Axiom Home Page Forums General Discussion Technical Questions Quality of subwoofer cables?

How much quality do I need in the RCA cable for my receiver to subwoofer (HK AVR-230 to HSU STF-2)? Can I get away with the cheapo $4 15-foot Radio Shack unshielded cable, or do I need to drop $25 on this?

I'm sure this has been discussed, but a brief trawl through the archives didn't find it. If you can send me a link to a past discussion, that would be great.

thanks,
Robert

Robert, the only question would in fact be shielding, since if electro magnetic interference wasn't present any old thing that looks like a piece of wire will work fine. Impedance or gauge of the wire isn't significant, since essentially zero power is carried, just signal. If the cable in question is in fact totally unshielded(even some of the very thin ones often have light shielding)it may not give you any trouble if you don't have many sources of EMI around and you keep it well away from power cords. A coaxial cable, which is by nature heavily shielded, is usually suggested for a sub cable to avoid interference problems. There's no reason that it should run $25; a 12 foot cable(if that's adequate)is available from sources such as Parts Express for $10-$12.

John's right. I use Dayton interconnects from Parts Express, and am very pleased with them. You mention a 15 ft. cable. If a 12 ft. cable will do, I think this would do the job just fine.
