Weirdly, the point nobody ever seems to make regards the fact that recorded music has vastly disperate bass levels. I stuck a "chicken head" knob (left over from a guitar amp) on the gain pot on the back of my REL sub so I can (easily) adjust the level by feel without moving the sub away from the wall..this adjustment is to make things sound better...sort of the point of this hobby. I don't have tone controls on my preamp (because they're simply not cool) and absolutely do not need them...ever...and the crossover point stays the same...but the REL gain knob is needed often for small adjustment, otherwise I'd be stuck with anemic bass on old LPs or my walls would crumble when a large bass level kicks in on any number of recordings.
