With a front design that resembles the famous World War II British fighter Spitfire, the MK850 (8-Inch) Ultra Reference in-ceiling speaker packages include a Kevlar woofer for deep, powerful bass response. Known for its high strength-to-weight ratio, Kevlar responds note for note without coloration and allows users to crank up the volume for higher listening levels. Ideal for dedicated home theaters, this in wall speaker also uses a 1-Inch pivoting aluminum dome tweeter that can be aimed toward listening areas to help optimize stereo imaging and coverage.
