From the company that produces “The World’s Best

Loudspeakers,” Revel introduces the Concerta series, a family of

loudspeakers that sets the standard for acoustical accuracy com-

bined with impressive value. Borne of the technique and technolo-

gy of Revel’s Ultima and Performa loudspeakers, Concerta has

been developed with the same stringent attention to musical hon-

esty and manufacturing precision that are Revel hallmarks. All

Concerta models are designed to work together harmoniously,

whether for a two-channel music system or a multichannel music

and home theater surround system.

THE LISTENING LAB

Revel makes the most exhaustive measurements of loudspeaker

performance in the industry. We have developed measurements

that are unique in their ability to meaningfully portray sound quali-

ty. However, Revel knows that the final authority for loudspeaker

accuracy must be the listener’s satisfaction. That is why we not

only measure our loudspeakers carefully, but more importantly, we

listen to them exhaustively in our unique and proprietary Multi-

channel Listening Lab (MLL). This remarkable listening environ-

ment is equipped with numerous pneumatically-positioned

loudspeaker mounting platforms.

Two loudspeakers, even of identical make and model, will sound

different according to their particular placement within any given

room. During the listening process, the loudspeaker samples being

compared are quickly repositioned via moving platforms so that

the placement within the room is identical for each, which allows

the listener to more clearly evaluate each speaker’s performance,

and not be influenced by its position in the room.

To further improve the auditory scoring accuracy, the loudspeakers

being compared are visually obscured by an acoustically transpar-

ent but optically opaque scrim. No one in the room is ever aware of

3

which loudspeaker is playing, as the MLL computer controlled sys-

tem randomly decides which speaker is selected. This double-blind

listening and scoring system completely removes visual and brand-

related bias from the listening process, ensuring that the listeners

only evaluate and score based upon what they actually hear, and

nothing else.

This guarantees that any given Revel loudspeaker is honestly com-

pared – to other Revel models and to competitors’ offerings, and is

unique in the industry.

UNIQUE DESIGN TECHNOLOGIES

Revel engineers have access to the broad array of Harman

International’s loudspeaker design and development technologies.

A Laser Interferometer measurement system is used to rapidly scan

a driver’s diaphragm even when it is operating at extremely high

frequencies, providing a visual confirmation that the radiating sur-

face remains pistonic and does not exhibit signs of breakup. The

laser interferometer is also used during speaker cabinet develop-

ment, to ensure that the cabinet remains acoustically inert and

does not radiate unwanted acoustic energy.

Our in-house stereo lithography system allows the engineers to

create prototype mechanical parts directly from our computer

aided design programs in a matter of hours, shaving weeks and

months off the driver development process. We also have three

separate anechoic chambers, whereas most speaker companies

have none.

EXCLUSIVE DRIVERS

The Concerta loudspeaker drivers feature our exclusive Organic

Ceramic Composite (OCC) cone and dome technologies, which

offer the ideal combination of low mass and high rigidity. This

ensures that the diaphragm remains pistonic over the entire oper-

4

ating frequency range, reducing distortion to vanishingly low lev-

els. Concerta tweeters feature under-hung voice coils, Ferrofluid®

magnetic damping fluid and advanced neodymium motor sys-

tems, all contributing to optimized performance. These sophisticat-

ed tweeters are designed around our proprietary Constant

Acoustic Impedance (CAI) waveguide technology, which provides

ideal acoustic loading over the tweeter’s operating frequency

range along with increased efficiency and optimized dispersion.

Concerta midrange and woofer drivers feature oversize magnetic

assemblies, along with flat spiders to optimize linearity and die-cast

alloy frames for maximum rigidity and cooling efficiency, and are

equipped with real butyl rubber surrounds. The Concerta B12 sub-

woofer features a massive magnetic motor structure, an aluminum

cone, and is equipped with a CAD-optimized high compliance

butyl rubber surround spider for low distortion and long excursion.

All drivers are magnetically shielded for placement near a video

monitor.

