    5-1/4 Inch Fiber 2-Way In-Wall Speakers (Pair), 50W Nominal, 100W Max

    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

    I installed two of these speakers for my 7.1 surround sound. They are great, I will be getting two more.
    Installation was easy, no problems.

    Surround Sound Oh My

    Pros: Sound, ease of install, sound

    Cons: none to date

    I used a pair of these for a suspended ceiling mount for my rear speakers of my surround sound, and oh my what a great sound. The only problem was the ceiling tile wasn't strong enough to hold the weight so I had to reinforce with some plywood, but very happy and surround has never sounded better.

    Great speakers

    • Anonymous,

    Pros: Small size and easy to install

    Cons: None

    I had some strange stud spacing which dictated that I had to buy these small speakers for my 25' x 20' family room. I was initially skeptical about whether these would do the job or not. I was replacing a set of Polk FX300i's and let me tell you these speakers are fantastic. As far as the screw issue is concerned I did what other reviewers had recommended and just screwed them all the way in then out before installing. Highly recommended!
