Revel Performa F52 Speaker System Review

Sonic revelation.
When the assignment came in to review Revel's Performa system, I was more than just a little bit excited. After all, spending time with a Performa F52, C52, S30, M22, and B15A setup is akin to driving a Mercedes-Benz CL600 coupe with every conceivable option when you're accustomed to commuting in a Honda Accord. There's nice, and then there's, "Give me the keys, and get out of the way!" Yes, this would be fun.


Revel enjoys a stellar reputation in the audiophile community. People recognize their products as tools for the discriminating audio enthusiast, and, with the support of parent company Harman International, Revel enjoys the financial support required to remain on the cutting edge. Of particular note, Revel is one of just a few select companies with membership in the far more elite Harman Specialty Group. Make no mistake: Revel is a cream-of-the-crop brand.

Initial Impressions
For this evaluation, I configured a 7.1 system with the C52 center-channel speaker, flanked on the left and right by the F52 tower speakers. Positioned on the left and right sides were a pair of S30s, while the M22 loudspeakers served as the left and right rear channels. I also placed a B15A subwoofer along a side wall on the floor.

The Revel Performa F52 system makes quite a statement in terms of visual impact. The F52, C52, and M22 enclosures were finished in a lustrous maple veneer, with black rear panels and black, fine-mesh cloth grilles in front—creating a very sleek look designed to blend nicely into a variety of living spaces. The B15A subwoofer shared a similar aesthetic, and the S30 surround speakers were finished in black. The S30 is available only in black or white, with matching grilles. All of the other models are available in black ash, natural cherry, or maple.

A Closer Look
The F52 is a five-driver, three-way design that includes three 6.5-inch woofers that utilize the company's proprietary Organic Ceramic Composite (OCC) cone technology for rigidity and low weight. These are coupled with a 5.25-inch OCC cone midrange driver housed in its own subenclosure within the F52 tower. A proprietary 1-inch aluminum dome tweeter, housed in what the company calls the Constant Acoustic Impedance waveguide, reproduces high-frequency content. The enclosure is ported at the rear. There are two sets of gold-plated binding posts mated with shorting straps to facilitate single-wire, biwire, and biamped connections. There are also provisions for adjusting low-frequency compensation (Normal, Contour, and Boundary) and tweeter level (–1, –0.5, 0, 0.5, and 1 decibel). Floor spikes are included.

The C52 center-channel speaker is equally comprehensive. It has dual 8-inch OCC cone woofers, a 5.25-inch OCC midrange driver, and a 1-inch aluminum dome tweeter housed in a Constant Acoustic Impedance waveguide. The rear input panel is essentially a duplicate of the F52's but differs in the inclusion of a placement-compensation switch, which offers flush-mount, stand-mount, and on-top-of-monitor settings.

Designed for wall-mount installation, the S30 enclosure features a high-output 6.5-inch woofer and a 1-inch metal dome tweeter on its largest panel. There are also two 4-inch full-range drivers on the enclosure's side panels. You can configure these enclosures for either dipole or monopole operation. I selected dipole, as I find this setting works best for most program material in many listening environments.

While I was using the M22s for rear surrounds, these enclosures can certainly function as front speakers in a somewhat more modest setup. The driver compliment uses a two-way design that includes a 6.5-inch cast-frame OCC cone woofer mated with a 1-inch titanium dome tweeter. There's a single pair of gold-plated binding posts, complimented by a placement-compensation control (flush or stand mount) and tweeter-level control.

The Performa line's B15A subwoofer is, without a doubt, one of the most highly configurable subwoofers available. The system provides comprehensive control over equalization (frequency, bandwidth, and level) with EQ in/out, plus high- and low-pass contour control with master in/out. There are settings for automatic-on/standby operation, as well as external trigger operation, whereby the subwoofer will switch between film and music contour-response settings—dependent upon whether it detects a steady 12-volt DC voltage (from elsewhere in the system). Furthermore, the B15A ships with an LFO test-signal CD to aid in the setup process.

Performance
For my evaluation, source playback equipment included an Onkyo DV-SP800 SACD/DVD/DVD-Audio player, Parasound's Halo C2 controller, and Sunfire's Cinema 7 amplifier. Kimber Kables fed the front and center-channel speakers, while Monster Cables fed the S30s and B15A subwoofer. XLO Electric cable provided signal to the M22s. The system was calibrated at 75 dB with a C weighting.

