This has probably been asked before but, is there any real difference between using a regular high grade phono cable over a propper high grade subwoofer cable? The reason I ask is coz im using a phono cable just now. It's a good cable and Im using it instead of the bundle cable that came with the woofer. It has made a huge difference in terms of sound over the bundle cable. I wonder if I would get an even bigger increase in performace if I used a propper subwoofer cable, or if its not really worth bothering over? Any advice apreaciated!
