing panel masses to a low/no level and preventing energy storage in the first place is the right way to approach this subject. There seems to be real interest in this area so i will be making some videos soon to explain the maths and how to do this cheaply and quickly.

Very informative man

If you go for solid wood, expansion and contraction due to variations in temperature and humidity should be considered. Especially if you plan to build larger cabinets for e.g. subwoofers.

Sound like an awesome project! Yes, that would great. The front and back of the speaker is called a front baffle and back baffle. It's important in designing your speaker to have a rigid front baffle to handle the vibrations of the driver, plywood is great for that.

Voided can cause gaskets to leak if you don't fill the holes with glue. They don't tend to leak from top to bottom but through the board edges. Most stores only have the cheap stuff and the cheapest Baltic birch is usually about 60 quid for a half inch or even 3/8 4 * 8. Also cheap stuff splits more easily and becomes delaminate and is still 25 quid a 4 X 8 sheet of half inch

It depends on the thiele small parameters although as a general catch all case I would go about 1 cubic foot and 50 Hz port per speaker unless you are using subwoofer then you can go with a smaller sealed box or a 80/90 Hz port tune. With subs I would rather use 6.5" pa mid bass like a faital pro 6fe200 and separate tweeter

Yo Kirby. It's a good thing when you say: Build YOUR speakers the way YOU wanna do it...that's the best advice you can give! The second best advice, I haven't heard you say, but that's okay ( ;-) ) , is: Do NOT be afraid to make a mistake....wood is very forgiving, mistakes are most of the time, fixable! Keep up the tutorials man, it helps! Thanks :-)

your cool

7:16 You seem pretty disappointed in yourself haha, also, great vid

One quetion tho, you havent said anything about weight. If the weight is the problem for example portable blouetooh speaker, what is the best compromise between weight and quality. For example is it better to use 1cm MDF od 2cm solid light wood. Btw, great videos! Keep up the good work! ☺

I have been in the cabinet business for about 50 years. Solid wood is going to be a bit tricky for anyone without a well equipped shop. The panels wood need to be glued up panels to help with dimensional stability and warping. I did see a video recently about the resonance of various plywoods and MDF(actually wood fibers glued under pressure, particle board is made of sawdust). I have used a lot of MDF over the years. I think it is easier to either spray paint or veneer it than cope with the raw edges of plywood. Particleboard, while quite dead is not really a good product to use unless you have access to industrial board not readily available to an individual. MDF does wear your tools faster than wood or plywood due to the adhesive resins.

Mdf is cheap which is good but i had both a cupboard and bed made of mdf And it was infested with wood larves and termites It was horrible So i am kinda skeptical to use it What material can i use that bugs won't get in again ?

Funny thing, look at how Harbeth design their speakers, they are build to flex, using thin materials, just an interesting observation.. Thanks for all the good videos :)

You can finish MDF to look like real wood with grain with EASY techniques with a brush and like this

There are several types of MDF. 1. Home store quality 2. Industrial MDF The second type comes in sheets 97 x 49 inches, Is much heavier and denser. Go with Industrial MDF. Cons of MDF - Water absorption - don't use it near water.

Hey I'm actually making a blowthrough box in my 86 f-150 for 2 18's right now. Have you had experience with waterproofing an mdf box? You think rustoleum and a clear coat is enough?

I'd say MDF isn't the easiest material to work with, all screw holes have to be pre-drilled or it'll split and it creates a ridiculous amount of dust when you cut it, it has good acoustic properties though. One material you didn't mention that I like and that is quite common is particle board, it's not quite as "dead" as MDF, but it's really cheap and quite strong and relatively easy to work with. As one sound guru on a car stereo forum once said "it doesn't matter which material you use, as long as the box is rigid and strong it'll sound good".

