I've got a 5.1.4 setup - Sierra 2's across the front and HTM 200s for surrounds & ATMOS ( .1 Rythmik E15) For me, HTM200s are fine in surround duty as I'm not big into multichannel music.
My setup is dual - music & HT, but seems to be more music than movies now a days. So, I am contemplating a pair of the Towers for L/R - any one in the Houston area with a pair that would demo them for me - just to get an idea of how they sound versus my S2's?
