The MK870 is our flagship LCR in-ceiling speaker and is designed for larger theater rooms and high-end systems. Features include an 8" Glass Fiber Woofer, 1" aluminum dome pivoting tweeter and 175 watt power handling. Plus, you can tailor bass and treble up or down thanks to front-mounted contour switches. This is specially handy to fit your different room finishes (wood floor, stone floor, carpet floor, etc.). The MK870 speakers will look great and sound even better for years to come.
