Hey everybody, I have a project I would like a little help with. First off, the sub I am going to use in this build is a pioneer ts-w3002D4, here is a link to the manual for all the parameters. http://www.pioneerelectronics.com/PUSA/Unassigned+Content/TS-W3002D2+INSTRUCTION+MANUAL. Ok, next the amp I will be using is the Behringer ep4000, 950wrms @ 4ohms, both channels driven. I feel that this is a good match up and allows room for the addition of another sub later on if need be. My room is approx 12x12, with such a small space I don't have a lot of options for sub placement with the furniture arrangement. I am considering putting this sub behind the couch, but the couch only sits about a foot off the rear wall. Could someone post some ideas for an awesome behind-the-couch box and maybe some graphs? Oh, and the couch is 5ft wide and reclines, so by measuring the max depth/height would need to be 14" or so give or take an inch or two. Any help will be greatly appreciated.
