Recommend Me Surround Sound Speakers

[aren]

This is going to be hooked up to a Panasonic 50" 1080p Plasma HDTV. These are the ones I'm looking at:

Klipsch Quintet SL System

Klipsch Quintet III System

Reviews of the Quintet III are great, however, I get a very good deal on the SL (as well as the Quintet III), so does anyone have any knowledge or experience with these?

This might be too late to respond, but here goes....

I just got the Quintet III from Best Buy ($399 usd) and I love them. They sound fantastic to me, but I didn't/don't have a lot to compare them to.

If I didn't already have a subwoofer (Solid Solutions PB100), I wouldn't have got these. I'm sure glad that I did, though. They feel solid and sound great. Believe it or not, one of the big factors for getting these were the built-in stands that are shelf- or wall-mount with plenty of rotation.
