Logitech X-540 5.1 Speaker System

The Good points I can mention are:
a) Nice and loud sound (without getting to much technical details of it)
b) Nice Bass as well...
c) The stands ! You can have them in 2 positions and it helps to attach to walls... Really a very good thing about this set.
d) The central speaker stand, that attached to my 22" monitor.. Just perfect..
e) The Matrix feature, where even my notebook (with one way out only) get's a 5.1 sound (computer generated, but is better than nothing !)
