John, go over to Madisound.com and take a look at the thread by Scott (like on 6-06), "Peerless sub XLS", very nice photo of this musical sub. in a cabinet. KT88 , lately i've been doing research in the DIY speaker projects. Madisound has members that will design and build, Rick Craig , Dave Ellis and Dennis Murphy. Rick has a 3 way design underway for me. As well check out the sites that Clueless mentions.
