Pros and cons:
I have this connected to a XBR49X850B.
Connected to a Directv mini-genie, loses sound over HDMI.
Tinny, too much treble.
Subwoofer bandpass frequency too high, gets, "woofy". About what you might expect from an inexpensive plastic sub.
Sounds a hell of a lot better than the crappy speakers in the TV, which was the whole point.
I've had it since the post-christmas sales, for the black Friday sale price.
