    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

    PROS: Well worth the money, a must have in-wall speakers, thank you monoprice.

    Work great!
    These were easy to install. There's a cardboard template that you push a perforated center out of and then just use to trace on the wall. There are two perforations, so be sure to push out the smallest one first and test it on the speaker before pushing the next one out, if you need to. Pretty straightforward. The screws and tabs to secure to drywall work great. Easy to remove the grill for installation and for inserting a cover in the event you want to paint them to match the wall. They sound great and have a 3-position switch for padding the audio a little. If you want to have some good sound and not need stands or speakers out in the room somewhere these will be great for you.

    I'm sure they're not Bose quality or anything, but most of us aren't Bose quality either. )

    PROS: Price.
    Easy install.
    Great, rich sound (for the price).

    Great sound even better price
    Unbelievable sound, put in 2 pair of these with the micro flanged center channel and the 5 1/4 inch ceiling speakers and the sound is amazing. Very easy to install, look great and I am very impressed with the sound quality. Great service as always, there is no other place I will go for AV accessories.

    Well worth the money..
    Debated for a good 10 days whether to go with these 5.25 or the 6.5 Kelvar or the more expensive 6.5 Polk Rc-65i knockoffs. Price won out because after all this is just a purchase for my garage workshop. Glad I got the 5.25 Kelvar because they are more than perfect for my use. I've got expensive in-wall Polk's in the house, and these are very impressive. And to top it off I'm only driving these with one of those $22 Lepai 2020A+ little amps. Sure beats the clock radio I'll be spending a lot more time in the workshop from now on.

    PROS: Sound to price ratio is off the charts.

    CONS: Grill is a bear to get back on. Hope I don't have to take it off cause I'm not sure it will come back off.

    These speakers are just great! Awesome price, and quality. I'm using them with Monoprice's slide volume control for a multi-room audio set up. Must have especially at that price!

    PROS: Great sound!
    Great Price!
    Great look!

    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

    Great for the money
    Used as a center channel application in a lower/mid range theater install. Great for the money

    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
