Review on ZVOX AV257 TV Soundbar With AccuVoice Technology And 12 Levels Of Sound Enhancement - Wall Mountable Home Speaker With Alphanumeric Display For Crystal Clear Dialogue, Perfect TV Sound System by Andre Arias

My Dad has been struggling to hear the TV for several years. We had tried an earlier version of this five years ago, the AV200, and returned it. Well, as soon as we hit the correct frequency correction his face lit-up - He could understand the dialogue! And he wants the volume lowered!It has worked so well that he cancelled his hearing aid appointment. This is a sound bar for those that have significant difficulty in hearing the dialogue.
