How to Paint Speaker Grilles

Look no further for one of the world's most versatile and compact stereo and home theater speakers on the market. The M3 in-wall delivers powerful bass, outstanding treble, and award-winning musical sound for under $400. Its powerful 6.5-inch aluminum-cone woofer and 1-inch titanium dome tweeter deliver crystal clear vocals, driving bass and shimmering cymbals. Hear what a difference 25 years of audio research makes in loudspeaker sound.

The M3 in-wall is ideal for customers who want hi-fidelity sound that doesn't take up any floor space. The new M3 in-wall provides the kind of transparent, neutral, wide-range sound you expect from Axiom in an almost-invisible enclosure. The M3 in-wall speaker preserves the sonic signature of its bookshelf equivalent, the award winning M3, and adds a slim profile - just 5/8ths of an inch with the grille on, which is a perfect complement to today's modern low-profile plasma and LCD TV screens.

Hear the Difference

Standard in-wall speakers all have their parts slightly inset behind the wall plane, which may degrade sound quality. The M3 in-walls are the opposite - their parts protrude slightly from the wall's surface. The M3 in-wall features a fully integrated enclosure that recesses into the wall, combined with an attractive small exterior baffle which keeps the speaker's woofer and tweeter away from the sound-degrading effects of the wall's front surface. This makes them the first in-wall loudspeakers to have the same midrange detail and imaging as a similar bookshelf speaker sitting on stands.

Here is what you can expect from the M3 in-wall in both stereo music and home theater settings:

"I'm really in a state of disbelief because these little Axiom speakers have no right to sound as good as they do. They are an outright steal for the money!" -- Doug Schneider,

"Good luck finding anything remotely as good for the price. I think they are better than any B&W, Klipsch, Infinity, Technics, Bose, JBL and Sony models I have heard in this price range." -- A. Colin Flood,

Easy to Install

The speaker has an efficient built-in clamping mechanism that anchors the speaker firmly to the wall or ceiling when the screws are tightened. Mount it in the wall or the ceiling – it's your choice.

Recommended: You'll enjoy enhanced and extended deep bass response if you mate the M3 in-wall with one of Axiom's powered subwoofers.




Industry Reviews

Industry Reviews of the M3 Family

"the level of resolved detail the M3v3 provide across the spectrum is pretty dang astounding. . . I was blown away to find out they were $348, especially when considering their performance."
-- Adam LaBarge,


"The performance left us speechless... The M3's would work splendidly in a two-channel stereo system or as the main speakers in Axiom's Epic Master home theater speaker system. With wonderful performance and very attractive looks, all at a great price, you can't go wrong with the Axiom M3 bookshelf speakers."
-- J. Walker Clarke, Consumer Guide


"The Axiom speaker sounded very good at low volume levels and jaw dropping at high levels. These speakers can lull you or rock you; it's your choice."
-- Ray Adkins, Audioholics


"Anybody looking for high quality, very low cost loudspeakers, should listen to the Axiom's - good luck finding anything remotely as good for the price."
-- A. Colin Flood,
"Through every type of music that I threw at them, the M3s performed far beyond my expectations and I am still taken aback by how clear they were . . . flawlessly articulated . . . absolutely amazing."
-- Dale Rasco,


"The M3 is a remarkable little speaker for a very attractive price."
-- Ian Masters,


"...these little Axiom speakers have no right to sound as good as they do."
-- Doug Schneider,


"...phenomenal. In fact, from a passive two-way monitor, you can't really get much more performance regardless of price!"
-- Srajan Ebaen,

Customer Comments

Customer Comments about the M3 Bookshelf Speaker Family

Below are just a few of the many reviews that our customers have been kind enough to send us.

I researched these bookshelf speakers big time as I am fussy.
Hooked these to a multi-channel Sony AV receiver.
Hit the play button.
I'm writing you with my mouth still open.
WOW, Thank you for this great little speaker.
As a Canadian I'm proud of you, Great sound, solid feel. great service. Keep up the exceptional work.
-- Rae F., AB


As a recording engineer I am very particular when it comes to audio equipment. I couldn't be happier with my new M3s. You guys make a suberb speaker and the service was flawless. Keep it up!
-- Noah H., CT


Beautiful! Uncompromising quality, value, and performance. The M3s sounded great right out of the box. I could use words like, clarity, balanced, refined, transparent, but the highest compliment I can give is to simply say, they moved me.... I'm still smiling! Highly recommended.
-- David S., VA


The speakers are fantastic! Tthe M3s are the perfect small monitor, especially for European (small) spaces.
-- Adam J., U.K.



I recently purchased a pair of your M3s...all based on research... from testimonials to professional reviews. Time and time again your speakers came up winners with high recommendations; the messages were consistent, give them a try, you won't be disappointed. I'm sending this bulletin today to all who are considering an Axiom product: DO IT! It's all there, imaging, soudstaging, build quality and clarity. I looked at most of the competitors; PSB, B&W, Paradigm, Mission etc. all were much higher priced, but not even near the value Axiom is delivering. This is my first purchase from Axiom and I guarantee (to all) this is my new speaker company for years and years to come. Your product is exceptional. I'm looking like an audiophile genius.
-- Rich D., NY


I was worried about ordering speakers which I never listened to. I read many reviews about the M3 speakers and decided to take a leap of faith. I am a novice at home theatre systems but when I plugged these speakers in I realized how exceptional these speakers were. My leap of faith was not in vain. I am extremely happy with my choice.
-- Desroy F., NJ
