The M2D-Sub compact subwoofer has an
operating frequency range of 28 Hz to
160 Hz with a maximum peak SPL of 138
dB. It is primarily intended as a compan-
ion sub-bass unit for integration into an
M2D compact curvilinear array system
for small-to-medium sized applications.
However, it is perfectly suited to general
use where powerful low frequency aug-
mentation is desired. In combination with
M2Ds, M2D-Sub extends the overall system
power bandwidth and frequency response
to 30 Hz. External dimensions are equiva-
lent to two M2D cabinets. QuickFly rigging
allows the M2D-Sub to be flown or ground-
stacked in multiples or in combination with
M2Ds.

The trapezoidal, vented M2D-Sub enclosure
is constructed of multi-ply hardwood and
coated with a textured black finish. Integral
metal grilles protect the drivers. A weather-
protected version is available with custom
rain hood to protect the electronics.
limiting technology aids driver protection,
minimizes power compression, protects
drivers from over-excursion under high
peak power conditions and permits high
constant output. The M2D-Sub is self-pow-
ered and includes an integral two-channel
class AB/H complementary MOSFET power
amplifier with 2250 watts total burst capa-
bility. The M2D-Sub’s Intelligent AC™ power
supply affords automatic voltage selec-
tion, EMI filtering, soft current turn-on and
surge suppression. Phase-corrected active
processing circuits help maintain excellent
performance and reliability, and the high
common-mode rejection of the laser-
trimmed differential input permits long sig-
nal runs through a simple shielded twisted
pair cable. The amplifier, control electron-
ics and power supply are integrated into a
field-replaceable module.
The optional QuickFly MG-2D multipurpose
grid allows either flying or ground stacking
various combinations of M2D and M2D-Sub.
Up to 16 M2Ds (or the equivalent weight of
M2D and M2D-Sub) may be flown with a 7:1
safety factor. Up to eight M2Ds, four M2D-
Subs or six M2Ds and one M2D-Sub may be
safely ground stacked.
Meyer Sound’s RMS™ remote monitoring
system is fitted as standard and provides
comprehensive monitoring of system
performance parameters over a Microsoft
Windows® network.
The M2D-Sub is fitted with two 15-inch, 4-
inch voice coil cone drivers incorporating
lightweight neodymium magnet structures.
Each driver is rated at 1200 AES watts (see
