I'm ordering an SVS PB1-1SD. I know placement has an effect on sound and I have identified my top 3 locations to place the unit. Choices #1 & 2 can be reached with a 15' cable (or less) . Choice 3 requires 25'. Should I get a 25' cable and just coil it if I don't use location #3 or should I try to minimize cable length and order the 15' and hope my first 2 locations work out? I plan to use a Canare LV-77 cable from Bluejeans.
