    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

    Can these speakers be used in the ceiling?
    Craig H on Dec 30, 2016
    BEST ANSWER: I'm not sure if the internal of the speaker will work any differently, but I don't see why they would. Installation wise there is no issue, there are 6 clips to hold it on place, plenty of support for the weight of the speaker. Just make sure you don't have any wood in the way, the clips will not deploy if there is strapping or a joist too close, they are pretty flush to the drywall right on deployment.

    Awesome speakers
    I bought these speakers because I installed a new tv and the in-board speakers weren't quite enough. When I received them, they were bigger than I expected, which is awesome. When I hooked them up to my system, they sounded amazing. I am REALLY happy with them. I installed them and they blend really well with the walls. I love how they look, and you absolutely can't beat the price! Thanks!

    Placed two of these speakers as rear speakers of a 5.1 surround sound system. Now that the job is completed, they look very good and the sound is good also. The mounting did not go as easy as the video suggests so I have so I have some tips to make the job easier for you. The first problem was that it was not so easy to remove the grills for mounting. Use the enclosed removal tool and be prepared for a good tug. You will need 3/4 inch clearance from studs on each side of your wall hole for the mounting clamps. Getting the mounting screws going through the plastic mounting clamps was not easy to do by hand. as not to risk damage to the speakers, before attempting to mount the speaker in the wall, I removed the plastic clamps from the speaker unit and started the screws going, unscrewed, then replaced them on the speaker and screwed the unit in. The most difficult problem for me was placing the grills back on the speaker. The video makes it look easy. I had to use a pliers to bend in the edges and corners and,it was still a challenge

    Based on the other reviews I had quite high expectations, but was a bit disappointed. Since I love all my other Monoprice products, I am sending these back and will order the 8 1/2 inch version. I'll write a review on those when I get them

    PROS: Price: These speakers are good value for the money. Relative to other products e.g. Polk they cost about 1/3rd.

    CONS: The sound is rather disappointing. Perhaps I'm unfairly comparing them to the Polk RC85i which sound much better.

    Great speakers for the price
    Being the smallest rectangular in-wall speakers Monoprice sells, I was pleasantly surprised by the results. I actually wanted to buy the largest they had, but my wall studs totally dictated the size I could fit, so make sure you do as I do and locate all your studs and plan exactly where you will install your speakers before you order. I purchased 1 pair for the front and 1 exact same pair for the back of my 5.1 set up.

    The install went pretty much as easy as the related Monoprice video. Again, the most important thing is to make sure you will be able to install the speakers where you wish. The sound is good, especially for the size. The crossover switch is a great feature as well. I had some distortion crackling out of the rear speakers with a certain game I was playing, but adjusting the switch in each rear speaker eliminated that. I also liked being able to tilt the tweeters to any angle I wanted and I used that feature. I really don't know how much of a difference larger speakers would make, but the prices are so cheap, I'd say go for them if you can.

    PROS: Good sound
    Extremely low price
    Useful crossover switch
    Easy to install
    Adjustable tweeters
    Nice, simple look

    CONS: None

    inexpensive but worth more than the cost
    i installed these for my rear speakers in my homes 5.1 setup. Installation was a breeze and monoprice was quick to replace one of the speakers I was having issues with. For rear surrounds, the performance was more than ample. My marantz receiver has an auto tuning fuction with a mic but I had to turn the rear speakers down significantly. I would not hesitate to use these for in wall front speakers though I did not for my particular setup. I was certainly hesitant due to the low price, but they were recommended by a friend that installed them on his cousins 5.1 system. great buy and great value.

    PROS: Inexpensive, easy installation, adjustable tweeter

    perfect solution for large bedroom
    I was looking for something simple to replace the sound from my Samsung LED. In addition to this pair of wall speakers, i also purchased an in-wall CENTER Channel (Product ID: 4881). Together installed, i am very happy with quality of surround sound that is being produced from my Sony receiver. Installation took me 40 minutes and was very easy as the speakers come with clear instructions, a wall tepmplate and all the needed hardware. The most difficult part of the instal was deciding the distance from the center channel.

    PROS: The first set arrived with one speaker that kept cutting out due to a faulty wire connection. Monoprice exchanged the entire set immediately at no cost to me. I give them an A+ for customer service which is hard to come by these days.

    Needed some cheap good quality in-wall rear speakers. These are perfect and have a great sound for rear speakers. Easy to install and look professional, well, I guess they are professional.

    very easy set up and the speakers sound great. I use them for my zone 2 and they are a great addition to the basement

    PROS: great sound and easy to install

    CONS: none

    I put these in the kitchen for my wife...hooked them up to a Dayton 25w mini amp and they sound great. Based on reviews I expected good sound, but these are great. I am in the new home business and a lot of people pay a lot more for the speakers we put in our homes and get a lot less. These are a bargain.

    PROS: great sound, clean look, easy install

    CONS: none
