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. 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. The paintable finish also allows you to paint your speakers to match their surroundings.

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, SoundStage.com

"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, EnjoyTheMusic.com

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.

If you would like to have your speakers painted to match your walls we can do it. The upcharge is $150 for your entire order for this option.

Customer Reviews
Bought these M3 sealed speakers to fit into custom boxes for my rear surrounds. I have an old 1928 stucco house with walls that have almost no space behind them to mount these in the wall as they were designed. But since they are sealed, you can put them inside any box without worrying about modifying their acoustics. They really sound incredible as rear surrounds and musically they are a great match with my M80 towers when playing 7 channel music.

Great product, great people - keep up the great work!
- Andy M., CA
I love the home theater in wall system. I used m-22 in front, the m-3 in the ceiling rear, the vp 150 shelf center, and the ep175 v3 sub. It is an awesome setup. The surround stereo is also fantastic for music listening. I also put 4 m-3 speakers in the ceiling of a family room kitchen and have been impressed by the sound for stereo listening. The axiom products were easy to install. The email and phone responses were most helpful.
