what do you all think about running your main's high pass(>80hz) and your sub low pass(80hz and below). this is how my setup is running right now out of my Lexicon CP-3.

the one positive I noticed from this setup is that I have much more "volume" with minimal distortion, because the signal my bookshelves are being asked to produce, 80hz-20khz, doesn't have the more difficult lower octaves. At the same time I worry there may be a window of midbass missing, but I am less inclined to think this now after listening to my friends Grado RS-1's, which obviously produce the whole range of human hearing with good results.

I'm mainly interested in any negative aspects of running my system this way, but I am open to hearing the positives. Keep in mind this system is used to produce only 2 channel music(no home theater).
