The Definitive Mythos XTR-50 is the first high performance on-wall speaker whose depth matches that of today's ultra-thin TVs. It is a mere 1.5" deep when mounted on a wall, shallower than many ultra-thin TVs when they are wall-mounted with their factory sanctioned mounting hardware. Beyond its utility and clean modern styling the XTR-50 stands out due to its uncompromising sound quality equivalent to full-size speakers. Definitive's engineers have unleashed their awesome creativity and brain power to develop this revolutionary speaker that has the high definition detail and dynamic range performance of large speakers yet is a mere 1.5” deep. No other speaker complements your ultra-slim television with more style, versatility and sheer performance.
