Ready, aim, music!

The CDT-5800-C II's tweeter provides wide dispersion for consistent sound, and it swivels, so you can aim the sound precisely where you need it to go. You can even rotate the 8" 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 your 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-5800-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-5800-C II in new construction.

    Great modification to an already great system

    Tom from Bentonville, AR on 9/11/2018

    Crutchfield Customer Review (What's this?)

    I have 9 of these speakers, all ordered from Crutchfield. I use 5 in a living room as part of a simple 5.1 surround system for TV and casual music listening. I also use 4 in a separate, full blown, professionally done home theater room as my in ceiling Dolby Atmos channels. The performance of the speakers in the living room is excellent for in ceiling speakers. I am totally pleased with their performance. In the theater room, when using these as Atmos channels, I am really, really impressed. Performance for this application is awesome. I was somewhat doubtful that these would improve my 7.2 system very much. But I thought I would try it. I was wrong. It made a huge difference. The only reason I give 4 instead of 5 starts is because upon receipt of the speakers, I discovered that 3 of them had tweeter horns that had become detached and were hanging by the wires. Crutchfield offered to replace them when they were back in stock again. Instead of waiting, I reattached them and snapped the collar back in place that is intended to hold them in their intended location. I tested them and they worked fine after I did a little first aid.

    Pros: Audio quality Flexible aiming options Ease of installation

    Cons: Packaging could be improved. Assembly method should be able to withstand a little transportation shock without coming apart.

    Excellent sound



    Awesome sound for ATMOS!

    eric from Wilmington, DE on 3/16/2018

    Crutchfield Customer Review (What's this?)

    The speakers have been great for Dolby Atmos. The sound effects coming from these speakers matches the tone of the Klipsch 250 surrounds. The effect that is achieved with these speakers is worth the expense. It creates a completely new experience by putting you in the middle of the action. You are in a bubble of sound. It makes the movie experience much more entertaining and just plain fun. Puts a smile on my face. When I opened the box I could not get over the build quality.

    Pros: Build Quality Good match for other reference premiere line products. Woofer and tweeter can be directed towards listening position.

    Cons: none

    Excellent Speakers

    Pros: Ease of setup Sound

    Awesome sound and easy to install!!

    Carl L from Lake City, Fla on 5/25/2016

    Crutchfield Customer Review (What's this?)

    Crutchfield came through within three business days. Got 4 of these for in-ceiling Dolby Atmos setup. Really well built and designed. You can actually aim these toward your listening area. Went up easy with the locking arms. The covers just hold perfect. Excellent sound from my Rx-a3050. Just can only say WOW about them

    Pros: Go up easy. Sound great.

    Cons: Not a thing

    Great Speakers

    Joe C from Lancaster, PA on 2/3/2016

    Great addition to my home theater setup. I'm running these as my rear speakers in my basement and they get the job done perfectly. I installed them in the ceiling with the optional Speaker Box Enclosure, ME-800C. Unfortunately Crutchfield does not sell the enclosure, but I was able to find it online easily. I can't say how they perform as stand alone speakers, but I'm sure they are fine for that as well. I do occasionally play music through a multi channel stereo setting and they don't give me any issues.

    Pros: Easy Install, clean design, nice price point.

    Cons: None

    Excellent Surround and Overhead Speakers

    RichardH from California on 12/10/2015

    Crutchfield Customer Review (What's this?)

    Great sound, super easy to install, lay very flat against the ceiling making them practically invisible

    Pros: Excellent sound, movies come to life

    Cons: My ceiling is white, if it were colored, I would want to paint the grill and it wasn't clear from any of the instructions if that is possible

    Crutchfield Customer Review (What's this?)

    Pros: Great surround speaker, and looks very clean especially if you have your painter spray the grill.

    Cons: None

    Crutchfield Customer Review (What's this?)

    Great sounding speakers for adding music to another room or part of a system. The install was so simple I was surprised. 100% recommend.

    Pros: Great product. Clean, crisp sound.

    Cons: None.

    Great Sound

    Al from San Diego, CA on 12/30/2014

    Crutchfield Customer Review (What's this?)

    The speakers themselves are very easy to install and sound great. It was an awesome way to add surround sound to a space that wasn't configured for wall attachments or freestanding speakers. CAVEAT: If you do not have an attic for running wire and you haven't opened up your walls or ceiling before, I'd recommend you pay for a pro to install it -- time is money and a pro will save you time and frustration.

    Pros: Easy install; Look great; sound great; aimable

    Cons: For the speakers themselves - none. The con is that you have to run wire in the walls.

    Marksouth from Wichita Falls, TX on 11/7/2014

    Crutchfield Customer Review (What's this?)

    The speakers were very easy to install, and the magnetic grill covers are a great innovation. I really like the swivel woofer and tweeter on this speaker as well. Sound is great, and they can handle a lot of power.

    Pros: Easy install. Magnetic grill covers. Swivel woofer and tweeter.

    Cons: None


    DanW from Austin, TX on 5/24/2014

    Crutchfield Customer Review (What's this?)

    I bought these as front speakers to replace an old set of Bose 301s. They sound better than the bookshelf speakers hands down. The music quality is phenomenal and the tv/BD sound is awesome. I can't wait to get another set for the rear channel.

