This is a brand new 30ft long and unused REL Speakon cable which came along with a REL subwoofer from the manufacturer. If you need it, get it, don't bother buying some $300 custom cable, all this cable has to do is carry a low bass signal.
I also have
1. Two 1.0 meter pairs of Monster THX RCA interconnects (9/10 rating) - $20 each
2. Two 0.5 meter pairs of Emotiva XRCA interconnects (9/10 rating) - $10 each
Flat rate shipping of $10 to be paid by buyer
