Thanks guys for the suggestions. I do have a sub, a HSU (can't remember the model#) Cylinder that can go down to 25Hz. I like this sub very much, but would have liked it even more if the bass was little tighter (any tweaks for improvements?). I have the 150 W amp for the sub and that could have something to do with it.

Love the sound of Maggies (not bi-wired) and would like to buy a Mag center, but, my problem is the shape and size of my room and ofcourse the mags are no room friendly equipment. I have the maggies crossed over at 40 Hz, the builtin speakers in Tos tv (Center) at 80 Hz and my satellite Infinity HTS10 surrounds at 120 Hz. I will play around with the crossovers and see if there is any improvement.

Thanks,
