Summary: I purchased this because of the manufacturers hype about a much more understandable audio speech experience. That just is not so. The unit only has the ability to shift between two listening modes. One is normal, but garbles lower tones.
Summary: With 2 Bose solo boxes, you need 2 HDTVs in your home. Buying 2 separately means more money but buying 2 for one can mean a little less here. Both systems work well and the audio will echo without fail only if you got an HDTV to spare.
Summary: Bought one (not the bundle) and installed it on my Sony TV. Note that this is a fairly large unit. It is about the size of a stereo amp. It is designed to have the TV sit on it so it is pretty sturdy. You can mount it over the TV if desired. Sound is really great.
