Awhile back i seen some one who built a box for 2 12's and they put sound deadener inside the box. would this have any benifit? or would it actually hurt performance of the subs.

I think people line cotton on the inside of boxes to make sure the sound wave doesnt bounce around to much inside of the box. I would think that's teh idea behind the sound deadener inside the box too. If thats what you want to do I would jsut use cotton though..save money and i dont think there is alot of performance benifit anyway.97 RS,3.73 LSD,Flowmaster,Shift Kit,Edge TC,HP Tuners,EWP,SLP CAI,160*,Touchscreen monitor,& Alpine Stereo(155.2dB)15.27 N/A 1.9X 60\'s and a magic switch.Comment

Umm, pretty sure this idea is a hoax. I have heard that polyfill breaks up "standing waves"....sure. But sound deadening is used to add weight to panels to reduce outside induced noises. I don't see a properly built box gaining anything from this.Comment

Well I rarely pull rank, but as a physicist that works in the field of acoustic wave propagation, let me assure that that explanation is complete and utter bull shìt.Originally posted by 96firebird311:

We build boxes with manufactured woods precisely because the materials are less compliant. Adding a compliant material inside the box is silliness.╓<br />║ Matt M<br />║ <a href=\"http://home.austin.rr.com/morrism/3800/sunset_logo2.jpg\" target=\"_blank\">Down with the Sixxness</a> <br />║ Polo Green 1995 3.8 Camaro<br />║ intake, cat, catback, shocks, 3.42\'s, and 12\'s in the trunk<br />╙Comment
