Hi all, quite a forum you have here! I can't tell you how many things i have learned from lurking here! Anyways I am thinking about getting a Denon 1803 when its avalible later in the year. The only problem is that the sub crossover only goes down to 80hz. My speaker setup so far: Mains: Energy xl:25's (going to get soon) Center: Energy xl:c Surrounds: Energy xl:16's (using as mains right now) Subwoofer: Energy S8.2 My question is won't the 80hz crossover be too high for my speakers (the 25's go down to 43hz, 16's to 50hz, and xl:c to 60hz)? Is there any way to let the xl:25's crossover lower so they can be used to their full potential? If not should I just get another pair of xl:16's to use for mains since I won't be using the lower frequency bass on the 25's anyways?