The internal dividing networks feature steep slope, high order fil-

ters and are equipped with extremely tight tolerance components.

The F12, M12 and C12 all feature 3% tight tolerance crossover

components, while the S12 surround speaker features 5% tight

tolerance components. The use of such tight tolerance crossover

elements ensures outstanding unit-to-unit sonic consistency and

matching to the production reference standard.

Concerta cabinets are constructed of acoustically dense MDF, and

feature internal bracing for added rigidity and freedom from cabi-

net-induced colorations, and are available in your choice of cherry,

maple, or black cabinet finishes.

The following pages introduce you to each member of the

Concerta loudspeaker family.

Whether the principal loudspeakers

in a stereo music system, or the main left

and right loudspeakers in a multichannel

surround system, the Concerta F12 serves

impeccably with Revel's signature timbral

accuracy and astonishing dynamic range.

The svelte cabinet occupies less

than one square foot of floor space, yet

the F12 produces a broad and expansive

sound stage along with an explosive

dynamic range with a four driver, three

way design that incorporates Revel's

Organic Ceramic Composite (OCC) dia-

phragm technologies.

Low frequencies, all the way down

to the lowest registers at an impressive

28 Hz (-10 dB), are reproduced by a pair

of die-cast frame OCC 8-inch cone

woofers which are equipped with high

current voice coils, distortion-reducing

butyl rubber surrounds and flat high

excursion spiders. The essential midrange

frequencies are reproduced by a 51⁄4-inch

driver featuring a die-cast frame and OCC

cone to eliminate coloration from reso-

nances.

For transparency and delicacy, the

highest frequencies emanate from the 1-

inch OCC dome tweeter that is housed

within the CAI-optimized waveguide

assembly, which provides both optimum

dispersion as well as increased dynamic

range. This carefully optimized dispersion

precisely matches the 51⁄4-inch midrange,

resulting in unprecedented seamlessness

and coherency. The tweeter's neodymium

magnetic assembly features an under-

hung voice coil which ensures linearity

and low distortion.

Internally, the F12's thick MDF cab-

inetry is substantially braced for additional

rigidity, and the steep slope, high order

crossover features the industry's tightest

3% tolerance components for outstand-

ing consistency and matching with the

design reference standard.

The F12 is equipped with bi-amp

capability. All of the F12 drivers are mag-

netically shielded to allow placement near

a CRT video display. The F12 is available

in your choice of cherry, maple or black

cabinet finishes.

The M12 monitor loudspeaker

delivers outstanding timbral accuracy over

a remarkably wide frequency range that

belies its diminutive cabinet size.

The 61⁄2-inch woofer features a rigid

Organic Ceramic Composite (OCC) cone

that is coupled to the die-cast frame via a

high excursion butyl rubber surround, and

includes a flat spider that further aids lin-

earity and reduces distortion. Utilizing an

oversized ceramic magnet, the M12

achieves impressive low frequency

response all the way down to 41 Hz

(-10 dB).

The M12's 1-inch OCC dome

tweeter is mated with our proprietary

“Constant Acoustic Impedance" wave-

guide technology, which provides opti-

mized dispersion over a wide listening

area and reduces distortion and dynamic

compression at elevated listening levels.

This carefully optimized dispersion pre-

cisely matches the 61⁄2-inch woofer, result-

ing in unprecedented seamlessness and

coherency. A powerful, yet compact

neodymium motor system maximizes

sensitivity, while Ferrofluid magnetic cool-

ing fluid contributes to realistic musical

dynamics.

The steep slope, high order

crossover features ultra-tight 3% preci-

sion tolerance components, assuring out-

standing consistency and matching with

the design reference standard.

The M12 monitor loudspeaker is

magnetically shielded, which allows

placement near a CRT monitor in a home

theater system.

Constructed of thick MDF and

internally braced for added rigidity, the

M12 cabinet is equipped with threaded

inserts on the bottom panel to accommo-

date screws for secure fastening to the

optional pedestal stands. Gold plated

binding posts can accept heavy gauge

speaker cables and connectors. The M12

is available in your choice of cherry, maple

or black cabinet finishes.

