[QUOTE="jlaine, post: 35211, member: 542392"] No, you copied it correctly, just that his logic is flawed. You can't exactly disperse and intermix a wave that is 30 feet long inside a 1 foot deep box.. The research has been done, for the most part he has been proven completely wrong as far as subwoofers are concerned. Midrange? Sure, but subwoofers, he cannot gain any ground in terms of standing waves. Extracted from Richard Clark and some of his thoughts: I agree with him on this matter, and I do stuff midrange boxes, but I do not stuff subwoofer enclosures, I build them to the right size. I think it will aid you some in terms of box size for a woofer, but will not remedy anything involving a standing wave, as the wave doesn't have the space to interact with anything. And we do have some factual, documented figures about adding polyfill, done by Tom Nousaine, which can be read here: [URL="http://integra.cyberglobe.net/caraudio/resources/fiberfill/"]http://integra.cyberglobe.net/caraudio/resources/fiberfill/[/URL] [/QUOTE]
