I got the set in the mail today!

I work nights, so I was sleeping when the UPS guy showed up. Was too busy setting it up, calibrating and testing out music/movies that I never got back to sleep. Luckily, 3hrs of sleep seems to be enough. :P
While I haven't had
too long to play with it all yet, I can say one thing: SVS makes some beastly subs. As many have said before, these subs are BIG and can put out some major bass. Also, its very subtle when it should be while still shaking the walls when its called upon to do so.
Definate thumbs up so far! So far I've tested several Lord of the Rings, Matrix and Star Wars scenes and the 20-39 PCi definately took these movies to another level over my old HTiB onkyo sub. I also tried Dark City's city "tuning" scenes, which were much more subtle, but still added more depth to the scene than before.
I only had an hour or so to test out some music, but i was able to pop in Nine Inch Nails' Downward Spiral (Closer) and their new instrumental album, Ghosts I-IV, both sounded great.
My only issue so far is my furniture's fault: The center is too tall to slide into my TV's stand shelves where my old center was. I have a Sony KDS-55A2000 rear projection set and is rather thick at 19", so the screen isn't flush against the wall like most plasma/lcds. Are there any major downsides with wall mounting the center above the TV, with a downward tilt, instead of below the TV?

I could still mount it below, but it would involve taking out a large glass shelf (permanently) which I don't really want to do just yet.
If I can find some time, I'll try to post some pictures of the new HT setup within the next few days.
