I am new to the home theather world (replacing two huge speakers I got in 1993). I am purchasing a Pioneer VSX-1014TX receiver and want some speaker suggestions. My wife and room (18'x14') require small speakers. I want a typical surround sound system (2 fronts, center, & 2-3 rear). I've looked at the Infinity TSS450 and TSS750 and the Harmon Kardon HKTS 7, but would like additional suggestions or comments on the above speakers systems. Thanks.
