Just a curiosity question. I never have. And I dont mean to do it with the finish look that we know of CF...but using a structural CF that has white thread woven into it. My friend works for a yacht building company, and the trash there is always overflowing with scraps of CF...so he gave me a TON to work with...and I have since patch up a hole in my rear bumper (regular glass) with the CF, and what a difference. It is really nite and day between the regular glass and the CF as far as rigidity goes.
Just a thought!

It would probably work pretty well...it is definitely strong enough. Since you have the materials...i say go for it.

Actually, CF seems like it would be LESS ideal than fiberglass for boxes (especially in flat surfaces). Fiberglass is actually more rigid than carbon fiber. Carbon has a inherently more flex than fiberglass. For car audio applications, I'd say carbon fiber is more of just an asthetic item.

this is not true F1 uses CF on transmissions and body panels, last time I checked you didn't want any flex on either part. as for a box CF mat will be outrageously expensive, just use MDF and FG

CF will make for a very strong panel. I would say it would be a great waste of money though. If you want the look, make the thing outa fiberglass, then just lay a layer or two of CF over it.

Carbon is significantly stronger than fiberglass PER UNIT WEIGHT. F1 teams could build the same part out of fiberglass, but it would be significantly heavier.

Carbon fiber composite does not work very well for a speaker box. It is plenty strong and stiff but it it doesn't have very much internal damping which will result in sound passing through the box and messing up the sound. It would be like making a box out of sheet metal, which is also strong and stiff; the box would have a ringing sound. I have heard of people trying an all carbon fiber box and even with dynamat lining the inside for damping, the sound was still not that good. I have not heard of it being used for a speaker box but kevlar has an even higher internal damping than fiberglass, and I think that it would work even better for the same box thickness, and could also be lighter than fiberglass.

maybe I'll give kevlar a try....I get tons of kevlar and CF for free, so I'm not paying for it. Its amazing what a yacht building company throws away!!

I'd listen to this guy...
But even kevlar wouldn't make a great choice in building a speaker enclosure...it'd ring like a bell.
