ABOUT THE M22
Thank you for purchaasing the Revel
Performa M22 Loudspeaker. Delivering
expansive sound that defies its compact
dimensions, the M22 offers an impressive
combination of wide frequency response,
low distortion, and maximum output. Two
proprietary transducers, a sophisticated
filter network, and an acoustically inert
cabinet enclosure allow the M22 to achieve
acoustical precision and performance
befitting the most demanding home
entertainment systems.
A critical aspect of loudspeaker design,
transducers convert electrical signals into
audible sounds, profoundly affecting
loudspeaker performance. Combining
superior form and function, the transducers
feature a distinctive design that allows for
smoother frequency response. The woofer
cone is constructed with Organic Ceramic
Composite cone material to reduce distortion,
while the spiders are constructed with a
high-strength Nomex blend with optimized
geometry for increased linearity.
A two-way design, the M22 transducers
effectively cover a broad range of frequencies.
Covering well over seven octaves, a 6.5-
inch (165mm) woofer delivers highly
refined mid-range and low frequencies
with incredible dynamic range. A 1-inch
(25mm) titanium-dome tweeter reproduces
high frequencies well above audible levels,
with wide dispersion for open, airy treble.
Separate Placement Compensation and
Tweeter Level controls allow the M22 to
deliver stellar performance under conditions
that require less-than-ideal loudspeaker
placement or listening room acoustics. The
Placement Compensation control provides
ultimate placement flexibility, allowing the
M22 to be flush-mounted in a bookcase or
wall unit or placed on a stand (such as the
optional pedestal stand). A separate Tweeter
Level control achieves precise balancing of
high frequencies for optimal timbral balance.
An advanced woofer motor structure
includes a high-grade Neodymium
magnet placed at the center of the motor
structure, inside the voice coil, for improved
magnetic shielding. Inside the motor, a
black-plated steel shield cup facilitates heat
dissipation for higher power handling. An
integrated aluminum flux-stabilization
ring minimizes modulation inside the
motor’s static gap flux field, greatly reducing
distortion. A copper ring inside the motor’s
gap reduces distortion even further. Both
rings are optimally sized and placed to
maintain constant linear voice coil
inductance with forward and backward
motions.
A high-order filter at 2.2kHz optimizes
loudspeaker on and off-axis response,
helping to ensure smooth octave-to-octave
balance and timbral accuracy. Separate
woofer and tweeter filter boards prevent
mutual interference between filter network
components, dramatically reducing distortion
over a wide dynamic range. For even greater
sound enhancement, the M22 cabinet is
constructed with 0.75-inch (19mm) thick
walls and extensive internal bracing to
prevent cabinet-induced colorations as well
as rounded baffle edges to minimize
diffraction and optimize treble response.
Since 1996, Revel has stood at the forefront
of loudspeaker design. Backed with
Harman International’s extensive research
and design facilities, the Revel Performa
Series Loudspeakers benefit from cutting-
edge tools such as a multi-channel listening
lab for double-blind listening tests; a laser
interferometer for detailed driver and cabinet
analysis; real anechoic chambers for precise
tests and measurements; finite element
analysis for advanced loudspeaker modeling;
and a stereo lithography to provide tight
tolerances.
