Installation
MM2
A serrated swivel mounting bracket with locking nut is furnished for
installing the MM2 and is designed so the speaker can be moved
through an angle of at least 90°. Three mounting holes are present
in the base of the mount.
MM2F
The MM2F is provided with six mounting holes 7/32 inch in diameter
around a 6.625 inch circle, to be installed behind a 6-1/8 inch
diameter hole.
Directional Performance
The directional characteristics of the MM2/MM2F were measured
by running a set of polar responses in a large anechoic chamber.
The test signal was 1/3-octave-band-limited pseudo-random pink
noise centered at the ISO standard frequencies indicated in Fig. 1.
Additional typical data is provided in Figure 2 that indicates 6 dB-
down beamwidth versus frequency for the MM2/MM2F.
Frequency Response
Figure 3 shows the axial frequency response of the MM2/MM2F. It
was measured at a distance of 1 meter, using a swept sine wave.
Low-Frequency Driver Protection
When frequencies below the low-frequency cutoff for the horn
assembly are fed to the driver, excessive current may be drawn by
the driver. For protection of the driver and amplifier, a capacitor in
series with driver is recommended.
For drivers without transformers:
16-ohm driver 25 V - 100 mf
150 Vdc or 150 V non-polarized electrolytic, or two 150 V electrolytics
of two times required value in series, back to back, for 70-volt lines.
