Captain Stupid Posted August 13, 2012 Report Share Posted August 13, 2012 (edited) 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?

Ninja_v1.0 Posted August 13, 2012 Report Share Posted August 13, 2012 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..

How thick did you go (layers), and did you use any filler at all to increase the thickness? 2006 Cadillac Escalade 2/3 drop on 28" wheels Two RE SX 18" subs RF T2500-1bdCP amp, 3531watts on birthsheet Custom carbon fiber sub box EVERYTHING else is stock, for now 149.4 @ 37hz, Termlab, dash, open window on two AQ3 18s all stock electrical, wired to .25 ohm on a RF T2500 148.8 @ 36hz, Termlab, dash, open window on one AQ3 18 all stock electrical, wired to .5 ohm on a RF T2500 147.8 @ 38hz, Termlab, legal, sealed on two RE SX 18s 146.4 @ 36hz, Termlab, legal, sealed on one RE SX 18 Link to my hack-built, stupid, carbon fiber wasting project.... http://www.stevemeadedesigns.com/board/topic/149946-carbon-fiber-box-update-1494db-37hz-on-tl/ http://gifsoup.com/NDM3MTc1MQ Link to comment Share on other sites More sharing options...
Captain Stupid Posted August 13, 2012 Author Report Share Posted August 13, 2012 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. 2006 Cadillac Escalade 2/3 drop on 28" wheels Two RE SX 18" subs RF T2500-1bdCP amp, 3531watts on birthsheet Custom carbon fiber sub box EVERYTHING else is stock, for now 149.4 @ 37hz, Termlab, dash, open window on two AQ3 18s all stock electrical, wired to .25 ohm on a RF T2500 148.8 @ 36hz, Termlab, dash, open window on one AQ3 18 all stock electrical, wired to .5 ohm on a RF T2500 147.8 @ 38hz, Termlab, legal, sealed on two RE SX 18s 146.4 @ 36hz, Termlab, legal, sealed on one RE SX 18 Link to my hack-built, stupid, carbon fiber wasting project.... http://www.stevemeadedesigns.com/board/topic/149946-carbon-fiber-box-update-1494db-37hz-on-tl/ http://gifsoup.com/NDM3MTc1MQ Link to comment Share on other sites More sharing options...
Skullz Posted August 13, 2012 Report Share Posted August 13, 2012 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. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...

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.

stroupe79 Posted August 13, 2012 Report Share Posted August 13, 2012 (edited) 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 Edited August 13, 2012 by stroupe79 http://www.stevemead...cherokee-build/ 2005 Jeep Grand Cherokee Alpine CDE-hd148bt Alpine PKG-RSE2 PRV Audio (4) 6MB200 front/rear doors PRV Audio (4) TW350Ti dash/rear doors Kicker KX350.4 Obsidian Audio (1) 18 D4 v2 revamp (2) Stereo Integrity HT 18d2DC Audio 1.2k5.25ft^3 tuned @34hz revamp Infinite Baffle Cpillar AudioTechnix 60mil deadenerKnuKonceptz & SkyHigh wire (complete setup) Link to comment Share on other sites More sharing options...
