    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.

    excellent speakers, easy to install
    October 5, 2015
    really pretty good!
    Im a Polk Audio guy, pretty much every other speaker I own is a Polk. I was a click away from buying the RC-80i speakers for considerably more and saw these. I liked the reviews, and Ive had great luck with other stuff from Monoprice so I figured for the cost savings Id give them a shot.

    Im finishing my basement and using these as stereo speakers in an office. When I got them, I couldnt wait to hook them up and try them out. I hooked them up just laying on the counter - they sounded OK, but not fabulous. There seemed to be quite a lack of bass, I had to turn bass all the way up on the amp to get any at all.

    Because of my experiences with them in just open-air, I decided to build small boxes in the ceiling by sticking styrofoam insulation between the floor joists where the speakers were to be installed. The ceiling was insulated with regular R-13 fiberglass, so I shoved the styrofoam up against that, nailed it in and then used spray foam insulation to seal off the sides and cable holes and prevent any rattles. Got the drywall up today and put the speakers in. Installation was a snap and they sound pretty good! The bass has definitely improved considerably having them installed in the boxes in ceiling.

    Overall, for this price, these are a no-brainer. Id have liked to have the Polks, Im sure they are better...but I was able to get these speakers plus the A/B switch, volume control knobs, banana plugs, and everything else I needed for this project for what I would have paid for just those other speakers. Sounds like a deal to me!

    WOW suprisingly Good
    I purchased 4 of these for my basement bar setup and they sound great in a 350 sq. foot area. I have them all mounted in the walls at ear level except one is above the bar on a volume switch to adjust the output level.

    Monoprice vs Polk vs Speakercraft
    I recently purchased 3 pairs of ceiling speakers - Monoprice ($59/pr), Polk RCi80 ($150) and Speakercraft AIM7 three ($340) with a huge disparity in price for installation in different rooms for music and so I could hear TV in each room.

    Monoprice in large carpeted bedroom, Polk in large tiled bath , Speakercraft in tiled smallish kitchen. All appeared to have solid quality builds and were similar to install. Speakercraft was built with an enclosure and looked a bit slicker and had a slightly more solid feel and look with some features that were useless to me - Aimable woofer & tweeter. (all speakers look very similar once installed)

    The important thing though is the sound. In short, the Monoprice sound almost as good as the others. I don't normally listen to these speakers at very loud volumes where I guess? the more expensive speakers might stand out. But for normal listening I would say the that the Monoprice speakers are just a bit less "lively" than the others. The midrange doesn't seem to stand out as well as the others - but I suspect that has to do with their placement in a carpeted room vs the tiled rooms where the Polk and Speakercraft are.

    I do like music and I think I have a decent ear for quality (My main room system is Denon 2802 with Wharfedale and B&W's- each of the ceiling speakers run off the Denon). In short, the difference between the three speakers is negligible, especially for what I use them for. None of them have fantastic bass, which is expected.

    In summary, if money is an issue I would not hesitate to use the Monoprice speakers for music in all rooms. They are just SO much cheaper than everthing else and they definitely do not sound at all like cheap speakers. AT ALL.

    Also, I guess I was kind of curious as to why the Speakercrafts were SO much more expensive than the others. I must say that it is not the sound. I was expecting to be blown away - like they would sound 5X better than the Monoprice or Polks. But the sound definitely does not justify the ridiculously high price.

    in ceiling speakers
    I had prewired my living room which had vaulted ceilings and needed some in-ceiling speakers. I thought I would try a couple of these since for the price it was not too risky. I can say that for the price I am impressed. I use 4 of these for the room and the room is filled with music. I cannot recommend these enough.

    PROS: inexpensive, great sounding

    CONS: Be careful tightening the screws to secure the bracket (plastic)... over-tightening may break them. I didnt break any but could see someone doing so if they were not careful

    8 Inches Kevlar 2-Way In-Ceiling Speakers (Pair) - 80W Nominal, 160W Max
    I put these speakers in my study. The room has 12 foot ceilings and they fill the room with ease. When you first hook them up to your receiver they'll probably sound muddled....just adjust your settings and these speakers will come to life! I plan to order more for the rest of the house. Great product for a great price.

    PROS: Price
    Ease of installation

    Monoprice has the best products for the best price! My new home theater setup sounds awesome thanks to the 4104's running off my Onkyo 608. Add a subwoofer and all you need is a bowl of popcorn and enjoy. I have no clue why people think expensive equals better as these speakers sound better that the Bose speakers I tested at the Bose showroom!

    PROS: Cost definitely. SOUND QUALITY

    CONS: None yet

    Buy these speakers
    These speakers were very easy to install. Look awesomne without the grills, though wife wants them on, They sound like much more expensive speakers and compliment the front stage tremendously. Don't think for a surround speaker or distributed audio I could find a better speaker for the money or even 4-5 times as much as these were. Awesome.

    PROS: Ease of install. Looks. Sound.

    CONS: speaker mounting with spring tabs not binding posts. adjustments being on back of speaker not front

    Great Buy!
    I was going to entertain in a few days, but havent installed the speakers for my patio. When I saw these online I wasnt sure how great they would be. I e-mailed customer support on this item. I wasnt sure if I could install these out doors. They assured me that as lone as the element didnt get to them they should be fine. I mounted these speaker under my patio. They were really easy to install. The sound is awsome. As we entertained that night, everyone was impressed with the sound. After I told them how much I paid for them they were in shock. I would recommend these speakers to everyone. I couldnt be happier!
