M2 monitor
The M2 is designed as d&b’s definitive high performance stage
monitor system. The bass-reflex enclosure is optimized for minimal
air compression and houses two 12" LF drivers. It is actively
crossed over and powered by both channels of the d&b D12
amplifier, using SenseDrive for the low frequency channel. The
1.4" exit HF compression driver has a compact but extremely
strong neodymium magnet assembly operating into a very
low distortion waveguide oriented horn, optimized for monitor
applications. The component configuration permits the use of an
extremely low profile cabinet which achieves a constant directivity
from an unusually low frequency of 600 Hz upwards with a
nominal dispersion of 45° x 60° (h x v). Together with a cabinet
baffle angle of 40° to the floor, this dispersion offers a realistic
artist listening area starting directly above the cabinet and ranging
quite far upstage.
The M2 bestows its full dynamics across the entire frequency
range without compromising the solo voices or instruments, which
always stay clearly and audibly in front of the mix.
The M2 cabinet is constructed from marine plywood and has an
impact resistant paint finish. The cabinet is protected by a rigid
metal grill backed with an acoustically transparent foam. Two
fittings that accept the Flying pin 10 mm are located on both sides
of the cabinet allowing quick and flexible rigging.
