Rated 5 out of 5 by from Great sound, great value! Recently purchased a new LCD TV but was very very disappointed with the sound quality..was really really bad. Was looking for a sound bar and decided on this one. Compared to the others this had good power size and featured that I liked! It sounds awesome! So impressed! Great deal! I made a good decision...
