Panasonic SC-HTB15

Pros: Good subwoofer and speaker sound quality
Supports ARC interface and Viera Link
Lots of positioning options

Cons: Wish the subwoofer was wireless

Summary: I purchased this at a very good price because at the time of purchase the HTB20 was already out. The speakers can be positioned in a number of ways. You can split them up and stand them on the left and right of your TV. You can combine them into a horizontal sound-bar style configuration and you can also mount them on a wall (which is what I did) in both aforementioned configurations.

I paired the speakers with a ST50 TV and took advantage of Viera Link which means I can control this device with the TV remote. It will also automatically turn on and off as the TV turns on and off.

The sound system is great for watching movies and gaming. Overall, great sound for a decent price.
