I have a Sony da50es receiver which has limited bass management. The problem seems to be that the crossover setting for redirecting bass from the mains to the sub is set too high (100 or 120 hz depending on who you talk to). I have mid-size front mains which reproduce bass well except that they choke on the really deep bass put out by 5.1 material. The problem is that if I set my mains to "small" on my receiver, thus redirecting the bass to the sub, I seem to be lacking mid-bass. Movies sound good, but music sounds very thin. If I set the mains to "large", I get much fuller, better sounding bass, but the mains choke on the really deep bass put out by 5.1. My intended solution is to keep my mains set for "large" and use the appropriate capacitor in-line with the speakers to filter out all bass below a certain value, say 75hz. Can anyone tell me whether this is feasible, and if so, exactly what type and value of Capacitor I would need for this purpose. My speakers are 8 ohm.
