Ready, aim, music!

The '5650-C-II's tweeter gives you 100-degree dispersion, and it swivels, so you can aim the sound precisely where you need it to go. You can even rotate the 6-1/2" woofer a full 360 degrees and tilt it up to 15 degrees in any direction. This flexibility gives you full, detailed sound no matter where you place the speaker. Plus, tweeter and mid-bass level switches let you adjust the sound to suit your personal taste and room's acoustics.

Horn technology for room-filling sound

Because high-frequency sounds are more directional than bass frequencies, it's especially important to target them right toward your ears. Klipsch places their titanium tweeter inside a flared opening, known as a "horn." This design brings out details in everything you listen to, while reducing reflections that can color the sound.

Keeping a low profile

The CDT-5650-C II stays inconspicuous with its SlimTrim™ grille. 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 CDT-5650-C-II in new construction.

    Good Surrounds in an open plan

    Tyler from Panama City, FL on 1/16/2019

    Crutchfield Customer Review (What's this?)

    Using these as surrounds in a 5.1 setup in an open floor plan. Speakers sound clear and crisp. Haven't really pushed them since they are only surrounds but they complement the rest of my system quite well. Installation took < 1 hour once the locations of the holes were measured and speaker wire run. The only ding was the price but I wanted something that would complement my existing Klipsch fronts/sub.

    Pros: Great Sound, Easy installation, attractive slim cover/grill

    Cons: price

    Pros: Easy install and excellent grill cover. Moveable tweeter.

    Cons: Tad pricey

    Perfect Choice for Ceiling Audio

    Terry from Grand Blanc, MI on 2/25/2018

    Crutchfield Customer Review (What's this?)

    I am very pleased with these speakers. I added them to my home theater to create the Dolby Atmos and DTS-X sound. They were easy to install. The magnetic grill comes colored white which was perfect for my ceiling tiles. They can be painted. When I ran the Audyssey® Setup function on my Marantz SR7012 everything worked out splendidly. They work well with my Bose Acoustimass 10 surround. I may add two more in the future. I definitely recommend this speaker for above listener/viewer sound.

    Pros: 1.Great sound! 2.Easy installation! 3.They look awesome!

    Cons: None!

    Crutchfield Customer Review (What's this?)

    They match up well as surrounds with my other Klipsch speakers. Great clarity.



    Perfect surrounds for my HT setup.

    Gary from East Amherst, NY on 10/5/2016

    Crutchfield Customer Review (What's this?)

    Used these as rear surrounds to match my Klipsch Atmos towers and center speakers. Love it all!!!

    Pros: Matches my Klipsch towers and centers (timbre).

    Cons: none

    Great speakers

    Arnie from Texas on 1/11/2016

    Crutchfield Customer Review (What's this?)

    I bought two pair of these. One in my living room for rear surround and one for my office. First off the installation was super simple. There was a nice cardboard template to mark the hole in the ceiling. Connecting the wire was simple and secure. But the best part was mounting it. A 1/4 turn of four screws and it was secure to let go with both hands, then it was just a matter of tightening them. I've never really don't something like this before, but I installed both pairs, including running wire and doing the drops (and cleanup) in about 6 hours. So far I'm very happy, but I've only had them up for two days.

    Pros: Ease of installation.

    Using these as surround speakers with reference series bookshelf rb51 and center rc52 channel. Speakers are a great sound match, very loud when pushed. Install was easy with template.

    Pros: Great sound, match my existing setup. Crutchfield is always great to work with

    Cons: Pricey

    Mounting Options


    Controlled Dispersion Technology (CDT): The Klipsch CDT-5650-C II in-ceiling speaker features a patent-pending gimbal mechanism, known as Controlled Dispersion Technology (CDT). The tweeter and woofer are independently adjustable, allowing both the high and low frequencies to be directed toward the listening area.

    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.

    2-Way Driver Design: The Klipsch CDT-5650-C II uses a high-quality 1" titanium dome compression driver (tweeter) mated to an exclusive Tractrix Horn, combined with a 6.5" Cerametallic woofer in a 2-way design.

