good subwoofer interconnects

First, most subs belong near the inside edge of the main speaker, though some distance back. One has to experiment.

This reduces the length of cable considerably, and thus resolves a lot of signal loss issues.

Since your sub is not powered, you get get a separate amp and run a long interconnect instead, or if you move the sub as per my suggestion, then a short one

So far this is the best I can find for my 2Wq's.http://www.needledoctor.com/Brand-Stores/Audioquest-Subwoofer- I like that it has some silver(sub-3)

Well the link didn't work, look up Audioquest Sub-3 subwoofer cable

The Zu Disco is fabulous in conjunction with my Zu Mini Method subs.

I have used the Blue Jeans Cable LC-1 sub interconnect for years with great success. This is a 30 foot run, no hum, no interference. It is at least cheap to try, with a no question return policy. If you don't like it, return it for a full refund.
