Titleist:

Good choice of Receiver and Speakers. You will be amazed by the Orbs - recently helped a friend install them - we did Mod 2 for the center and 4 Mod 1s (90/10 movie/music). Once calibrated properly with a decent sub, the ORBs SING!!!!

For the sub, could also look here:

I read a lot about both the Onix X-Sub and the Outlaw LFM-2 - finally settled on the X-Sub recently.

Main reason - similar spec and reviews - X-sub is $100 cheaper. The only problem would be availability. I lucked out - called tAV123 and they had a B-stock unit for $179 (no 30 day trial on that). Love the sub, but am sure that LFM-2 is equally good.

Good Luck.
