c70

Newbie here, but long time audio enthusiast. I have a C-70 I bought when stationed in europe in the 80s ( I loaded up on lots of low priced high fi !! ) and its one of my favs. In the 90s it developed a channel issue that a local worthless repair shop fixed with a install of a new balance pot (...

Is it a good plan to use the C70's "Invert" output to feed a powered subwoofer? The sub (Velodyne F-series) does feature a built-in crossover.
