Carbon Fiber Subwoofer Box?


Recommended Posts

Anyone ever seen or heard of a subwooker box being built totally or partially out of carbon fiber? And I'm not talking about just a carbon fiber overlay or a fake vinyl wrap. I mean actually structural walls made of carbon fiber. I've got a 100x60" roll of the stuff and gallons and gallons of resin just sitting in my warehouse, so I was daydreaming of doing something stupid with it.

Yes, I know it takes a LOT of CF to build a speaker box. And MANY, MANY layers. I build motor plates out out of CF as a hobby and they are 1/4" thick, taking 28 layers and using roughly $300 worth of material, so a true CF speaker box could cost thousands in material alone. But wouldn't it be cool to have a 16 cubic foot speaker box that fits 2 18s and weighs in at under 30 pounds? Maybe I'll build one as an experiment for a 10" or 12" sub for my wife's Lexus first and see how things go?

Just thinking out loud here......

Anyone have any links, pics, or stories about such a thing, or am I just a blithering idiot?

i tried for a 12 testing and the box sounded horrible and by the way its a pain in the ass when trying to make a port and dealing with carbon fiber. Good luck tho.

When your at the top everyone is coming for you, friends, family, haters and even those who don't know you.. my advice.. KILL EM ALL

How thick did you go (layers), and did you use any filler at all to increase the thickness?

never heard of a box built with it but i think it would be pretty bad ass

.....if it worked and sounded ok, it would be truly, epicly, badass. I'm just not wanting to waste my time doing something that will never sound good, no matter how well built it is. Throwing away $4000 in CF and resin would suck.

CF will suffer from the same thing as all other materials and that is the box resonance that will occur with it, it is quite possible that it may be worse as the thickness won't be as thick as it should be. While it would be badass to have something made of CF it is not a practical or financial thing to do.

I agree. Box resonance as a result of low desity is probably the one obstacle that could not be overcome just because of the nature of the material and its low density. Afterall, that's why we make our boxes out of MDF and not plywood, superior density. Maybe I'll just make an amp rack out of CF or something else cool. Just brainstorming here, really.

just asking, but would a sealed enclosure have less problems with flex or resonance? I was just wondering because isn't a CF enclosure similar to a fiberglass enclosure in terms of resonance? I mean people make door/kick panels out of fiberglass too, couldn't you make CF door/kick panels that would perform the same?

this idea has Rear folding seat, flush mount CF box written all over it
