    Caliber In Wall Speakers 5.25 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.


    • Light and rigid, well balanced, yellow woven Kevlar® cone woofers for distortion free reproduction
    • Oversized magnets for more impactful bass
    • 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
    • 50 watts nominal and 100 watts maximum power capacity ensure that these drivers won't be overdriven or easily blown out
    • 8 ohms standard impedance ensure they can be safely driven by even the most modest home theater receivers

    Perfect speakers for me

    • ATinOP,

    Pros: Good quality, fast shipping, easy install.

    Cons: None

    Great speakers and easy to install in existing wall cavities. I installed them in our master bathroom for listening to the morning news and for my wife's bathtime tunes.Install was easy with simple hand tools. I painted the trims and grills to match with latex wall paint. I added fiberglass insulation to protect the adjoining room from backfired sound. Speakers are at 6 feet above the floor. They sound fine for this application. Not boomy but have good sound for wall speakers.

    Unbelieavbly excellent

    Pros: Excellent sound reproduction. Crisp highs and bassy lows. Very easy to install. The price for this quality of speaker is excellent.

    Cons: None so far.

    Building a new home, I was looking for 11 pairs of ceiling speakers for music throughout the house ... and two pairs for side and rear surround sound speakers. Because of other reviews (and my past experience with Monoprice) I decided to get these speakers. Their performance blows me away. They are crisp and clear, and the bass is astounding for the type of speakers (you would want a sub-woofer, however, for extra oomph). My electrical contractor who also does home entertainment systems was reluctant when I first told him I was buying these speakers. When they arrived, he said they looked OK. Now that they are installed, he is extremely impressed and said he will recommend them to clients who are looking to save some money and stil have an excellent sounding system.

    Really big

    Cons: Name is misleading regarding the size.

    I guess I should have read the fine details. I can't comment on how good the speakers are, but I will say that the size is not 8 inches. The full size is more like 14 inches. I was hoping for something smaller for the space I need to use them in my theater room. Not sure what I will do now.

    Hello Timothy,

    Thank you for your review and I am truly sorry for the inconvenience you've encountered. Can you please let me know what you mean by not it being 8 inches? If they are double the size then you may have gotten a wrong item, please let me know, thank you!

    Great sound poor install

    • Tim Whipps,
    •  Chanhassen, MN 
    • 2/11/2016 8:43:58 AM

    Pros: Great sound and Price

    Cons: Wall mounting clips are terrible.

    Love the speakers for the price as they have great quality and sound, solid speaker. The one problem is that the plastic wall mount clips are cheap and need to be enhanced as I had 2 break on me and they are not the best design. I also painted the screens and molding to match my wall and they turned out perfect.

    Great Sound

    • ChopperMario,
    •  Akron, OH 
    • 1/14/2016 1:20:06 PM

    Pros: Great Sounding
    Good Looking

    Cons: Only thing I could complain about slightly is the quality of the spring clips that hold the wires, they are little weak but not worth knocking a star off.

    I bought these yesterday (1/13/2016) they were delivered by noon today (1/14/2016) to my house in Ohio. I installed them in less than 20 minutes start to clean up and am listening to them now as I type this review. These speakers replaced some Bose shelf speakers that I had in my office temporarily and I have to tell you, they sound every bit as good as those if not even a little better.

    I have some higher end inwall speakers throughout my house and I have to say the finish on these are as good as the rest of the ones in m house.
