That is exactly what I mean. I have an option on my current reciever that is labeled "disco" where the center channel is disabled(it also adds some reverb, but I turn that off). What you get is a very wide sound field from the sides with the rear speakers just being sent stereo signal. Its just a preference of mine for listening to music. Unfortunitly several of the recievers I have looked at have not had a way to do this(or I just didn't see it right off without having to individually set each speaker level). Also, I know the sub is powered, but will a change of reciever change the tone of my sub any? thanks for the sudjestions so far i'll look into those.
