Forget about plastic. We have subs made of plastic here in Germany and they don't get that much output, because much of the energy is wasted' in inflating/deflating the plastic housing. No joke, it's true...

Actually, the thought was of a composite using plastic core material and fibre glass skins.

Hoo Timber, I have been building boxes using a paper honeycomb material 3/4" thick and covering that with 1/8 balticbirch.Very labour intensive but my labhorns only weigh 100 lbs. Cheers

Where do you get this material from Jerry? Sounds just like what I am after! How much is a sheet?

Seems this box had been " designed " around carbonfibre? It says it`s " lightweight " for a double 15" ....still 80 kilos tho` which is as much as most ply boxes ? There`s so much " teknowaffle " as well to confuse people!! http://www.qscaudio.com/products/speakers/isis/215pcm/215pcm .htm .p.

Yeah, but that 80 kilos includes a PL230 and a PL236 plus processors so it is a significant weight loss

Yoo Guys I make this stuff myself,that is why it is labour intensive.However,a sheet of 48"by96"by1"only weighs about 13 lbs and cost me in material $30.00.I have worked with all kinds of carbonfibre,but this is not really a process that lends itself to the diy person.I can tell you how it is done and send you guys some pictures of the process,as long as you are not in a hurry,as my time is very limited. Cheers Jerry |
