About the M12

Thank you for purchasing the Revel
Concerta M12 Loudspeaker. A two-way
monitor, the M12 delivers outstanding
accuracy, low distortion and maximum
output across the entire frequency range.
The Concerta M12 is suitable for use in a
bookshelf, built-in to a custom cabinet, or
placed on a pedestal stand. Two propri­etary transducers, a sophisticated filter
network, and an acoustically inert cabinet
allow the M12 to achieve acoustical preci­sion and performance worthy of the most
demanding home entertainment systems.

A two-way design, the M12 transducers
effectively cover a wide frequency spec­trum. A 6.5-inch (165mm) woofer delivers
highly refined midrange frequencies and
surprisingly extended low frequency
response. A 1-inch (25mm) dome tweeter is
mounted in a Controlled Acoustic
Impedance waveguide which dramatically
improves off-axis response. The tweeter
accurately reproduces high frequencies well
above audible levels.

Combining superior form and function,
the M12 transducers feature a distinctive
design that allows for smoother frequency
response. The woofer cone and tweeter are
constructed with Organic Ceramic
Composite cone material to reduce distor­tion. The spiders are constructed with a
high-strength Nomex/cotton blend with
optimized geometry for increased linearity.

The M12 woofer features a ceramic motor
system with magnetic shielding to prevent
interference with CRT video monitors.

The woofer is built with a butyl rubber sur­round for large, linear excursion capabili­ties. The woofer also includes round copper
wire voice coils wound on 1-inch (25.4mm)
Kapton® bobbins which enable high
power handling.

The tweeter dome is under-hung with cop­per-clad aluminum wire for low distortion.
The tweeter’s Neodymium magnet contains
Ferrofluid® which helps to achieve high­power handling with reduced compression.
Magnetic shielding prevents video monitor
interference.

A high-order filter at 2.5kHz optimizes
loudspeaker on-axis and off-axis response,
helping to assure smooth response and
timbral accuracy. Gold-plated binding
posts accommodate heavy-gauge speaker
cable. If desired, the M12 can be placed on
a pedestal stand to optimize its perform­ance.

The M12 cabinet is constructed with medi­um-density fiberboard (MDF) walls to
reduce cabinet-induced colorations.
Threaded inserts on the bottom of the cabi­net accomodate screws for secure fastening
to the optional pedestal stand.

Since 1996, Revel has stood at the forefront
of loudspeaker design and performance.
Backed by Harman International’s exten­sive research and design facilities, the
Revel Concerta Series Loudspeakers benefit
from cutting-edge development tools. A
multi-channel listening lab provides for
double-blind listening tests. A laser inter­ferometer enables detailed driver and cabi­net analysis. Multiple large anechoic
chambers provide for precise tests and
measurements. Finite element analysis
allows for advanced loudspeaker modeling.
A stereo lithography apparatus provides
tight tolerances.

Adding to the proud lineage of Revel’s
Ultima and Performa Series Loudspeakers,
the Concerta M12 solidifies Revel’s reputa­tion as the leading designer and manufac­turer of high-quality, high-performance
loudspeakers.
