Revel Concerta2 M16
Bookshelf speaker (High Gloss White)
Our take on the Revel Concerta2 M16 by Crutchfield's Steve Kindig
A better look at the M16 tweeter's acoustic lens and waveguide (shown in High Gloss White)
Small but mighty
You just landed on one of the best-sounding bookshelf speakers available in the under-$1000/pair price range. The Concerta2 series is Revel's value line, but it shares much of the design and materials of Revel's costlier Performa3 models. Matched with Revel's optional speaker stand, the M16 can bring you closer to your favorite music.
A speaker that lets the music speak for itself
The sound qualities you expect from Revel — clarity, accuracy, and uncompressed dynamics — are all right here. The M16's big sound belies its small size. And it can pull off a convincing disappearing act — it's difficult to pinpoint where the sound is coming from. This seamless, spacious soundstage gives a realistic sense of presence to both music and movie soundtracks.
Custom-designed drivers reduce bad vibrations
Revel designs and builds every driver that goes into their speakers. The M16's 6-1/2" woofer uses an aluminum cone that's coated on both sides with a micro-ceramic composite compound. This stiffens the cone to help it move in a more piston-like fashion, and also reduces resonances that can color the sound.
The M16'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 match between the tweeter and the woofer just below it. The result is very smooth, consistent sound both on-axis and off-axis, creating a larger sweet spot.
An advanced cabinet forms a solid foundation
The Concerta2 cabinet isn't quite as sophisticated as those on Revel's pricier Performa3 models, but its design and execution are more advanced than you typically find in 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 M16's sleek looks.
The M16'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.
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.
Build a complete Revel system
A pair of M16s can fill your room with vivid stereo sound. If you're interested in a voice-matched surround sound system, check out these other models from Revel's Concerta2 series:

Two-Way Bookshelf Loudspeaker: The Revel by Harman Concerta2 M16 two-way bookshelf loudspeaker 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 M16 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.
- 6.5" Anodized Aluminum Woofer: The M16 two-way bookshelf loudspeaker also houses a 6.5" anodized aluminum cone woofer with rubber surround which offers ideal piston-like performance, eliminating resonances that would otherwise color the sound. By repositioning the voice coil in the woofer, Revel engineers discovered they could improve the symmetry of the woofer displacement and thereby lower distortion. They also adjusted the woofer's spider progression to greatly improve the woofer's linearity, and as a result - lowered distortion.
High Order Crossover Network: The Concerta2 M16's high order crossover network features carefully-selected components that contribute to its great performance. The high order crossover network blends the tweeter and woofer 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 M16 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 M16 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 M16 bookshelf 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 optional M16 STAND pedestal stand (sold separately - see accessories tab) is available for the M16 that place the speaker at the proper height for seated listeners. There are four 1/4"-20 threaded inserts on the bottom of M16 for securing the speaker to the M16 STAND. The speaker does not offer any rear-panel threaded inserts, keyhole slots, or integrated bracket for wall mounting. For best stereo image and performance, follow these guidelines -
- Place the speaker so the tweeter is aligned with a seated listener's ears, approximately 36" (91cm) above the floor.
- 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.
