The Q Acoustics Q-AV LCR65 sound bar will work with televisions with screen sizes between 50" and 65". If you don't want large speakers all around your living room but still want an immersing, high quality acoustic experience from your movies, then you should consider the innovative Q-AV system.
The LCR65 Soundbar is an innovative solution which sits below your television. It is wall mountable, has a bracket to adjust its distance from the wall and expands horizontally to match your television, up to 65" screen size. Also available are the Q-AV table-top stand, floor stand and cantilever wall-mounting bracket, which allow easy mounting of your flatscreen TV and the soundbar at the same time.
