Revel Concerta2 F36
Floor-standing speaker (High Gloss White)
Our take on the Revel Concerta2 F36 by Crutchfield's Steve Kindig
Revel has managed to remain one of the best-kept secrets in high-performance audio, even though they've been building award-winning speakers for over 20 years. The Concerta2 F36 looks and sounds a lot more expensive than it is. In fact, its detailed, dynamic sound bears a strong family resemblance to Revel's pricier Performa3 models.
Custom drivers produce seamless sound from top to bottom
The F36 is a full-range "2.5-way" speaker: the three 6-1/2" aluminum cone drivers are identical but they don't all cover the same frequency range. The topmost driver handles the upper midrange, and because it's physically close to the tweeter, you get a seamless blend of mid- and high-frequency sounds, for improved imaging. The other two woofers cover the lower midrange and bass frequencies.
All three aluminum cones are anodized on both sides with a patented micro-ceramic composite compound to reduce resonances. Resonances can color a speaker's sound, and Revel uses advanced testing like laser interferometry to root out those kinds of sonic imperfections. Revel designs and builds every driver that goes into their speakers.
The F36's 1" aluminum dome tweeter sits in Revel's concave Acoustic Lens waveguide, which increases the tweeter's dispersion at higher frequencies, and also helps create a more seamless sonic match between the tweeter and the midrange driver just below it. The result is very smooth, consistent sound both on-axis and off-axis, creating a larger sweet spot.
Careful cabinet design pays off
The Concerta2 series cabinet isn't quite as sophisticated as those on Revel's pricier Performa3 models, but its design and execution are more advanced than is typical for this price range. The curved side walls create a stiff enclosure that forms a solid foundation for Revel's custom-designed drivers, as well as contributing to the F36's sleek looks.
The F36's grille attaches magnetically, so there's no ugly hardware on the front baffle of the speaker if you decide to leave the grille off. As far as the bottom of the speaker, you can take your choice between the included sets of large rubber feet and spikes.
Tested by instrument and by ear
Revel's world-class speaker design and testing facility features an anechoic chamber and the latest high-tech measurement gear. But some of their most critical test instruments are the ears of their trained listening panel. When working on a new design, Revel's engineers set up a series of controlled auditions comparing their design to several competing speakers.
Speakers under comparison sit on a rotating platform, and each model is moved into the identical position by a computer-controlled belt drive system. An acoustically transparent screen hides the speakers from the listeners to avoid visual bias. These double-blind listening tests provide an essential reality check, and help the engineers correlate measurements with what listeners actually hear and prefer.

2.5-Way Floorstanding Loudspeaker: The Revel by Harman Concerta2 F36 is a 2.5-way floorstanding loudspeaker that delivers an impressive combination of wide frequency range, uncompressed dynamic range, and low distortion across the entire audible spectrum. Revel engineers utilize state-of-the-art computer modeling tools during driver design to optimize everything that affects performance. Laser-based analysis of the resulting prototypes confirms ideal symmetry, which results in lowered distortion and cleaner sound quality.
- 1" Aluminum Dome Tweeter w/ Acoustic Lens Waveguide: The Concerta2 F36 is equipped with a 1" aluminum dome tweeter with an Acoustic Lens Waveguide. This patented 4th generation Acoustic Lens Waveguide design improves tweeter to woofer blend and significantly improves off-axis response for consistent performance over a wide listening area. Unlike previous waveguide designs, this new Acoustic Lens Waveguide design actually increases dispersion at the highest frequencies, when compared to conventional tweeters. The result is a noticeably improved sense of air and detail, contributing to greater musical enjoyment.
- Triple 6.5" Anodized Aluminum Woofers: The F36 2.5-way floorstanding loudspeaker also houses three 6.5" anodized aluminum cone woofers with rubber surrounds (one woofer acts as a midrange driver, while the other two act as bass woofers). These anodized aluminum cone woofers offer ideal piston-like performance, eliminating resonances that would otherwise color the sound. By repositioning the voice coil in the woofers, Revel engineers discovered they could improve the symmetry of the woofer displacement and thereby lower distortion. They also adjusted the woofers' spider progression to greatly improve the woofer's linearity, and as a result - lowered distortion.
High Order Crossover Network: The Concerta2 F36's high order crossover network features carefully-selected components that contribute to its great performance. The high order crossover network blends the tweeter and woofers together for a smooth, natural sound. This advanced crossover network also dramatically reduces distortion and dynamic compression for clear sound that maintains the same quality over a very wide dynamic range. In addition, this precision crossover network optimizes the speaker's timbral accuracy, enhancing musical enjoyment for listeners who are anywhere in the room, not only those seated on-axis to the loudspeakers.
Constant Pressure Gradient (CPG) Port Technology: The Concerta2 F36 uses a patented Constant Pressure Gradient (CPG) technology in the port design (it has a rear-firing bass port). This new port is designed such that the inner wall of the port is contoured, allowing the change in pressure along the axis of the port from inlet to outlet duct to be kept substantially constant. This design reduces the compression, or change in sound at different volumes that result from other port designs, resulting in optimized output capability with lower distortion.
Rigid, Curved Enclosure: The Concerta2 F36 speaker enclosure is not only beautiful, but also rigid, with curved 1"-thick side walls and extensive internal bracing that result in a strong and inert enclosure. This ensures that the enclosure does not contribute coloration to the sound. A cloth magnetic grille eliminates unattractive hardware on the baffle and also minimizes diffraction and veiling. The speaker enclosure is available in a high gloss black or white finish.
Binding Post Terminals: The F36 floorstanding loudspeaker features gold-plated binding-posts that provide secure connection for speaker cables terminated with banana plugs (single or dual), spade-lugs, pin-connectors, or bare wire (up to 10AWG). You will need to remove the binding post's rubber inserts in order to use banana plugs.
Mounting & Placement Options: The F36 loudspeaker is equipped with four integrated rubber feet for optimal stability on hardwood, laminate, vinyl, or tile flooring. If you are placing the speaker on carpet, use the four included spike feet which screw into the rubber feet on the bottom of the loudspeaker. The speaker measures 44.3125" tall using only the integrated rubber feet. The speaker measures 44.75" tall with the spike feet installed. For best stereo image and performance, follow these guidelines -
- Place the loudspeakers so that they are both the same distance from the primary listening position and so they are both the same distance from the side walls.
- Angle the loudspeakers almost directly toward the primary listening position. If you wish to widen the stereo soundstage you can reduce the toe-in angle, even to the point at which the loudspeakers are pointing straight forward.
- Moving the loudspeakers farther from the front and side listening room walls will improve stereo imaging and the sense of spaciousness in the listening space.
- Moving the loudspeakers closer to the corners or walls of the listening room will increase bass response.
Note: Placing minimal acoustic treatment materials at the room's primary reflection points will reduce sonic degradations. Ideally, acoustic absorbers should be placed at the first reflection points on the front and side walls and either acoustic absorbers or diffusers should be placed at the first reflection points on the rear wall. Check out the Accessories Tab for acoustic panels & treatments (sold separately).
Position-Independent, Double-Blind Listening Tests: Every Revel by Harman loudspeaker is compared head-to-head with competitors' models in a position-independent, double-blind listening facility. True research-quality processes assure the validity of the listening tests, which employ the latest psychoacoustic research.
