The Contractor Series CS-650-RSM summed-mono, in-ceiling loudspeaker features one dual voice coil woofer and two 1/2-inch tweeters, which accept both left and right stereo signals for applications where there’s only enough room for one speaker.

The larger magnets increase efficiency and sensitivity and the powder-coated aluminum grilles will never rust.