C12Center Channel

C12 in cherry on optional stand

11

Quite possibly the most important

component of a multichannel surround

sound speaker system, the center speaker

provides most if not all of a movie's spo-

ken dialog, as well as music and sound

effects, and is equally critical with multi-

channel surround mixes as well. The

Concerta C12 center loudspeaker is

designed to ensure that everything in the

critical center channel is audible and con-

sistent over a wide listening area, with

exceptional dynamic range with no audi-

ble compression during high volume pas-

sages.

Equipped with a quartet of sophisti-

cated drivers with Organic Ceramic

Composite (OCC) diaphragms, the C12

features two 61⁄2-inch die-cast frame

woofers with high power handling and

extended low frequency response all

the way down to a remarkable 50 Hz

(-10 dB). The critical midrange frequen-

cies are handled by a die-cast frame 4-

inch driver that is housed within its own

sub-enclosure, while the high frequencies

are effortlessly reproduced by a 1-inch

OCC dome tweeter with a neodymium

magnet that is housed within the

Constant Acoustic Impedance flared

waveguide assembly for optimum disper-

sion, efficiency and dynamic range. All

drivers are magnetically shielded for com-

patibility with CRT displays that can be

affected by close-proximity magnetic

fields.

The steep slope, high order cross-

over is equipped with ultra-tight 3% tol-

erance components to ensure

outstanding consistency and smooth

tonal balance over the entire frequency

range. The C12 cabinet is constructed of

thick MDF with substantial internal brac-

ing for added rigidity, and is equipped

with a rear-mounted adjustable tilt system

that is ideal for above-the-monitor place-

ment.

An optional stand is available for

floor placement, which positions the C12

at the desired height with a slight upward

tilt for optimum coverage over the listen-

ing area. The C12 is available in your

choice of cherry, maple or black cabinet

finishes.

13

A truly multi-faceted performer, the

Concerta S12 surround loudspeaker can

be configured for different dispersion

characteristics according to the type of

surround effect desired as well as for dif-

ferent placements within the listening

room. Featuring a pair of woofers with

Organic Ceramic Composite (OCC) cones

as well as a pair of OCC dome tweeters

with neodymium magnets along with our

proprietary Constant Acoustic Impedance

technology, the S12 offers unparalleled

surround sound versatility.

Three dispersion modes are user-

selectable via the front panel switch.

Choose Dipole mode for side-of-listening-

area placement, where the two driver pair

sets operate in reverse phase mode, which

minimizes localization while providing

broad surround sound dispersion - ideal

for movie surround soundtracks. Bipole

mode provides the best combination of

dispersion and improved localization for

pinpoint surround sound imaging with

SACD, DVD-Audio, DTS® and Dolby

Digital® multichannel music surround

sources. A third Monopole mode allows

the deactivation of one of the two driver

sets, when spot-on imaging is desired,

such as for discrete multichannel pop

music.

For 7.1 systems such as THX

Ultra2®, Dolby Digital EX® and DTS ES®,

the S12 also features dual separated

crossovers and two pairs of speaker input

terminals. By removing the shorting straps

on the binding post pairs, one S12 can

function as two distinct surround loud-

speakers in a single enclosure. This unique

capability allows the use of one S12 to

function either as both left and right rear

surrounds, or as both a side and rear sur-

round speaker. The Concerta S12 can

therefore provide a unique solution for

7.1-channel systems in tight spaces.

The S12 is available in your choice

of black or white finishes, with matching

grilles.

B12Subwoofer

15

The Concerta B12 subwoofer deliv-

ers accurate and authoritative deep bass

from a surprisingly compact enclosure

that features a die-cast frame high excur-

sion 10-inch driver with a massive mag-

netic motor structure mated with a

powerful 650 watt amplifier.

