I agree with Stanwal. I am a cable designer and manufacturer. While designing just for bass is less demanding, you end up finding the same cable design that is best for full range sound is the best for just bass.
Special Sub-Woofer IC's
I currently have my Sunfire HRS Subwoofer connected to my pre-amp outputs with full range cables and it sounds pretty good. The question is, are supposed "Subwoofer" cables preferable? Do they really make a difference, I would think that a full range cable would be better, sending the full spectrum to the sub and then letting the sub decide what to reproduce, or am I incorrect? Thanks!
