I recently got some RTi 28's and have it paired with a PSW 450 sub. It sounds good but sometimes the bass seems to be a fraction of a second behind the RTi's. My RTi's speaker cable is a 14 awg 15' long pair. The sub cable is AR 25' long. Is it possible that the difference in length could cause a slight time lag? I was thinking about getting a shorter sub cable if it would possibly help. Any thoughts or is this just another crazy dead end.
