ben_eat_pie Posted June 24, 2008 Share Posted June 24, 2008 i've been thinking of building a fairly funky shaped Glass Reinforced Fibre bass cab - havn't heard great things about the material... here's a few points i'd like comments on: - why not GRP? - Anyone know of a carbon fibre bass cab? - Any other composite materials that are used to minimize weight! thanks guys, ben Quote Link to comment Share on other sites More sharing options...
voxpop Posted June 24, 2008 Share Posted June 24, 2008 (edited) Im in the hi-fi industry and these guys build fantastic high end speakers in carbon fibre starting at over £2k, check them out at............ [url="http://www.wilson-benesch.com/"]http://www.wilson-benesch.com/[/url] The sound of carbon is very unique, its gives a sound free of the woody, box colouration that MOST speakers have. Should sound great as a bass cab. Don't know how easy it would be to build / mould the carbon fibre. Hope this helps.

bass_ferret Posted June 24, 2008 Share Posted June 24, 2008 Moulded PA cabs have been around for years. Quote Link to comment Share on other sites More sharing options...
Kiwi Posted June 24, 2008 Share Posted June 24, 2008 For a rectangular cabinet, i think you would still end up with the same problems of sympathetic vibration if standard thicknesses of 3-4mm were used in the production of graphite composite cabs. This issue has been dealt with in basses by filling the hollow core of the graphite neck with polyeurathane foam but I can't imagine that working with a speaker cabinet. Part of the design beauty of speakers like the Nautilus is that the conical shape helps dampen sympathetic vibrations. But the moldings are a total bastard to make. Hence the price.

Merton Posted June 25, 2008 Share Posted June 25, 2008 There's a thread on Talkbass where someone is building one at the mo: [url="http://www.talkbass.com/forum/showthread.php?t=432560"]HERE[/url] Quote Link to comment Share on other sites More sharing options...
Kiwi Posted June 25, 2008 Share Posted June 25, 2008 Let's not also forget that if the cabs are too light may not actually sit still on the floor when running at full tit. The cone excursions may very well end up making the cab vibrate all over the stage unless the cabs are tied down or anchored in some way.

ben_eat_pie Posted June 26, 2008 Author Share Posted June 26, 2008 lol, i had a situation like that, my amp was on the table; i cranked it up turned away, and next it was tilting relying on a poorly painted wall to stop a hefty fall..... table was fairly smooth though - my dumbass mistake! this is all great guys!

Costs of making up moulds etc. would be very inhibitive given the relativley small number of consumers, and the cost of alternatives.

Manufacturing costs are at least double that of plywood. Some forays into fiberglass and other composite constructions have been made, most have failed.
