I bought a Behringer Feedback Destroyer recently but am not 100% sure if I'm doing the right things with it. I'm using a Pioneer receiver and a Velodyne CHT-15. I'm using the receiver's crossover, set to 80Hz. Here are my 'before and after' curves: As you can see, there's a wide peak around 32Hz which I've tamed by setting up a filter with a bandwidth of 10/60 and gain of -12. Is that the correct thing to do? Should I be applying other filters or is the curve flat enough? Any advice would be much appreciated.
