•Revel C25 中央聲道 規格表

C25
The C25 is a true full range 2-way 5.25” center channel loudspeaker that was designed to be the true acoustical anchor for the entire system. It will deliver an impressive combination of wide frequency range, uncompressed dynamic range and low distortion across the entire audible spectrum.

High frequency response is supported by 1 inch aluminum dome tweeters that were derived from Revel’s Performa3 series. Low/Mid range frequency response is supported by 5.25” Aluminum cone woofers featuring low-distortion motor-structures for greater clarity and accuracy with improved sensitivity and output capability.

The patented wave guide design improves tweeter to woofer blend and significantly improves off-axis response for consistent performance over a wide listening area. In doing this we sacrificed no details by making sure no fasteners were visible allowing the speaker to show enhancing smooth lines of the cabinet and magnetically attached grilles. To finish the enclosure, we selected high gloss black and white finishes to highlight the features of this beautiful speaker.

IN A CLASS BY ITSELF
The RevelR Concerta2 series of loudspeakers combines elegant design and superb finish quality with the best-in-class sound quality for which Revel is revered. Revel created the Concerta2 Series without sacrificing sound quality, beautiful design, or construction quality to meet lower price points. Instead, Revel engineers used the results of years of research to create superior waveguides, optimized transducers, new crossover topologies and novel port designs. These ingenious advances allowed Revel to create a series of loudspeakers that truly live up to the unmatched sound quality for which Revel is known.

LOW-RESONANCE TWEETERS
Typical tweeter magnetic assemblies have a minute space behind the dome that causes a high fundamental mechanical resonance. In designing the Concerta2 series, this challenge was met head-on by Revel engineers. They created a tweeter with a mechanical resonance that is well below the operating band — which ensures linearity and consistency in the crossover region. To do so, a large cavity behind the magnetic assembly was designed, which is vented around the perimeter. This, along with a compliant diaphragm surround, sets the mechanical resonance frequency to a low 800Hz compared to a typical 1.5kHz found in similarly priced speakers. These advances allowed the tweeter/midrange crossover to be set an octave lower thereby improving the critical system directivity.

TWEETER WAVEGUIDE AND
ACOUSTIC LENS
Revel’s unparalleled research teams have discovered that faroff-axis sound that is reflected from side walls is interpretedby our brains in combination with the direct sound fromthe loudspeaker to the listener—we do not differentiatebetween the two. This important advance in psychoacousticknowledge means that the far off-axis response is justas important as the direct sound, and is therefore animportant part of every Revel design. Our sophisticated highfrequency “waveguides” match the off-axis response, ordirectivity of the tweeter and the midrange throughout thecrossover region. Double-blind listening tests have revealedthe importance of this refinement—making the differencebetween what is clearly a “mechanical reproduction” and theseamless sound of real music.

WOOFER
Revel engineers utilize state-of-the-art computer modeling tools during transducer design to optimize everything that affects performance—from the cones to the voice coils, surrounds, the magnetic system and even the “spiders” — the brownish corrugated disc in the rendering to the right. Laser-based analysis of the resulting prototypes confirms ideal symmetry, which results in lowed distortion and cleaner sound quality. Micro-Ceramic Composite (MCC) cones insure ideal piston-like performance, eliminating resonances that would otherwise color the sound.

BEAUTIFUL, HIGH-PERFORMANCE ENCLOSURES
A novel technique of cabinet construction was used to create Concerta2 enclosures that are not only beautiful, but also have rigid, curved side wallsplus extensive bracing that results in a strong and inert enclosure. This ensuresthat the enclosures do not contribute coloration to the sound. The attractivedesigns are available in a luxurious high-gloss white or high-gloss black finish,have magnetically-attached grilles, and have no visible fasteners. These upscalefeatures are typically seen only on far higher-cost loudspeakers.

HIGH EFFICIENCY, HIGH OUTPUT TOWERS
Both the F36 and F35 floorstanding loudspeakers have a woofer-midrange that reproduces the full low frequency range inconjunction with two dedicated woofers. This architecture greatly increases the cone surface area, resulting in a remarkablesystem sensitivity of over 90dB. These towers are therefore an ideal match for a wide range of amplifiers, including verymodestly-powered receivers.

LATEST GENERATION PORT DESIGN
The Concerta2 series uses a patented Constant Pressure Gradient (CPG) technology in the port design. These newports are designed such that the inner wall of the port iscontoured, allowing the change in pressure along the axisof the port from inlet to outlet duct to be kept substantiallyconstant. This design reduces the compression, or changein sound at different volumes that result from other portdesigns, and optimizes both the output capabilityand distortion.