The B12's woofer is equipped with

Revel's Symmetrical Field Gap technology

that more precisely focuses the magnetic

energy between the three-inch high cur-

rent voice coil and the surrounding pole

pieces, minimizing distortion, even at high

output levels. The CAD-optimized butyl

rubber surround, flat spider and alu-

minum cone can withstand even the most

punishing high-level low frequency con-

tent.

Any subwoofer's performance will

be, to at least some degree, affected by

the room acoustics that it is placed in, and

where in the room it is sited. Certain low

bass frequencies may be adversely affect-

ed by standing waves caused by room

modes, where some frequencies are

exaggerated (peaks), while others might

be diminished (dips). To tame the sub-

woofer's response in the listening room,

the B12 features a parametric Room EQ

function, with controls for frequency, level

and bandwidth to tune out room-induced

response anomalies.

In addition, the B12 also features

variable crossover frequency and level

controls (which can be bypassed), and a

phase switch to ensure a seamless blend

between the subwoofer and the main

loudspeakers. Together, these controls

ensure optimum performance in virtually

any system configuration, whether a

stereo music system or a multichannel

surround sound home theater system.

The B12's cabinet is constructed of

thick-walled MDF with internal bracing

for rigidity, and is equipped with rubber

feet for use on hardwood or tile floors,

and comes with supplied spikes that can

be installed for use on a carpeted floor.

The B12 is available in your choice of

cherry, maple or black cabinet finishes.

SPECIFICATIONS

SensitivitySensitivity provides an indication of how much amplifier power is required for theloudspeaker to play at satisfactory volume levels. Conservatively rated specifica-tions indicate good sensitivity and denote that Revel Concerta loudspeakers do notrequire huge amplifiers to achieve realistic levels in all but the largest rooms. 4 pianechoic represents testing done in a true anechoic (echo or reflection-free) listen-ing environment, while 2 pi anechoic indicates the use of a chamber with one solidsurface (suitable for on-wall loudspeakers).

Recommended amplifier power rangeWhile it is impossible to know the characteristics of a listener’s room acoustics ortheir listening habits, the recommended amplifier power range provides rough guid-ance for suitable amplifiers. All power ratings are at 8 Ohms, and with unclipped(undistorted) music or film sound sources.

ImpedanceImpedance indicates whether the speaker system presents a “hard” or “easy” loadon the amplifier. Revel Concerta loudspeakers are designed to be "easy" loads formost any modern amplifiers. All Concerta loudspeakers are suitable for use witheven modest amplifiers or receivers, including those that specify the use of "8 Ohmloudspeakers."

Filters (crossover)Steep filter slopes ensure good acoustical behavior in the crossover regions, with aminimum of acoustical interference, along with low distortion and wide dynamicrange. Revel filters feature specially selected components. The F12 includes a pro-vision for bi-amping or bi-wiring. The S12 features dual separated crossoversallowing it function as a dipole, bipole, or monopole loudspeaker. Each S12 canalso function as two distinct surround loudspeakers in a single enclosure.

Frequency responsesIn-room response is a breakthrough measurement that, in a single curve, closelycorrelates to sound quality and has been a goal of loudspeaker engineers for years.Research, and simple observation, reveals that ubiquitous “on-axis” responsecurves often cannot distinguish between two loudspeakers with radically differentsound quality. This specification for Revel loudspeakers is even more powerfulwhen it is taken in context with the other measurements presented here.

Studies have shown that the -10 dB low frequency extension specification is theone that best correlates to controlled listening tests. At low frequencies, mostloudspeaker/room combinations exhibit significant “room gain,” which is anincreasing rise in level as frequencies decrease. In addition, the -10 dB specifica-tion reflects the steepness (i.e., order) of the low-frequency roll-off, which is notsignificantly indicated in -3 dB specifications.

Bandwidth indicates the range of frequencies reproduced by the loudspeaker. Thefrequency at which the amplitude is down 6 dB relative to the average level isspecified at both low and high frequencies.
