Setting New Standards In Size and Precision

MartinLogan design and engineering has translated its unrivaled ESL technology into just one square foot of floor space.

With a footprint of less than one square foot, Aeon delivers the highest resolution in detail and image with dramatic bass attack from its new, state-of-the-art woofer, next generation enclosure materials and advanced construction techniques. The world's most accurate transducer—the MartinLogan ESL—and this radical new woofer set new standards for precision. At the crossover point the woofers absence of distortion rivals the unprecedented resolving ability of the electrostatic panel.

These speakers were purchased 10 years ago by a family member. They were gifted to me in June. My former speakers were ProAc 1S's. These speakers are very similar sounding. Both have same bass energy, same smoothness, same peculiarities of placement, same mid-range focus. The Aeon's have a less in your face sound. Bigger sound-stage. More depth. Slightly better imaging and detail. Currently using a Cyclops amp which gives the speaker that " alive " sense of sound. Couldn't be more pleased with Aeon's. Great tech/ customer service.

Aeon review
Have had these speakers since 2003, i.e. 10years with no problems whatsoever. Very reliable. Great sound. My room is not too big so these are sufficient and can play surprising loud when called upon. I have added a B&W sub-woofer (10") which helps to round out the sound in a small room. I get a very full sound without having to over power the room. These speakers are easy to listen to and very transparent. Great product!
