Klipsch's R-2800-CSM-II in-ceiling speaker demonstrates that big sound need not equal bulky, room-filling speakers. It sports a 8" polypropylene woofer for tight, full-sounding bass, plus two 3/4" silk dome tweeters for faithful reproduction of both left and right channels of a stereo signal. With an overall width of about 11" this speaker isn't exactly small, but its stereo input design lets music lovers fully enjoy their tunes in rooms where a conventional left and right speaker pair wouldn't be convenient to install.

Keeping a low profile

The '2800-CSM-II- stays comes with a SlimTrim™ grille that minimizes the impact on your décor. The visible frame size is reduced by 90% and grille depth is reduced by 80% over previous designs, for a nearly flush finish that blends in beautifully. The paintable, aluminum, magnetic grille attaches securely with ease to virtually eliminate resonant distortion.

An optional in-ceiling bracket is recommended for installing the R-2800-CSM-II in new construction (or a room that's undergoing major renovation).

    Mounting Options


    Stereo Input: This in-ceiling speaker can be used to play stereo from a single speaker, convenient in a location when there is not room for a pair of speakers.  Separate left and right channel inputs provide stereo signal in a single speaker application. The speaker has two pair of spring clips that can accept pin connectors or bare wire up to 12-gauge wire.

    High Efficiency: The high-efficiency design of the Klipsch in-ceiling speakers allows you to get much more output than most in-wall and in-ceiling speakers. Due to the long speaker wire runs that are common in whole-house audio systems, the power coming from the amplifier is significantly reduced by the time it reaches the speakers. The 94dB efficiency of this speaker means it will play much louder at low power than other less-efficient speakers.

    Drivers: The R-2800-CSM II uses two high-quality 0.75" silk dome tweeters, combined with a dual voice coil 8" polypropylene woofer in a 2-way design.

    • Dual Tweeters: The low-resonance, 0.75" Silk Dome tweeters reproduce high frequencies from both channels of a stereo source with ambience
    • Dual Voice Coil Woofer: The dense, yet lightweight, 8" polypropylene woofer utilizes one voice coil for each channel of a stereo source in order that all low frequency information from both channels is heard.

    ABS Basket/Frame: The R-2800-CSM II has a sturdy ABS basket and frame. The frame can be painted to match any decor.

    SlimTrim Magnetic Grille: With an all new grille, the visible frame size is reduced by 90% and grille depth is reduced by 80% over the previous design, for a more edge-to-edge consistent look that blends in with the wall more attractively. The new aluminum, paintable, magnetic grille attaches tightly and securely with ease to virtually eliminate resonant distortion.

    Power Specifications Note: The manufacturer has specified the maximum power handling of this speaker as 50 watts RMS (200 W Peak). Klipsch has also published a recommended amplifier power specification as 100 watts.

    Mounting Options

    Installation: The speaker can be installed in new or existing construction. It requires a cutout diameter of 9.8125". For new construction, purchase of the IK-800-C installation kit (714IK800C, sold separately) is highly recommended. For existing construction, the speaker should be installed in drywall at least 3/8" thick. It can also be installed in a drop ceiling (2' x 2' or 2' x 4' ceiling tiles only). In both cases, to maximize the acoustic performance of the in-ceiling speakers, Klipsch recommends you replace the original mounting panel with 1/2" or 3/4" plywood or MDF. A cardboard template is included to assist you in making the cutout.
