Transducer Technology
EV is known globally as a pioneer and leader in transducer designs for professional loudspeaker
systems. The result of an ongoing multi-million dollar R&D project, EV’s groundbreaking DVX woof-
er series sets a new benchmark for performance, high SPL output and low distortion. DVX motor
structure and suspension is optimized for very linear movement using state-of-the-art development
tools, such as computer simulation software for dynamic finite element analysis (Dynamic FEA).
In conventional woofer designs, high power signals with peaks up to and beyond 100V create a
wide variation in the magnetic field, disturbing the linear movement of the voice coil and resulting in
audible distortion. Unique DVX motor geometry greatly reduces these changes in magnetic flux,
reducing harmonic distortion up to 20dB.
DVX frames are designed with integrated Forced Air Voice Coil Cooling™. The movement of cone
and voice coil forces air inside the woofer, taking heat away from the voice coil and exhausting it
thorough the pole plate. This results in drastically cooler operation and reduced power compres-
sion, so DVX can provide continuously higher output. The asymmetric suspension of DVX provides
a perfectly harmonic system that eliminates typical loudspeaker resonances that can cause audible
sound coloration. This process of Ring-Mode Decoupling (RMD) reaches back to the late 90’s and is
already integrated in DVX. Computer modeled die cast frames are optimized to be rugged and light-
weight, while specially cold forged magnets provide higher sensitivity and additional weight savings.
Offering an unprecedented level of sonic clarity, dynamic capability, very high output and long-term
endurance and reliability, the amazing performance of DVX woofers needs to be heard to be believed.
Combined with the output potential of manifold technology , DVX is the base for the outstanding
acoustical performance of Phoenix.
With every excursion,
cool
air is drawn through the
voice coil, removing heat. This significantly reduces power
compression, resulting in higher long-term SPL.