    Pros: Easy install, excellent sound

    Cons: Bass response is OK, although that is what a subwoofer is for and not why I purchased these speakers

    Pretty Nice Speakers

    Crutchfield customer from los angeles on 5/21/2014

    Crutchfield Customer Review (What's this?)

    I used two of these for a large room paired with a sub woofer and they filled the room quite nicely. Good speaker construction and the installation hardware seemed to work well. I like the idea of the built in tweeter and mid-bass level switches , however it did sound a bit muffled when tuned down. Great mids and highs and the adjustable directional tweeter adds a nice touch. Lows could use a bit more punch, I would recommend a sub woofer for stereo or surround applications.

    Pros: mids and highs, adjustable tweeter, installation hardware

    Cons: Could use a little more low-mid bass

    awesome speakers

    Pros: Awesome sound quality.

    Ceiling speakers for Sonos Amp

    Bill Y from Basking Ridge, NJ on 3/14/2013

    Crutchfield Customer Review (What's this?)

    When you read the product description of most high-end ceiling speakers, it seems many are intended for use as part as of a home theater surround sound; my interest was simply to have good sound playing from a Sonos Amp. The sound from the 5800's was absolutely clear but just didn't have enough bass for our liking. I would imagine these being the best choice if I were looking for rear surround speakers and wanted the clearest dialogue and high sounds while the sub and big front speakers carry the bass.

    Mounting Options


    Controlled Dispersion Technology (CDT): The Klipsch CDT-5800-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 95dB efficiency of this speaker means it will play much louder at low power than other less-efficient speakers.

    Drivers: The Klipsch CDT-5800-C II uses a high-quality 1" titanium dome compression driver (tweeter) mated to an exclusive Tractrix Horn, combined with an 8" Cerametallic woofer in a 2-way design.

    • Tweeter: There is a 1" titanium dome compression tweeter 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 pivoting tweeter can be angled up to approximately 20° in any direction (relative to the woofer).
    • Woofer: The 8" 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.

    Speaker Terminals: The speaker has a pair of gold-plated, 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-5800-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 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.

    10 questions already asked

    They sell a hanger kit which fit between the joists. No need to re-enforce at all. I did however double up on the speaker wire and soldered ends. system works great. Also put in wall speakers at same time. really nice system albeit expensive but great if you can do the work yourself [ TAM  Dec 04, 2017 ]
    No. The tabs that hold it in place allow for varying thicknesses and the instructions mention using 3/4" MDF/plywood if using it in a dropped ceiling. [ Curt  Dec 04, 2017 ]
    Yes. I did the same with a pair. No issue. Klipsch has a custom mounting box that I used with a second pair that I liked even more. [ Quintin  Dec 03, 2017 ]
    They are not recommended for use in "all weather" outdoor installations. [ Ryan  Mar 23, 2017 ]  Staff
    Sorry can't help. Put them in ceiling in house in California where temperature doesn't fluctuate much. [ THOMAS C  Mar 16, 2017 ]
    Yes. I used them with 4 ceiling speakers and it was a completely secure match/fit with no issues. [ Quintin  Jan 16, 2017 ]
    Yes. Did it in my new house. Easy installation. [ Douglas  Jan 16, 2017 ]
    Yes it will work. We used it with the CDT 2800 and the CDT 5800 shows the same speaker depth. [ ERIC  Jan 16, 2017 ]
    I wondered the same thing, and just painted the ceiling swiss coffee to match the speaker instead [ Richard  Aug 09, 2016 ]
    The woofer and tweeter can be aimed towards the listeners [ LENARD  Jul 03, 2016 ]
    The entire speaker rotates and the tweeter swivels in any direction. [ Douglas  Jun 28, 2016 ]
    Just the tweeter. I am no expert, but I believe that is all you need given the sounds waves travel differently depending on the frequency. That is why you can place a sub woofer anywhere in the room. These speakers sound and look great - practically invisible. [ Richard  Jun 28, 2016 ]
    Both the speaker and the tweeter are movable, but only a small amount. [ BEN  Jun 28, 2016 ]
    Both the cone and the tweeter are amiable, independently of each other. [ James  Jun 28, 2016 ]

    Just built 2 home theater systems that include Klipsh CD-5000CII, r-5650-SII, and 5650--WII. Also included subwoofers PSB CWS8, plus Polk Audtio 80F/X, 255c-RT, atrium outdoors, and finally to get Altos sound, I got ONkyo SK-H410. Everything is works and sounds great. All the speakers came from Crutchfield. I called before I ordered and discuss every speaker in detail with representative. Klipsh speakers are beautifully made. I also order two Denon Command HT receiver/amplifier. Tom [ THOMAS C  Nov 17, 2015 ]
    Absolutely. A surround sound system with those Klipsch speakers would provide very good sound quality. [ Larry  Nov 20, 2015 ]  Staff
    Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system. [ Krissy  Feb 25, 2015 ]  Staff
    I'm sorry, correction 50rms** [ Corey  Feb 25, 2015 ]
    I understand front ceiling speakers should be above the front tower speakers. Rear ceiling speaker is just behind seating area. Rear surrounds about even with seating. This makes my configuration a 5.4.2. That's 2 subs [ Earl  Jun 24, 2017 ]
    Emanuel, I was always taught that 10' is a good seperation between speakers. I used these speakers for my mid speakers between my front and rear speakers. I pointed the tweeters at my seating location, they work great. If you can't seperate the speakers that far try to place them just outside the seating area. I hope this helped.
