Example: 

  5 channel MEME™ Voice control layout.  

Cabinet vibrations are a significant source of distortion and coloration in most loudspeakers.  The primary 
mechanism that generates cabinet vibrations is simple Newtonian action and reaction.  As the driver motor 

(magnet and voice coil) forces the cone to move back and forth in 
order to generate sound, the cone exerts an equal and opposite 
force on the motor.  This force is transmitted through the driver 
frame to the cabinet, vibrating the cabinet walls and coloring the 
sound emitted by the cone.  This effect is most especially prevalent 
in the low frequency drivers where the cone motion is greatest.    

While, the MicroMain26 is built with a massive and well braced 
cabinet, we also tackle the problem at its source by eliminating 
vibrations before they even begin.   This is achieved through our 
innovative force cancellation design.  The low frequency drivers are 
mounted on opposing sides of the cabinet and their motors are 
locked together.  As the cones are driven in and out in opposite 
directions the forces exerted on the motors cancel one another.  
The vibrations never make it to the cabinet because they are not 
allowed to develop in the first place.   

This layout has further benefits.  Since the drivers are locked 
together, the motors and frames function as a massive internal 
metal cabinet bracing.   And because the wavelengths generated by 
the subwoofers are much larger than the speaker cabinet 
dimensions, the subs radiate as if they were a single point source 
located on axis with the tweeter. 

MEME™ Voice Selector Connection: 

The MEME™ Voice Selector switch box is 
connected to the Voice jack of the speaker via any 
standard 3.5 mm stereo phone cable.  The included 
6-way splitter can be used to control the Voice 
Emulation of up to 5 speakers.  Furthermore, the 
input impedance of the Voice jack is very high.  So, 
additional splitters can be daisy chained in order to 
control virtually any number of speakers with the 
MEME™ Voice Selector switch.

Caveat:  Plugging the speaker into different mains 
outlets can potentially cause erratic behavior in the 
MEME™ control.  The safety grounds of different 
outlets can sometimes have ground potential 
differences of a few volts of more.  The resulting 
voltage spread between the grounded chassis of 
various speakers can cause the MEME™ control 
inputs to read incorrect settings or become 
unstable.  Care must be taken with the studio 
mains power and safety ground layout.  If this is a 
concern, please consult a qualified electrician.