I auditioned my classical-music selections strictly in stereo—without the subwoofer. The first movement (Allegro) of Beethoven's Concerto No. 5 in E Flat, Opus 73 (Emperor) was delightful. I was particularly impressed by the F52's ability to handle vast dynamic changes. From pianissimo through fortissimo, the Royal Philharmonic Orchestra's performance was vibrant and highly detailed, and the subtlest nuances of the piano were evident.

Similarly, the first movement (Allegro non troppo) of Lalo's Symphonie espagnole, Opus 21, was inspiring. The solo violin exhibited a presence that is rare in all but the best-performing systems. The system presented the subtleties of Jascha Heifetz's bowing technique with aplomb. Pizzicato string passages sparkled—with just the right amount of bite to the pluck.

On both pieces, stereo imaging was highly detailed and exhibited an almost three-dimensional quality—enabling me to identify placement of various instruments quite easily. Center imaging was particularly impressive. On both the piano concerto and the Heifetz violin performance, I twice found myself checking to make sure I had not accidentally engaged the center-channel speaker.



Switching my configuration to a 2.1 setup for R&B, I listened to a number of tracks from Stevie Wonder's A Time to Love and Anita Baker's My Everything. The B15A subwoofer delivers what I consider to be an incredibly articulate, natural bass response right down to the lowest depths. This subwoofer is a terrific compliment to the F52s. Together, the system delivered vocal tracks that were big and highly intelligible, and the low-mid background vocoder tracks on Wonder's "Positivity" rang clear as a bell. Similarly, Baker's lush, soulful style came through as if she were right there in the room. Simply put, this loudspeaker combination gave new meaning to the term "smooth jazz."

For my surround music evaluation, I listened to an SACD sampler of film composer Jerry Goldsmith's Movie Medleys. While my system was configured for 7.1 surround, this is a 5.1 disc—so the side (S30) and rear surround (M22) loudspeakers received the same signals. During all of the selections, the entire frequency range was evenly represented—with crystal-clear definition at the high end, a full midrange presence, and low-frequency response you could easily feel. The Performas handled sweeping orchestrations from side to side and front to rear beautifully. By the time I concluded with "The Generals," I was ready to stand up and salute.

My surround movie experience was equally exciting. I auditioned selected scenes from The Incredibles—also in 5.1. This was where the C52 center-channel speaker, along with the S30 and M22 loudspeakers, really shined. The C52 did a wonderful job with dialogue and exhibited a real theater-type presence. Meanwhile, the S30 and M22 side and rear surrounds did wonders with the ambient effects. I heard echoes from seemingly everywhere, while nature sounds abounded. During the film's "Missile Lock" scene, filter sweeps danced throughout the entire soundfield with dizzying speed; and, when bombs exploded, the B15A subwoofer shook the room with conviction.

Final Thoughts
I've gushed about sound quality throughout this entire review, and, quite frankly, this system deserves every bit of praise. Like that CL600 coupe, however, performance has its price, and, with an MSRP of $17,583, this Performa setup is clearly not for the economically challenged. Aside from the price, there is an additional issue to consider.

These are demanding loudspeakers that require an equally capable power amplifier to do the system justice. When I backed down on the master level, I felt as though the system really wanted more juice. Thankfully, the Sunfire Cinema 7 had the muscle to handle this—although I could have probably benefited from more power. If in doubt, it's always best to have more power as opposed to not enough. My recommendation: Don't cut corners on your choice of amplifier.

With dramatic visual appeal, beautiful workmanship, and performance that offers a rich, natural sonic presentation with superb dynamic contrast and imaging, the Revel Performa F52 system delivers the goods. I say, if you've got it, flaunt it!

Highlights
• Great imaging, with superb ability to handle wide dynamic contrast
• B15a subwoofer is highly configurable and exhibits extended, controlled bass response

Energy Reference Connoisseur RC-70 Speaker System Review


This is a momentous time for Energy Speaker Systems. Until recently, Energy was one of several brands owned and operated by Audio Products International of Toronto, Canada. (The others included Mirage, Athena, and Spherex.) Now the API brands have been merged into Klipsch of Indianapolis, Indiana, creating a new fusion of Canadian design and American ownership. Energy has also moved their manufacturing to China, where they will have more control over parts, while achieving greater cost-effectiveness. John Tchilinguirian, the longtime lead designer for the brand, has moved on to independent consulting. That makes the Energy RC-70 towers, RC-LCR (serving as center), and RC-R surrounds partly a chapter from a previous tome and partly the first chapter in a new story.

