Compression Drivers
Electr
o-Voice is one of a handful of professional audio com-
panies that can design high-per
formance compression driv-
ers. Compression drivers are the most difficult audio trans-
ducers to design. Their unique requirements call for
ultraprecise tolerances, state-of-the-art modeling routines,
and exceptionally talented engineering exper
tise. Manufac-
turing techniques ar
e frequently pushed to process limits,
and materials ar
e formed and stabilized with cutting-edge
systems and controls. Each EV compression driver’s parame-
ters are tightly controlled to ensure world-class performance,
thus putting the drivers at the top of their class in every
r
espect.
