Introduction

Congratulations on your purchase of M-Audio’s EX66 reference 
monitor.  Recording  engineers  and  music  producers  around  the 
world rely on M-Audio reference monitors to ensure their mixes 
are  accurate.    The  EX  series  active  monitors  from  M-Audio 
improve  upon  that  reputation  as  a  top-of-the-line  solution  for 
the most demanding applications.  Engineered to the highest sonic 
standards, the new EX66 monitor addresses the needs of the most 
critical professional users.  Furthermore, the speaker’s “midwoofer-
tweeter-midwoofer”  (MTM)  configuration  is  particularly  well-
suited for multichannel monitoring and for rejecting vertical early 
reflections.

The EX66 represents the culmination of nearly two years of design 
and development.  Custom-tuned cabinets, state-of-the-art driver 
design,  selectable  analog  and  digital  inputs,  and  flexible  digital 
signal processing combine with ultra-clean built-in amplification to 
deliver the best sound available in an active loudspeaker monitor.  
We are pleased to present to you what we believe to be the most 
versatile and accurate audio monitoring solution for professional 
and high-end applications.
