I have debated for two weeks over the best combination for home theater....Sierra LCR w/340's or Sierra LCR w/170's or CMT-340's all around. I'am new to Home Theater and I must admit whatever I have in my room will be the best...because I have nothing else to compare them with. Except I just purchases a Onkyo 706 w/**** Accousticmass 10 5.1 speakers....I dont see how anything could sound better than this(6 inch. cube speaker) for a total of $1500 bucks, but like I say I have nothing else to compare. Someone's review of **** led me down the Ascend Path.....$$$$$$ Ive got some coming!!!!!!!
