When a home theatre speaker is placed on wall hanging on nails it not only restricts the position of your speakers but also causes loss in sound due to loose fitting. The home theatre experience can be brought to life when the speakers are positioned at your ear level. Also the arrangement needs to be in specific angles for 2.1, 5.1 and 7.1 Systems. But once you hook the speaker on those nails or any non-adjustable mount your seating position is going to be fixed and this where speaker mounts fall in to place. Give an edge to your sound system with these classy looking mounts. The Home Theater HT 55 series was developed to provide compatibility with the size and mounting requirements of all new Home Theater systems.