Best Dressed
In the hierarchy of Energy's larger speakers, the Reference Connoisseur speakers sit between the bleeding-edge Veritas line and the more value-oriented C-Series. If you are looking for something less bulky, check out the similar but smaller RC-Mini monitor, the home-design-friendly Take Series, the Act sub/sat systems, or the three in-wall/-ceiling lines, the Veritas Custom, Reference Connoisseur Custom, and EAS series.

A couple I know recently decided to banish all vinyl-clad furnishings, including loudspeakers, from their home. Reference Connoisseur products would meet their standards, with real wood-veneer enclosures in warm cherry, darker rosenut, and black-ash finishes. Pull off the magnetically attached grilles, and you'll see a brushed-aluminum finish on the metal baskets that hold the drivers.

The RC-70 is the largest of the three new Reference Connoisseur towers. The RC-70 looks like a simple rectangular solid, but inside it has full-length bracing that's been computer-tweaked to prevent cabinet resonances from polluting the musical river. Its dual-rear-ported enclosure has enough depth to encompass sufficient volume to produce good bass and a front surface just wide enough to accommodate the girth of its 6.5-inch woofers.

With the inclusion of its 5.5-inch midrange driver, the RC-70 is the only three-way model among the three Reference Connoisseur towers. The woofer and midrange cones are both constructed of Kevlar. Energy specified the thickness and weave and also added a proprietary resin coating. In a move borrowed from the Veritas line, the 1-inch aluminum dome tweeter sits in a separate chamber to isolate it from vibrations.

Aside from the tweeter, the driver mix changes in the RC-LCR and RC-R. The RC-LCR is a left/center/right speaker, although, for this review, I used it only in the center position. Its dual 5.5-inch Kevlar-coned woofers are smaller than those in the towers. Flanking the tweeter in the center of the enclosure is a pair of 2-inch, aluminum cone midrange drivers.

There's no getting around the fact that the RC-70 and RC-LCR don't speak with precisely the same voice. Sticklers may prefer to match the front channels with three RC-LCRs to achieve perfect panning effects and the most even front soundstage. A system with five of them might arguably be the ideal surround system for music. (Steve Guttenberg used three in his Energy review in the June 2006 issue.) However, I didn't regret having two RC-70s in my listening room; it was a brush with greatness.

The RC-LCR's woofers and tweeter reappear on the front of the RC-R surround speaker, with two more of the 2-inch midrange drivers on either side of the enclosure. A switch beneath the grille lets you select between bipole mode (with the midranges in phase) and dipole mode (with the mids out of phase). Next to the switch is something quite rare—a dial that adjusts the output of the side midranges from 0 decibels (off) to 1 dB below the level of the front drivers. Silencing the mids turns the speaker into a monopole unit.

So, you have three options. Monopole operation is best for localized surround effects in the rear of the room (usually my preferred mode for surround music). Bipole operation offers what the manual calls a more "large" and "expansive" sound. And, finally, dipole operation is designed for an "even more expansive" and "even larger" sound. The choice is yours. I went with the dipole setting, as I prefer the fullest possible soundfield.

Second from the top in Energy's subwoofer line, the S10.3 has a 10-inch, front-mounted, hybrid-cone driver with two downward-firing ports. The driver substrate is polypropylene, with deposits of ceramic, glass, and mica to add stiffness. A patented Ribbed Elliptical Surround—which has construction similar to the tower's woofers—allows for excursions of up to 1.57 inches peak to peak. In plain English, you've got a cone that's strong and stiff, suspended in front with a piece of rubber that's strong and supple, being pushed and pulled a fair distance.

The sub's volume control is on its front—where it belongs—and its phase control is continuously adjustable between 0 and 180 degrees (many subs provide just a two-position toggle). If you prefer to set the crossover in your receiver, you'll want to take advantage of the crossover-bypass switch to prevent bass from being routed through two filters when one does the job. The finish is vinyl, not a genuine wood veneer.

