Biamp Systems SDQ5PIR White

We are using these linked to a large flatscreen. The associated wallplate allows automatic switching between sound inputs from the TV and from music players which is perfect and works well for people who are not trained in its use. Just plug and play....
The downsides are: The sound quality is adequate, but not that great. Fine for smallish room and background music. The treble/bass are on up and down buttons, so it is hard to adjust. You can only do it by ear and can't see if you have them set high or low.
