Sound excellent. One small tear in speaker grill. One area of wood visible without stain. Purchased on Audiogon 3 years ago. Rarely used since that time. Selling because they are larger than I need.
The Revel Performa F52 delivers an impressive combination of wide
frequency range, uncompressed dynamic range, and low distortion across the entire
audible spectrum. Five proprietary transducers, sophisticated filter networks,
and an acoustically inert cabinet allow the F52 to achieve acoustical precision and
performance befitting the most demanding home entertainment systems.
The F52 features advanced woofer and midrange motor structures that include
two high-grade Neodymium magnets placed at the center of the motor structure,
inside the voice coil, for improved magnetic shielding. Inside the motors, black-plated
steel shield cups facilitate heat dissipation for higher power handling. Integrated
aluminum flux stabilization rings minimize modulation inside the motor static gap
flux fields, greatly reducing distortion. Copper rings inside each motor gap
reduces distortion even further. Both rings are optimally sized and placed to maintain
constant linear voice coil inductance with forward and backward cone motions.
Combining superior form and function, the F52 transducers feature a distinctive
design that allows for smoother frequency response. The woofer and midrange cones
are 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 three-way design, the F52 transducers accurately reproduce the entire audible
spectrum. Three 6.5-inch (165mm) woofers deliver highly refined and dynamically
authoritative low frequencies down to the very lowest octaves. Housed in its own
sub-enclosure, a 5.25-inch (133mm) midrange handles critical mid-band
frequencies with natural tonal balance over a wide operating range. A 1-inch
(25mm) aluminum-dome tweeter, incorporating a custom-designed wave
guide, blends perfectly with the midrange and reproduces high frequencies well
above audible levels. The tweeter is vented for improved cavity damping and low frequency
High-order filters at 200Hz and 2.3kHz optimize loudspeaker on and off-axis
response, helping to ensure smooth octave-to-octave balance and timbral accuracy.
Separate woofer, midrange, and tweeter filter boards prevent mutual interference
between filter network components, dramatically reducing distortion over a
wide dynamic range.
Separate Low Frequency Compensation and Tweeter Level switches allow precise adjustment for less-than-ideal listening room acoustics and loudspeaker placement.
Removable shorting straps and gold-plated binding posts accommodate single-wired, bi-wired, and bi-amplified connections.
The F52 cabinet is constructed with 1-inch (25mm) thick walls and extensive
internal bracing to reduce cabinet-induced colorations. Rounded baffle edges minimize
diffraction and optimize off-axis response for smoother high-frequency reproduction.
Adjustable spikes are attached to the bottom of the cabinet for optimal stability,
accommodating installations on tile, hardwood, or carpeted floors. A sonically
optimized grille is also included.
Each F52 is individually hand-tuned during manufacturing to match the production reference standard within a fraction of a decibel, ensuring incomparable loudspeaker-to-loudspeaker consistency.

• 6.5Ω (nominal) • 3.5Ω (minimum @ 373Hz)
Indicates the amount of power the associated power amplifier
must deliver to drive the loudspeaker at reasonable volume
levels. Conservatively-rated specifications indicate moderate
sensitivity, meaning that a massive power amplifier is not
required to drive Revel loudspeakers to reasonable volume
levels in large listening spaces. Indicates whether the loudspeaker
presents a "difficult" or "easy" load on the associated power amplifier.
Combined with moderate phase angles, a minimal impedance
specification of 3.5Ω allows a reasonably designed power
amplifier to drive Revel loudspeakers.
Filter Network • Three-way, high-order
acoustic response @ 200Hz and 2.3kHz
Indicates the acoustical characteristics of the filter network. Steep filters indicate an optimized filter network that produces minimal acoustical interference, low distortion,
and expansive dynamic range. Revel's filter networks are mounted on printed circuit boards with carefully selected components. Woofer, midrange, and tweeter filter boards
are independent of one another. Each includes provisions for single-wired, bi-wired, and bi-amplified connections as well as flexible controls for user adjustments.
Target Response • ±0.5dB from 31Hz to 20Hz
Indicates sound quality in context with the individual loudspeaker's application, considering the acoustical impact of its placement. An ideal response goal, a target response
is not flat at either end of the audible spectrum and is used when the ideal reference is not a flat line.
In-Room Response • ±0.5dB from 33Hz to 18kHz
Indicates sound quality in context with other specifications. A breakthrough measurement, this specification closely correlates to sound quality in a single curve--a long-standing
goal of loudspeaker engineers. In-room response is measured through the use of large
anechoic chambers. The loudspeaker's response is measured every 10 degrees, horizontally and vertically, for a total of 72 response measurements.
The in-room response curve is a prediction of how the loudspeaker would measure in a typical room. Research and observation reveals that ubiquitous on-axis response
curves cannot distinguish between two loudspeakers with radically different sound qualities.
First Reflections Response
• ±0.5dB from 33Hz to 17kHz
Indicates the response listeners hear in relation to the first reflections from walls, ceilings, and floors. This specification indicates that Revel loudspeakers will remain accurate,
even in listening rooms that cast strong reflections.
Listening Window Response
• ±1.0dB from 38Hz to 18kHz
Indicates the on-axis response of the loudspeaker. An improved on-axis measurement, this specification reduces the visual confusion of inaudible interference. It retains full
accuracy without using "spectral smoothing," which results in significant data loss.
• --10dB @ 23Hz
• --6dB @ 26Hz
• --3dB @ 37Hz
Indicates the low-frequency response of the loudspeaker. Studies have shown that the --10dB specification best correlates to controlled listening tests. At low frequencies,
most loudspeaker and listening room combinations demonstrate significant room gain, which produces an increase in levels as frequencies decrease. Unlike the --3dB
specification, the --10dB specification reflects the steepness of low-frequency roll-offs.
