I have an LG 55LW5600 TV and an LG 3D Blu-ray player in a 13.5-by-16 room. The TV is on the long side of the room, so the placement is not optimal, but it allows me to maintain the peace with my better half.
Now, I need a sound system. I think the Onkyo HT-S9400THX system offers good value. Do you like how that system sounds? On the other hand, a large retailer is selling the Polk RTi A5 and RTi A7 at $519 and $629 per pair, respectively. That seems like a good deal, but I would still need a receiver (I'm considering the Pioneer VSX-1121) and a center channel; I do not have a lot of space for surrounds in the back of the room as the couch is against the wall. Would the Polk setup sound just as good with two speakers (say the A7s) versus the Onkyo 7.1 system, considering that it might just be 5.1 or 3.1)? In two or three years, I will develop the basement and move the home theater downstairs to a larger room. Would the Polks be a better long-term investment?