Sir i want to make 5.1 home theater with good base.please can u tell me all spare part which are required like woofer ,speakers,tweeters,board.i want to use like home theater.directly connect to plug board in home.if u tell me i will go to electrician to connect them.please tell me sir.please sir

I some times prefer to use particle board. There's some upsides and downsides, but otherwise its a really good material to use. Here are the downsides first: Downsides: -Heavy -Not very easy to work with as its a really hard material. I broke a hole saw bit i was using cause the board was so hard. -Not easy to finish cause the edges aren't like the top and doesn't really have any grain. -Its not as forgiving as some other stuff, because If you put a screw too close to an edge it'll crack the edge of the board -Can be costly Now for the upsides: Upsides: -It is a very strong material -It has good sound reverb even if its thin -It is really sturdy so if your making a speaker thats gonna possibly get bounced around a lot, its good for that. -It can be made water proof if u seal it with wax or a clear coat

Hi Kirby, Nice video again & 70k subscriptions, this is going fast! In this latest video you said, if you have any question, please ask them. Well, here I go: Its probably basic knowledge in speaker building but why do YOU use filters in your builds when you use a full-range driver? you don't have to be to detailed when you answer, a nice link to some documents will be fine. (I found "extremely" different results when trying to find the best way to build them) Thanks in advances a& keep up the good work mate :)

@KirbyMeetsAudio

Thanks so much for watching! You'll find opinions on the extreme end of any conversation around speaker building. Everyone has the "correct" way of doing it. Although there are some solid ways of building speakers, most rules are just opinions. Everyone has has to use their own ears to hear the audio, so testing and seeing what works best for you is the way to go. As for your question, you don't technically need to filter a full range driver and I've made lots of speakers that only had filters on the tweeter. BUT if you don't filter the upper frequencies of a full range woofer and you add a tweeter, you're essentially doubling the volume of the high frequencies. This can be fine if thats the sound thats pleasing to you, but if you want a nice flat frequency response, you should probably add a filter the the woofer. Thanks again!

Sir plz tell me speaker cabinet joint glue??

What brand of shirt is that? Also, great stuff!!!

You didn't mention veneered plywood with pre applied oak , cherry , or other .Is this type of plywood not used for speakers ? Also if you double up two sheets of 3/4" to 1 1/2" ply wouldn't it be more ridged then 3/4" of MDF for about the same Weight ? Where do you guys buy your speakers from ?

...and then there are veneers. Good way to make real wooden and even look over cheap and not so good looking base material (e.g. spruce plywood used in construction sites). Not all of the veneers are expensive, but it might be bit difficult to find suppliers that are glad to serve also customers with small quantity needs. But luckily there are those also! Okay, veneering does need more work (defining assembly sequence and which parts are veneered before drilling/milling of holes and assembly of enclosure and which not, gluing with even pressure and trimming) and tools (especially clamps), but once you get used to it, it is not that difficult to work with.

So, that's why my cardboard prototype sounds like crap. :) Going to use baltic birch 23/32"

@frankthetankricard

7 жыл бұрын

Drivers, speaker wires, crossovers if you need any, speaker terminals if you don't want a permanently attached cable, wood glue and the cabinet material. For tools you can get away with a drill and a jigsaw but this is by far the hardest to work with because you want precise straight cuts and you can't match circular saws in that regard. I've used a jigsaw for a large standing cabinet before and that build involved an ungodly amount of sanding to align the sides. Now I have a handheld circular saw and only use the jigsaw for the round speaker cutouts which don't have to be quite as precise. A router is the best option for this part but totally unnecessary if you don't build cabinets often. Other than that you just need something to hold the pieces together while glue sets, clamps and brad nails or wood screws are commonly used.

That "Mursi tribe girl" earlobe deal is a good look for you dude...

Probably gonna get at home depot. "1 in. x 12 in. x 8 ft. Premium Kiln-Dried Square Edge Whitewood Common Board" 1 inch is thick enough and its a solid piece, Whitewood is pretty hard, yeah you can spend time finding a better wood at a specialty wood shop if you'd like.

A concrete box??.

Lazy man's speaker building... take a pair of already finished speakers (that have nice "boxes"), and just upgrade the drivers (and maybe the crossover too). Optionally you can restain them or just leave them as is. Remember the simpler something is, the quicker it can usually be done. Also, by upgrading, I don't always mean replacing. Doping (coating) a paper woofer with silicone sealer on the front side only may make it sound better to your ears. If there is room in a 3 way speaker box, perhaps add a passive radiator on the rear. These are fun tweaks and they don't cost much and you wont need any carpentry skills or make any sawdust.
