Just upgraded my HT from an HTIB to a real setup. Samsung Blu ray BDC5500, 50" Samsung Plasma, Onkyo HTRC160 receiver, Monitor 50's up front, CS1 center, PSW10, Monitor 30's rear and have an old pair of Bose little cubes that I will either use for the front height or surrounds. Will I notice a difference if I put them as the front highs or on the side walls as my surrounds? Another issue with these is I really have no way to hide the wire. Dont want to go through the walls, have no way to go through the ceiling, and no carpet.
