I bought an RLS-15 (sorry not an RLP-15) a few years ago with a Behringer EP-2500 with the best intentions, to build an IB manifold in my livingroom ceiling. It turns out I am not a good carpenter and chickened out on cutting a manifold opening in my ceiling, so my IB dreams never came true. I just can't seem to make anything pretty out of plywood and MDF. I've listed the amp and speaker on ebay and hope that the RLP-15 will find a deserving home with someone who really understands this driver's capabilities. I ended up just putting a Axiom 12" subwoofer cube in the livingroom. I was sad to hear that Soundsplinter is closing and wish the owners best of luck in their next endeavor.
