Our take on the Klipsch CDT-5650-C II by Crutchfield's Marshall Chase
Treat yourself to top-notch sound with a speaker that blends seamlessly into your home's décor. The Klipsch® CDT-5650-C-II installs in your ceiling, so it won't take up one inch of floor space. And its high-tech design and solid construction make it a great choice for movie and music lovers alike. You can use multiple CDT-3800-C IIs for surround sound in an all-Klipsch home theater, or install them in pairs for stereo listening with your multi-room audio system. Either way, you'll enjoy crisp, clear Klipsch sound without the clutter of conventional speakers.
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.

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.
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.

Why did you buy this?
Great reviews, nice appearance for ceiling in new kitchen [ Tom Aug 27, 2018 ]
Quality! [ David Aug 22, 2018 ]
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 ]
1 answer I am wanting to use 6 of these in ceiling speakers 4 for Dolby Atmos and 2 for left and right surround sound. First question, what is the best speaker placement for this arrangement. Room size is 18' x 24' viewing is on the shorter dimension roughly 16' to projector screen. Second question, I have blown in insulation in the ceiling, do I need to protect the back of the speakers? If so, what size box should I build to prevent insulation from get inside and still allow proper air flow? [ T Jun 13, 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: https://www.crutchfield.com/bio/Ryan [ Ryan Dec 27, 2017 ] Staff
