The CCM683 shares most of the high-performance features of the CCM 682, but has a slightly lower maximum amp power of 130W. Like the CCM682, this speaker comes with a 200mm (8in) Kevlar cone bass/midrange driver with a rigid die-cast chassis, a Nautilus swirl-loaded aluminium dome tweeter that pivots for adjustable off-axis treble response, and a three-position EQ switch.
