M3 In-wall Speakers
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.