    • Tweeter: The 1" Titanium dome compression tweeter is mated to a swiveling 100° Tractrix Horn. The swiveling horn design dramatically increases efficiency by enabling the speaker to produce more output using less energy. The horn-loaded tweeter allows you to point the sound to a specific location, and has more controlled directivity than a conventional dome tweeter. The addition of a Linear Travel Suspension to the tweeter increases high frequency detail and smoothness
    • Woofer: The 6.5" copper-colored, machine-spun Cerametallic woofer can rotate a full 360°, and then shift 15° in any direction. The solid Aluminum diaphragm, anodized to add stiffness and provide perfect damping, has a new hi-tech look that also delivers increased rigidity for even tighter, more defined bass. The new integrated dust cap further strengthens the cone and helps ventilate the voice coil for increased driver durability.

    Speaker Terminals: The speaker has a pair of spring-loaded binding posts that can accept up to 12-gauge wire, as well as pin connectors and single banana plugs.

    Tweeter/Mid-bass Attenuation Switches: If the speaker is installed in an acoustically bright room, such as a bathroom or a kitchen, you can attenuate the tweeter by -3dB, using the Tweeter Attenuation Switch. If the speaker is located in a corner and produces too much bass, you should adjust the Mid-bass level switch (-3dB). Both switches are located on the front of the speaker.

    ABS Basket/Frame: The CDT-5650-C 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 8.1875". For new construction, purchase of the IK-650-C installation kit (714IK650C, 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.

    The rest of my speakers are Klipsch. [ PHILIP  Jun 22, 2018 ]
    I needed an in-ceiling speaker for my Auro-3D system, and this was a nice fit for the rest of my Klipsch Reference speakers. [ MICHAEL  Jul 06, 2017 ]
    I have had these in the past in my prior house. They are great speakers (sound great, and are out of sight) and since we are finishing our basement in our new house I figured I would go with them again. [ David  Feb 24, 2017 ]
    I wanted a surround speaker but had limited wall and floor space and desired a cleaner look in my room. [ Dan  Oct 09, 2016 ]
    I have Klipsch front speakers and will use these for surrounds [ ransak  Sep 21, 2016 ]
    referral to speakers from a friend [ David  Feb 17, 2016 ]

    3 questions already asked

    If you are referring to the rear of the cone and the driver, yes. Technically, yes you can however that is not advised. If at all possible, try to move the insulation out of the way so it won't be on the driver. Personally, I used and recommend the ME-650-C. That's a metal enclosure that is insulated, but leaves room above the driver for proper operation and sound production. [ Ronald  Oct 11, 2018 ]
    That's a good question. I guess it depends on where you install the speaker...I installed mine in the ceiling of the upstairs, so the insulation would ultimately allow moisture in during the humid summer months. So I used speaker baffles to protect the speaker from dust and as a moisture barrier. I used 10" XTC baffles (Item # 237XT10) and sprayed Great Stuff for windows (the blue can) between the ceiling (plywood support and baffle) to form a seal and seems to have worked very well. Also, the speaker has some weight, so since I'm doing a full remodel I placed 3/8" plywood between the rafters as a support for the speaker then cut the drywall to fit over the plywood...the speaker sits on the drywall and the back clips secures the speaker against the plywood, it worked well. [ PHILIP  Oct 11, 2018 ]
    Yes, it is all sealed in back. Awesome product! [ Dzmitry  Oct 11, 2018 ]
    For a Dolby Atmos system, it's generally recommended that *only* the Atmos speakers go in your ceiling; so while the Klipsch CDT-5650 would be a great choice for overhead/Atmos speakers, you may want to consider a different option for the surround speakers in your setup. For more assistance, or to discuss further, please contact an Advisor directly by phone (888.955.6000) or online chat. Thanks! [ Larry  Jun 15, 2018 ]  Staff
    If you want all 5 of the primary channels (front left, center, front right, rear right, rear left) in-ceiling, sure, you can use the CDT-5650-C II for all of them. You'll also want to add a powered subwoofer for the deepest bass effects (LFE). I hope that helps My Bio: [ Ryan  Dec 27, 2017 ]  Staff
