Sorry, don't know anything about your sub, but I can tell you that good quality cables CAN make a difference. Note I said CAN, and not WILL. I had a powered sub hooked up via a cheapie cable, and had the power cord for the sub near it. The cheapie cable allowed 60 Hz AC line hum to be picked up through the cables, and the powered sub would emit a slight buzz. Switched to decent, not $60 MONSTER CABLE, but decent SHIELDED cables, no more buzz.
I would also like to throw in that the distance you plan to run the cables should also dictate what kind of quality you buy. Longer run = better cable needed, in my opinion.