The Devil and the Scrunts
The sound that emerged from this hodgepodge of speakers surprised me with its full, rich, easygoing nature. The forthright quality I've always associated with Energy was still there, but a voluptuousness that I had not previously heard from the brand joined it. With my usual 80-hertz crossover, the system generously ladled out lower midrange and upper bass, in contrast to many systems that thin out where the speakers meet the sub. The sub's bass response wasn't quite as taut as that of the speakers. It was more rounded and seemed to detach slightly, although it was also tuneful and performed well under stress.

Some movies pose challenges in dialogue delivery. With the DTS soundtrack of The Devil Wears Prada, fashion fiend Meryl Streep establishes a narrow dynamic range—from deadly sotto voce, down to a near whisper, and finally to an actual whisper. The RC-LCR's vocal delivery, like Streep's, was understated. (This was after I'd set the levels with an SPL meter, with the center channel 1 dB higher than the mains.) To compensate, I hiked the master volume. That enabled me to more easily catch dialogue while literally amplifying surround-rich material like parties, street scenes, and the violent thunking of expensive coats hitting a desk. If the RC-LCR was reticent, it was also commendably smooth, with no excessive sibilance or spit, and with nothing nasal or chesty in its character.

In Lady in the Water, the challenge was not vocal intelligibility per se, but the sheer strangeness of made-up words like "narf" and "scrunt." The center speaker delivered the Dolby Digital–ized consonants just precisely enough for my ears to hear them, but I still couldn't quite believe what I was hearing. When I switched on the subtitles, I saw that the equipment was accurate and that my ears had not been deceived. Then I could settle in and enjoy the whimsical story about an apartment house full of freaks, something the manager and staff of my building could easily relate to. The dramatic scenes didn't make the Energy speakers flinch, although the sound of an automated sprinkler suddenly erupting into all channels did make me flinch.

Miami Vice wraps its combination of action movie, film noir, and cheap, televisionlike visual language in a shroud of disappointingly conventional music and effects. The Energy speakers kept up with all of it, although that wasn't much of a challenge. The Dolby Digital soundtrack showed some early promise when synthesized musical pulses echo the rhythm of a just-concluded shooting. After that, things got dull. Still, to my way of thinking, any movie that features more than one song by Audioslave isn't a total waste of time.

The Sopranos, season six, episode one, features a loud blam that punctuates a key scene (and punctures a key character). The combined explosion from the subwoofer and speakers was suitably shocking.

The Universe and the Saint
BT stands for Brian Transeau, and his work, This Binary Universe, comes with two discs: a CD and a DVD with a DTS surround soundtrack. Naturally, I fired up the latter, and it rewarded me with mostly (but not entirely) abstract images that complemented the mostly (but not entirely) synthesized music. The RC-R surrounds made the most of the busy surround mix. "All That Makes Us Human Continues" was akin to wandering through a brightly lit, glass-enclosed rail station—like, say, Berlin's giant new Hauptbahnhof—while experiencing an inner crisis. The melody morphed from comforting to disturbing, then back again, while shards of light flickered on the screen. The ultimate effect was pleasant but not profound—more on the order of a nice sherry than a stiff single malt.

A piercing harmonica (is there any other kind?) kicks off track one of Robyn Hitchcock's This Is the BBC, a collection of studio-made radio performances dating from the mid- to late 1990s. As I walked from speaker to speaker, with the CD playing in Dolby Pro Logic II, I confirmed that the center was a little reticent compared with the left and right speakers, although none of them was either unduly bright or unduly mushy. This made the harmonica less painful, but it also blunted Hitchcock's edgy voice, slightly defocusing the music's emotional center and opening up the clean, dry BBC mixes. I got a better soundstage when I shut down everything but the two RC-70s. It reminded me that these two towers are as well balanced and satisfying as any I've ever heard in two-channel mode.

Recordings with multiple voices and complex acoustics practically beg for surround treatment, and that's what Bach's St. John Passion got from the Channel Classics SACD release with the Netherlands Bach Society. The performance used a one-voice-per-part arrangement, sacrificing the mellifluous character of a chorus for the specificity of individual vocal performances. There emerged an invigorating and moving contrast between the soundfield's soft, dark, enveloping enormity and the brilliant spotlight hitting each of the voices. The two-disc set includes a hardcover 192-page booklet with lyrics in English, Dutch, German, and French and a rich assortment of sacred artwork. It's expensive but worth it.

