    Caliber In Ceiling Speakers 8 Inch Fiber 2-Way (pair)

    Monoprice brings custom in-wall speakers to new levels of affordability with our line of Monoprice Brand Premium in-wall and in-ceiling speakers. These new high fidelity units deliver the high quality craftsmanship and construction you've come to expect from Monoprice brand products at a fraction of what you would expect to pay for them retail.

    In-wall and in-ceiling speakers allow you to expand your listening environment throughout your entire home as well as remove the clutter of giant box speakers giving you back your living space. In either case it's a win-win situation for those who desire high fidelity and those who put emphasis on decor.

    DuPont™ Kevlar® fiber cones are light weight yet extremely rigid providing very precise audio with minimal distortion normally caused by cone flex. Our Kevlar® speakers are matched with an equally precise silk membrane dome tweeter made of titanium fiber thread and a high quality crossover network to ensure high fidelity and low distortion. The lower distortion levels allow the speaker to be driven harder and handle higher peak power levels. The main benefit our Kevlar® speakers are the clarity and fidelity at which they produce audio.

    Note that you can improve the bass response and overall sound quality of in-ceiling speakers by using an enclosure. The Monoprice In-Ceiling Back Enclosure (PID 11942) is designed for use with this speaker.


    • Light and rigid, well balanced, yellow woven Kevlar® cone woofers for distortion free reproduction
    • Oversized magnets for more bass impact
    • Precision titanium silk membrane dome tweeters for sweeter highs and pure sonic clarity
    • Pivoting tweeters allow you to point the acoustics to the prime listening position for a more accurate and immersive sonic experience
    • Adjustable crossover switch allows you to match the speakers to the sonic characteristics of your listening environment and the location in which you place them
    • 80W nominal and 160W maximum power handling capacity ensures that these speakers won't be overdriven or easily blown out
    • 8 ohms standard impedance ensures they can be safely driven by even the most modest home theater receivers

However, it is representational of the steps, tools, and types of procedures that would be used for the installation of any in-wall or in-ceiling speaker and is included on this page for reference purposes only. Please refer to the installation instructions of the in-wall or in-ceiling speaker you have for the specific dimensions and installation procedures.

    Great bang for the buck

    Pros: -Price
    -Ease of installation
    -Sound quality

    Cons: -Nothing yet

    Recently installed these for use in a Home Theatre setup. While using these may not be the ideal, audiophile-approved configuration, the sound quality and performance at this price can't be beat. I'm using six with the enclosures and I couldn't be happier.

    Pros: Good audio quality

    Cons: Cheap mounting screws. Much larger hole needed than you might think.

    These are nice speakers. I was careless in my research and had visions of replacing my 5 1/4" RV ceiling speakers with these. No way would they fit, and because of the small size of the plywood backing glued into my RV ceiling there was no way I could enlarge the hole without tearing up the ceiling liner and damaging some of the wires in the area. Also, the four mounting tabs do not go less than 1/2", so you can't mount them to anything thinner than that (not a problem for sheetrock, but RV ceilings are less than 1/4). If you tighten the mounting screws, be advised one of mine siezed, the soft screw head stripped, and I had to drill it out.

    Shockingly great speakers for a shockingly low price

    Pros: 1. Sound Quality
    2. Build Quality
    3. Ease of installation

    Cons: This is a huge con: Please redesign the treble cut switch so that it's accessible from the front of the speaker after removing the grill. It's incredibly frustrating to have to uninstall the speaker and then remove the (optional) back enclosure just to experiment with which setting will sound best.

    I purchased 3 pairs of these along with their matching enclosures (PID 11942) for use in my kitchen, dining room, and garage. They arrived faster than expected, and there was hardly a scratch on the very ample packaging. My immediate unboxing impressions were: wow these have some heft, and these might look too large in my ceiling.

    I've had these installed for about a month now. Installation was straightforward. The back enclosures are an exact/perfect fit. These speakers are very bright sounding, so I strongly recommend (as did another reviewer) to just go ahead and set the treble cut switch to -3. I didn't do that, and ended up uninstalling all 3 pairs to make that change and install them a second time. Also, despite having an overall 11" diameter they don't look too large in my spaces. I have a relatively small dining room and kitchen with 8' ceilings, and these still manage to disappear.

    These speakers sound fantastic! They provide a pretty wide sound stage and have great bass, clean mids, and detailed highs (at the -3 setting). I did not listen to them without the back enclosure installed, but am convinced they do indeed improve sound quality (and also keep the blown insulation off of the speakers). I'm powering them with a 65wpc 6 stereo zone amplifier. They can play loud and very clean (louder than we need). They've brought a lot of joy to our family and are used daily.

    Pros: Sound, price

    Cons: Lows are lacking, better with enclosure

    Running 20 of these at my office, 2 at my home office. Was surprised by the quality. Mids and high sound great lows not so much. Added the enclosure to my home office and lows got better. Highly recommended.

    Cons: Grills were a bit difficult to paint, but I probably should have thinned the paint some.

    I'm using these in combination with the 6 zone audio multi-zone amp/controller and it works great.
