I knew I had this stuff somewhere but it took a while to find it:
The Klipsch MMTM is a controlled directivity high frequency horn designed for long throw applications. The MMTM's controlled dispersion is ideal for applications requiring high sound pressure levels at long distances and those requiring precise control of coverage patterns.
Frequency range: +/- 5dB 6kHz-16kHz
Sensitivity: 108 dB SPL 1w/1m
Max Power: 40w 124 dB SPL
Nominal beamwidth: H 45 deg V 20 deg
Nominal impedance / minimum impedance: 8 Ohms / 5.9 Ohms @ 18 kHz
Network: Passive 6 kHz hi pass filter with 18 dB / octave cutoff coupled with a notch filter creating a 60 dB / octave slope
Dimensions: 8.25 in H x 10.25 in W x 13.75 in D
Protection: 3 Amp GBB (2 Amp AGC)
