This is a single InCeiling 800 speaker from Canton. We bought this and a whole bunch of in wall and in ceiling speakers from a home installer who was clearing out some of his older inventory. The InCeiling 800 is the “flagship” model of the range and the biggest with a 8.3″ woofer and a 1″ aluminum tweeter. The outside diameter is 11″ but you just need a 9.7″ opening to fit the speaker in. Speaker is a 2-way design with a frequency response of 42 Hz to 30 KHz. Nominal impedance is 8 ohm with a sensitivity of 88 dB. Recess depth in the ceiling should be a minimum of 3.5″.
This is a New Old Stock (NOS) speaker that we just took out for the pics you here and a quick test on its functionality. We have the original box and will securely pack it for safe shipping.
