Our take on the Revel C763 by Crutchfield's Kramer Crane
Elite overhead sound from Revel
Revel's C763 is the best 6-1/2" speaker in the company's in-ceiling lineup. You get outstanding Revel performance that can be tailored to your room. Its 1" aluminum dome tweeter has a three-position output level switch, which lets you cut or boost the high frequencies. And a boundary compensation switch lets you adjust low-frequency output when the speaker is placed near a wall, to prevent potential boominess.
The Revel C763 in-ceiling speaker offers both tweeter and woofer adjustments to tailor its sound to your room.
High-quality design for long-term performance
The C763 has a few other notable design highlights. Its tweeter waveguide helps provide great sound for listeners directly under the speaker, as well as those positioned off to the side. Its high-order crossover network allows the woofer and tweeter to blend together seamlessly. And high-quality push-post input terminals provide a solid connection with your speaker wire.
The C763 even comes with square and round grilles to match your décor. A lifetime warranty ensures excellent long-term performance.
Ideal for music and movies
The C763 is a great choice for a high-end in-ceiling stereo system. Or use this speaker as an overhead effects channel as part of a Revel home theater system. You'll enjoy rich, full-bodied sound with all of your favorite content.

Two-Way In-Ceiling Speaker: The Revel by Harman C 763 in-ceiling speaker utilizes a two-way driver design. It features a 1" aluminum dome swiveling high-output tweeter with an integrated wave guide that provides optimized response both on and off axis. It also houses a 6.5" micro-ceramic composite (MCC) woofer with rubber surround that provides high output with low distortion. A high-order crossover network delivers seamless blending between the tweeter and woofer, as well as accurate timbre reproduction.
Tweeter Level Control: A 3-position tweeter level control lets you adjust for optimum high-frequency response in a variety of acoustical environments, or for using the speakers without grilles. The tweeter level control is located on the front baffle and hidden behind the grille. Choose between 3 settings -
- Increased High Frequency Output (+): Use this setting if the room has many features that absorb high-frequency sound energy - such as thick carpeting, drapes, and fabric-covered furniture.
- Normal High Frequency Output (0): Use this setting for most installation.
- Decreased High Frequency Output (-): Use this setting if the room has many features that reflect high-frequency sound energy - such as large uncovered windows, bare tile floors and large expanses of bare walls, or if the speakers are used without grilles.
Boundary Compensation Control: The Boundary Compensation control reduces the speaker's bass output level to compensate for the greater reflection of bass energy when the speaker is placed near a wall. When possible, avoid mounting the speaker within 2' of a wall. If such placement is unavoidable, set the Boundary Compensation control to the "On" position. The Boundary Compensation control is located on the front baffle and hidden behind the grille.
Spring-Post Terminals: The C 763 in-ceiling loudspeaker 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-ceiling speaker.
- 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.
Magnetic Grille (Round & Square): The C763 in-ceiling loudspeaker comes with a round and square metal mesh grille (choose the one that looks best in your ceiling). Powerful magnets in the speaker frame securely hold the grilles in place. The grille covers the entire outer frame of the speaker and is extremely low-profile (sits out only 0.25" from the ceiling). The included grilles can be painted to match your room's décor.
Applications: The C 763 in-ceiling speaker can be used in distributed audio, two-channel stereo, and home theater applications.
- Distributed Audio: Since distributed sound is general sound throughout an area, place the loudspeakers as uniformly as possible for even sound coverage throughout the area. Place the left and right loudspeakers roughly the same distance from the primary listener locations. To avoid "hot spots" where the sound is too loud, plan to use more loudspeakers, with each set to play at a lower volume.
- Two-Channel Stereo: Place the left and right loudspeakers the same distance from the primary listening area (or as close to the same distance as possible). The distance from each speaker to its nearest side wall should also be the as close to the same distance as possible. Ideally, the distance between the left and right loudspeakers should be slightly less than their distance from the primary listening area.
- Home Theater: The front left, center and front right loudspeakers
should be centered relative to the video display; and should be closer to
the video display than to the main listening area. The front left and front
right loudspeakers should be relatively close to the sides of the video
display, while he center loudspeaker should be aligned with the center of
the video display. The surround-channel loudspeakers should be as far from
the main listening area as possible but at least 2' from side and rear
- In a 5.1-channel system, the surround left and surround right loudspeakers should be located directly to the sides of, or up to 10°behind, the main listening area
- In a 7.1-channel system, the surround left and surround right loudspeakers should be located directly to the sides of, or up to 10° behind, the main listening area; while the surround back left and surround back right loudspeakers should be equidistant from the primary listening area and generally as far from it as possible but at least 2' from the side and rear walls.
Mounting Options: The C 763 is designed to mount in a 0.5"-2" thick ceiling. Make sure the drywall, plywood or other ceiling material capable of withstanding the weight (2.4 lbs) of the speaker. Use the included template to assist you with marking the cutout opening (8" diameter) for the speaker. Be sure there is at least 4.9375" of mounting depth behind the wall, and allow at least 3/4" between the edge of the supplied installation template and any rafters or other obstructions behind the wall - so the speaker's locking mechanism will have room to engage fully. Four "dog-ear" clamps will secure the speaker in your ceiling.
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.
