I know there are several threads covering the surround-sound audio question. But specifically, I'd like to use my L100's as front left/right speakers. I also have a spare set of L100's that could potentially be used as rear left/right (This is a 7.1 environment). What do you suggest for the center, if anything? Also , how about for the sides? This would also be used for home cinema. I've made the tentative decision not to use a subwoofer, for obvious reasons. Thanks.
