Overview

Our take on the Revel B28W

I love my home theater's subwoofer. It delivers deep, hard-hitting bass that makes watching movies very satisfying. But that bass comes at a cost — a valuable chunk of living room floor space. A more discreet solution? The Revel B28W in-wall subwoofer.

Room-filling bass from an in-wall subwoofer

I love my home theater's subwoofer. It delivers deep, hard-hitting bass that makes watching movies very satisfying. But that bass comes at a cost — a valuable chunk of living room floor space. A more discreet solution? The Revel B28W in-wall subwoofer.

This hideaway sub offers high-quality bass without taking up any floor space, making it an excellent complement to a Revel in-wall or in-ceiling stereo or home theater system.

Be sure to use matching Revel amplification

The B28W requires Revel's matching SA1000 subwoofer amplifier (sold separately), which delivers a mighty 350 watts of power, in order to reach its performance potential. This amp goes on your equipment rack along with your home theater receiver and other A/V gear.

If you have a large room, or want more evenly distributed bass, install two B28W in-wall subwoofers and drive them both from a single SA1000 amp. Running at four ohms, the SA1000 delivers 350 watts to each sub.

Revel B28W in-wall subwoofer

Revel's B28W in-wall subwoofer has a built-in back-box, which keeps dust and dirt out while providing a high-quality sonic enclosure for the subwoofer.

Ideal for new or existing construction

The B28W features two high-performance 8" woofers that are optimized to perform inside a wall. It's designed to fit between standard 2" x 4" studs that are 16" on-center, making it an excellent choice for both new and existing construction.

Built-in back box helps produce high-quality bass

Excellent performance is due in part to this sub's carefully designed sealed enclosure. You get consistently focused, powerful bass no matter what kind of space is behind it in your wall. It also keeps dust and dirt out.

Features

Compatibility: This Revel by Harman B28W in-wall subwoofer is specifically designed to be used in conjunction with Revel's SA1000 subwoofer amplifier (sold separately). The B28W in-wall subwoofer is optimized to offer the best dynamics and frequency response with use of the SA1000 amplifier, which is specially engineered to drive the signature reactive load impedance of the B28W.

  • The SA1000 single channel, rack-mount amplifier has two outputs in parallel, so you can power one B28W in-wall sub with 350W RMS (750W Peak) @ 8-ohm.
  • When a second B28W in-wall subwoofer is connected to the second output of the SA1000 amplifier, the total output power increases to 700W RMS (1500W Peak) @ 4-ohm; 350W RMS (750W Peak) to each sub.
Note: The SA1000's EQ switch position "Type-2" and headroom management have been specifically designed for the B28W In-wall subwoofer. Use of the B28W with any other amplifier could lead to damage of the subwoofer and/or the amplifier.

Dual 8" Woofers: The Revel B28W features two high-performance 8" low-profile, long-throw, Klippel-optimized, polymer-coated aluminum cone woofers with rubber surrounds, which allow it to provide high-quality, high-performance low-frequency bass output.

Spring-Post Terminals: The B28W in-wall subwoofer is equipped with a set of spring-post terminals that will accept speaker cable terminated with banana plugs (single or dual) and bare wire (up to 10AWG). Use high-quality speaker wire to obtain the best performance from the Revel in-wall subwoofer.

  • For wire lengths of less than 50', use at least 16AWG speaker wire.
  • For wire lengths of 50' to 100', use at least 12AWG speaker wire.
  • For wire lengths of greater than 100' use at least 10AWG speaker wire.
Note: The B28W is designed for the terminals to point up as it sits in the wall

Zero-Bezel Grille: The zero-bezel grille provides an unobtrusive look that allows the in-wall sub to blend in seamlessly with its surroundings. The zero-bezel design enables the in-wall subwoofer to become virtually invisible within the room. The ultra-thin design attaches magnetically and completely covers the in-wall subwoofer. The grille is also paintable.

In-Wall Installation: This self-contained, in-wall subwoofer with integrated back-box allows for easy retrofit installation application. The subwoofer's design allows for a very unobtrusive, clean look when installed in your home with minimal visual impact. The B28W will require a 14.5" (w) x 23.5" (h) cutout with a mounting depth of 4.0". A combination of "dog-ear" clamps and mounting screws secure the B28W in the wall.

Placement Options: Positioning the B28W in-wall subwoofer as recommended will provide the most natural soundstage and imaging from your loudspeaker system.

  • It is recommended that you install your B28W in-wall subwoofer along the same wall as the front loudspeakers.
  • The B28W subwoofer is not video-shielded and should not be placed near a video display affected by magnetic fields.
  • Installing the B28W near a corner will tend to maximize low-frequency output. Be cautious when installing in a corner, to avoid a "boomy" sound.
  • Also, take into consideration any unusual features of the room, such as an alcove, which may tend to create a localized node that may affect bass response in that area of the room.

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.
