tqwt - cork lining

ark · 3rd February 2013, 02:40 PM

I'm building a set of these TQWT cabinets for the 12" full range driver out of two layers of 3/4" baltic. I've got everything cut and about ready to close them up now so I need to figure out if i need to anything inside first.

I have a roll of thin cork material and thinking about gluing it to either the lower section at the mouth (so i don't need to veneer it) or to just the side panels (inside) or just to the inside line, or all of the inside.

Any suggestions?

This is similar design to post 14 here TL-box for BG20 Visaton
It sounds like area around the fold and around driver are more important than mouth. You need stuffing in the closed end for sure.

If it's for aesthetic reasons, why not. I quite like cork. It won't have much damping effect; not on the pipe resonances at any rate, although it may produce some slight damping of panel resonances / lower them in frequency. Whether this would be audible, or if it is, a good thing, is another matter.
