I have read much discussion on speaker wires and how they do (or do not) make any difference in sound but I could not find any info. on whether there would be any difference in sub cables. It seems to me that it would not matter since you are taking a low level signal of the lower frequency and then amplifying the signal in the sub. What is your opinion/experience with sub. cables? Would a $2.50 cable with RCA jacks on either end work as good as a $35.00 Monster sub cable?
