INTRODUCTION 
With an operating frequency range of 28 Hz to 160 Hz, 
the dual 15-inch M2D-Sub loudspeaker complements the 
M2D loudspeaker in reinforcement applications requiring 
extended low-frequency headroom. 
The M2D-Sub loudspeaker affords 138 dB SPL peak output 
capability. It employs two Meyer Sound ferrofluid cooled, 
back-vented drivers each featuring a 4-inch voice coil with 
a lightweight neodymium magnet structure. Each driver is 
rated to handle 1200 AES watts. 
         
NOTE: 
Power handling is measured under 
AES standard conditions: Transducer driven 
continuously for two hours with band-limited noise 
signal having a 6 dB peak-average ratio.
An integral two-channel class AB/H complementary 
MOSFET amplifier provides very high burst capability, 
and Intelligent AC performs automatic voltage selection, 
allowing the unit to accommodate worldwide mains 
voltages without manually setting a voltage switch. 
Integral peak and rms limiters featuring Meyer Sound’s 
TruPower
®
 limiting technology protect M2D-Sub 
components from over-excursion and over-heating while 
assuring minimal power compression and maximum peak 
headroom.
The M2D and M2D-Sub loudspeakers are fitted with 
Meyer Sound’s RMS remote monitoring system, allowing 
the full range of operating parameters to be monitored 
continuously over a network using a Windows
®
 computer. 
In addition, both loudspeakers are supported by the Meyer 
Sound MAPP Online
®
 multipurpose acoustical prediction 
program for easy and accurate system design. The MAPP 
Online prediction program allows quick prediction of 
coverage, frequency response, impulse response and 
maximum output of arrayed loudspeakers, and more.
         
NOTE: 
See Chapter 4, “Remote Monitoring 
System,” and  Chapter 5, “System Design 
and Integration Tools,” for more information about 
the RMS monitoring system and the MAPP Online 
prediction program. 
         
NOTE: 
Read this entire manual carefully 
before configuring and deploying your M2D 
and M2D-Sub system. In particular, pay careful 
attention to the sections about safety issues.
