Wires aren't directional. It's a bunch of hooey.

Niv, your gymnastic efforts in doing that wiring made for thrilling reading, but why are you using speaker wires instead of simply a coaxial cable from the receiver to the sub amp?

John, if he has an In cabinet sub.. The amp is a separate, the driver and its enclosure is just like a "regular" speaker.. The RCA to the amp, then wire to speaker just like any other speaker..

Amie, it might be worth pointing out that the Subwoofer drivers are Dual voice coil drivers, and require a pair of cables to power both voice coils (especially the inwall subs such as niveka has, maybe this could be brought up at the time of purchase if ordered over the phone)... In the Version 1 of the EP-600's there was only 1 "amp", so Niveka would not have had a problem. But, the new design has an amp for each voice coil. I don't think this is something most people would assume, I think most would assume that there would be one amp channel powering both voice coils in parallel.

Yes, if that's what was actually done. Since only speaker wire and not coax was mentioned, I took this to mean that the entire wiring run was done with speaker wire.

When i read your reply, i had to think about your question for a minute. Then re-read the referenced post before deciphering what is going on, i think....

John,

The in-cabinet EP500 has an external amp, for me, it sits in the same area as the receiver. A very short run of coax goes from the receiver to the amp. The output from the amp is normal +/- speaker wire.
