I am looking to connect some flat panel speakers directly to my amp. These speakers are meant to go via a sub which cuts out everything below 200Hz. As I'm not using the sub for the LFE (I have a Rel for this) and the speakers are just used for the rear surrounds I would like to remove the sub from the room. The only problem is that I can't use the amp's crossover at 200Hz as I have this set at 80Hz for the fronts. So, I think I need to put a capacitor in series, however am not quite sure. Does anyone know whether it is just a single capacitor and if so what value?
