Unfortunatly, that is how most "home theatre in a box" systems sound combined with improper calibration.
All the speakers should be crossed over at an average of 80hz to the sub woofer to handle the low end. LFE is non-directional, so you shouldn't be able to tell where it is coming from.
Concerening mutlichannel music, many like the QS8s, but direct radiating speakers are suggested. Such as the M2 or M3.
The M3 has a little more umph than the M2 does.
I do not currently do any multichannel listening, perhaps others will chime in.
