2.4. Dispersion characteristics
The graphs below show dispersion angle over frequency of a
single M6 cabinet plotted using lines of equal sound pressure
(isobars) at –6 dB and –12 dB. The characteristics refer to monitor
operation. When used as a front-of-house system, the horizontal
dispersion corresponds to the vertical plot and vice versa.

Altering the HF horn dispersion
The HF horn can be rotated through 90° for dedicated installation
applications.
Tools required: Torx wrench (#TX25).
Proceed as follows:
1. Disconnect the loudspeaker.
2. Undo the 10 screws holding the front grill and remove the
front grill.

screws at the 12" driver for the desired orientation.
4. Rotate the horn to the desired orientation.
5. Refit all screws and tighten them using a torque setting of
2 Nm.
6. Refit the front grill and tighten all screws using a torque setting
of 4 Nm.
