How to Paint Speaker Grilles

Looking for hi-fidelity sound that doesn't take up any floor or shelf space? The new M2 On-Wall/In-Wall provides the kind of transparent, neutral, wide-range sound you expect from Axiom, without any of the compromises that plague other in-wall speakers.

The M2 On-Wall/In-Wall hybrid speaker preserves the sonic clarity of its bookshelf equivalent, the M2, and adds a slim profile that is a perfect complement to today's modern low-profile plasma and LCD TV screens.

Other in-walls rely on the wall cavity to tune the bass output, resulting in a speaker whose performance varies from wall to wall and room to room, and may even produce distorted sound in neighboring rooms.

Overcoming these drawbacks, the M2 On-Wall/In-Wall features a fully integrated enclosure that recesses into the wall, combined with an attractive exterior baffle portion that keeps the speaker's woofer and tweeter away from the sound-degrading effects of the wall's front surface. The speaker ports are cleverly hidden at the base of the outer baffle.

A supplied self-clamping frame anchors the speaker firmly to the wall when the screws are tightened. The series is available in a variety of attractively-finished front baffles to suit any decor.

Recommended: You'll enjoy enhanced and extended deep bass response if you mate the M2 On-Wall/In-Wall with one of Axiom's powered subwoofers.

Industry Reviews of the M2 Family

"I was stunned the first time I played the M2 ... Axiom has scored big-time. An inexpensive, micro-sized super-achiever."
-- Doug Schneider,


"far and away my favorite speaker selling for under $300.00"
-- Don Lindich, Q & A


"Character voices, music and sound effects sounded very crisp through the M2s. The M2s delivered exceptional imaging, clean vocals and a very detailed sound across the front soundstage."
-- Suave Kajko, CanadaHiFi


"The M2 and EP125 make a superb combination in a small room system... the M2 is a legend in the making."
-- Kevin Hunt,


"If it's not already, the M2v2 should be considered a classic... Axiom has knocked this one clear out of the park... they get my highest recommendation."
-- Clarke Robinson,

Customer Comments about the M2 Family

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

Our speakers sound great!!  Teamed with our subwoofer-sound is awesome!!! We will definitely buy again from Axiom!!
-- Raymond L., MN


We received our Axiom speakers and we are in LOVE with them! It is hard to believe such a fantastic, beatifully balanced wall of sound is coming from those two small speakers! If you close your eyes it is very easy to imagine that the vocalist and musicians are in the room with you. We are rediscovering our CD collection, anxious to see how each one sounds with the new speakers....fantastic! I will definitely be recommending these to anyone and everyone. Thanks for such a great product!!
-- Arleen Z., PA


Great product! Nothing close to it at twice the price.
--Alan D., CA


I received the M2i speakers today. My little system--Cambridge a300 amp-8inch Ar sub-M2i! I listened to Carmina Burana (Telarc) and it sounded wonderful. The old speakers, Boston Acoustics HD10, are much too laid back. I am very pleased, thank you.
-- Mike P., NY


Finally, I have "highs" that are crisp and clear without any annoying harshness.
-- Jeff L., NY


I'm really happy I tried my luck with you! Yesterday I finally tested M2i's with a good sub. I found myself listening my mouth open. Whatta sound!! Clear, neutral, airy and _soft_ YEEEES! I was smiling the whole day. I _definitely_decided_to_keep_the_m2i's._ Thanks! Once again.

Million thanks and bows to designer of m2i's!
-- Timo L., Finland
