Engineered using proprietary MTX technology and designed for optimal performance in real world applications by their experienced acoustical engineers. Each model is carefully designed from the ground up to offer a level of performance than higher priced competitive product can't reach. The new Theater models offer everything one needs to turn the audio of any mediocre place to watch movies into the complete cinematic experience. With features like pivoting dome tweeter, front mounted tweeter level switch, IR remote knockout, and video shielding on select models in the line, the listener has more mounting location options, more imaging control, and overall better performance. In addition to a variety of 5.25", 6.5", and 8" in-ceiling and in-wall models, there is a specialty LCR for front and center channel applications and an in-wall subwoofer. The 8" in-wall sub adds a tremendous boost to the low frequencies creating a rich, full sound without taking up any floor space.
