The Insight Series P7m-LCR Soundbar was specifically designed to avoid the compromises inherent in other conventional soundbar “custom length” designs, so you will not have to give up any sound quality just to have it match the width of your TV. The P7m-LCR Soundbar is available in custom lengths from a minimum width of 56.4” (1433mm) and a maximum width of 70.4” (1788mm). The P7m-LCR contains (3) Spherical PMDs for the high frequencies playing down to an amazing 900 Hz, and (4) 4.5″ Woofers to do the low-frequency heavy lifting.