Great ideas, well executed, abound in this Energy Reference Connoisseur speaker system. The RC-70 towers provide a powerful combination of high performance, high value, high quality of construction, and understated elegance. As two-channel performers, they are monsters. In the RC-LCR, Energy offers an unorthodox driver array that would well serve every channel in a differently configured system. I loved the versatility of the monopole/ bipole/ dipole surrounds, and I developed a healthy respect for the sub. Wish Energy and their new owners luck—this remains one of the most fascinating brands in the speaker business.

Highlights
• Conventional on the outside; less so on the inside
• Voluptuous midrange and full, rounded bass
• The sub's driver is strong and stiff and is capable of large excursions

Monitor Audio Silver RS 6 Speaker System review


Quality drivers in quality cabinets equals quality sound—at a nice price.

It's easy to find your eyes dazzled, and your mind befuddled, by the outpouring of new speakers over the last few years, particularly those of the nontraditional variety. In-walls, plasma-friendly speakers, and even flat-panel speakers are all the rage with the general public. This is hardly a bad thing—anything that can get people to recognize that the speaker realm extends far beyond the two-dollar paper drivers in their televisions serves a valuable purpose. Many of these people may also come to realize that, at this point, most of these recent unconventional designs embody some degree of compromise, and they hopefully won't fall victim to the dreaded anything-that-is-new-is-better philosophy. It is true that manufacturers are getting more out of unconventional designs than ever before. But, generally speaking, the best speaker sound still comes out of old-fashioned cone drivers and dome tweeters in cabinets with the proper interior and exterior qualities, along with the proper space for them to do their work.

With the spotlight shining elsewhere, conventional speakers have had to perform that much better, and become that much more inexpensive, to still get noticed—and the speaker buyer who still favors the traditional approach clearly benefits from this. The new Silver RS speakers from Monitor are the perfect case in point, as they enter the scene at price points that are being bombarded by ever-smaller and more aesthetically driven competition. It seems obvious to me that the top priority with the Silver RS line is sound performance, although they happen to be pleasing to the eye, as well. They may not dazzle anybody who has a preference for outlandish or rebellious appearance—but appearance isn't what speakers are supposed to be about.

I went to work on a 5.1-channel Silver RS system made up of RS 6s in front, an RS LCR in the center (which, as the name suggests, can also be used vertically for left/right applications), two RS FX surrounds, and an RS W12 subwoofer. The 2.5-way RS 6 and RS LCR each put two of Monitor's highly regarded, 6-inch C-CAM drivers into play, with one reproducing only bass and the other functioning as a midbass unit. The C-CAM drivers, which are designed and built by Monitor, use a ceramic coating applied to an aluminum/magnesium core that allows them to exploit the benefits of both substances (e.g., the rigidity of ceramics and the strength of metal). The tweeters are also C-CAM drivers that are single 1-inch domes on both the RS 6 and RS LCR. Well-placed internal bracing at critical resonance modes keeps the cabinet performance purer, and reflex ports at the front and rear of both the RS 6 and the RS LCR help reduce internal pressure that can lead to low-frequency compression. Two sets of good-quality, five-way binding posts allow for biamping or biwiring.

The RS FX uses a 6-inch C-CAM driver on its front baffle that always operates in phase and a 1-inch C-CAM dome tweeter on each of its side baffles that you can switch between dipolar and bipolar output. A low-slope, linear phase crossover helps deliver 180-degree dispersion characteristics. The RS FX's relatively lightweight and manageable dimensions, as well as the attached keyhole brackets, make for easy wall mounting.

Fairly manageable dimensions characterize the RS W12 subwoofer, as well. It is on the heavy side for its size, though, thanks to a healthy 500 rated watts of internal power, in addition to the 12-inch C-CAM woofer and the impressive motor assembly behind it. The back panel offers an adjustable crossover control (40 to 120 hertz) and a crossover-bypass switch. There's also a phase switch (0 or 180 degrees) and line-level inputs and outputs (RCA). The front panel supplies gain control and two EQ settings—one flat and the other with a 4-decibel boost.

