Kramer CL-6P 6.5", In-ceiling two-way closed back co-axial passive speaker

The Kramer CL-6P is a 6.5-inch two-way coaxial in-ceiling loudspeaker with a closed back, the size most often specified for general speech and programme reinforcement in an office or classroom ceiling.

It wires low-impedance at 8 ohms or taps onto a 70V or 100V distributed line. Power handling is 30W continuous and 45W peak, nominal sensitivity 88dB SPL, giving 103dB SPL continuous and 105dB SPL peak. It is plenum rated to UL 2043 and UL 1480A. Black and white magnetic grilles are in the box, and the wiring is accessible from the front so a fault can be traced without going above the ceiling.