Strong midpriced speakers deserve strong midpriced backing, so I set up the RS Silvers with a Parasound C2 pre/pro, a Sunfire Cinema Grand amplifier, and a Marantz DV8300 universal player. I set the front speakers a couple of feet out from the side and rear walls, with a slight toe-in. I then set the center channel on top of the TV, which conveniently put its drivers right around ear level in the seated position. I placed the rear speakers on the side walls, about 2 feet above ear level and approximately 120 degrees from the listening position. Finally, I placed the sub halfway along the side wall, firing to the rear.

The first thing to grab me about the RS 6s with two-channel material was their prodigious bass. It was punchy, full-bodied, and deep, but never bloated or forced. Granted, these aren't exactly bookshelf speakers, but they aren't room-dominating towers, either. Call them mini towers if you must—and be impressed that this much clean, potent bass can come from two 6-inch drivers in a cabinet this manageably sized. They knocked out the driving bass line of Sara K.'s rendition of "Brick House" (Super Audio Collection Vol. 2, Chesky) with a clear sense of authority and composure. Pink Floyd's "Another Brick in the Wall" from the second Burmester collection tested both ends of the frequency range. The bass remained impressive, and the upper frequencies avoided almost all of the trappings that characterize inferior metal tweeters. They maintained their clarity and immediacy without becoming harsh or fatiguing.

Good-quality speakers usually live or die in the midrange, and, after I'd listened to the RS 6s' midrange performance, especially with high-resolution material, I found myself doing a double-take at their price. Vocals were entirely natural and full bodied, and midrange-dwelling instruments, which includes most instruments, had a presence and dimensionality that you don't often get from speakers at this price level. Whether it was blues or bluegrass, jazz or rock 'n' roll, the Silver RSs responded with a blend of effortlessness and enthusiasm that was altogether engaging. Their treatment of Ralph and Carter Stanley's magical pipes from "Angel Band" (O Brother, Where Art Thou? soundtrack, Lost Highway Records) was especially memorable, with an accuracy that was every bit the equal to much more expensive speakers.

The Silver RSs' impressive musicality continued with movie soundtracks. They developed stage dimensions that belied their physical dimensions and gave music-heavy soundtracks like Crouching Tiger, Hidden Dragon, The Blues Brothers, and Almost Famous ample space to work with. To the eye, the RS LCR is probably the classic definition of a medium-sized center channel. But, to the ear—and that's what really counts—it has the sound of a much bigger speaker, one that wouldn't fit as well as the RS LCR does atop a medium- or small-sized TV. Quality drivers, a quality cabinet, and a quality crossover design all contribute to the speaker's avoidance of virtually all traces of boxiness. It's highly successful at sorting out dialogue, music, and effects, as well, and resists being overwhelmed by even the densest center-channel tracks. Jake and Elwood's purposefully mundane banter in chapter 10 of The Blues Brothers had an easygoing sonic characteristic, even while police cars and a shopping mall were demolished all around them.

The RS W12 and RS FXs had their say during soundtrack demos, as well. As good as the bass was on the RS 6, the RS W12 enthusiastically took over the low-end rumble for soundtracks. Like the RS 6, The RS W12 carries a big punch in a relatively small package and does its work without resorting to boominess or monotonality. The C-CAM driver is also impressive in its 12-inch form, with a quickness and bite that lets large sonic events like explosions finish properly and then quickly reload for the next sortie. The RS FXs are agile, throwing surround effects around the room with little in the way of localization, especially in the dipole mode. Their compact size doesn't allow them to develop the largest surround field you've ever heard, but they provide more than you'd expect from their cabinet dimensions and more than enough to fill up the back of most regularly sized listening rooms.

There's no denying that speaker shopping at this price level is a daunting task these days, primarily due to the sheer number of available options. But, then again, the more options you have, the better chance you have of finding exactly what you want. Something like Monitor's Silver RSs would be a pretty good place to start. The speakers are well designed and well built, and they were clearly designed with audio performance as the top priority. It doesn't hurt that they are space friendly and manageable—and easy on the eyes, as well. They don't tout revolutionary technology or radical form; they just sound good—and that's my kind of speaker.

Highlights
• Big sound in a relatively small package
• Excellent build inside and out
