Hi poolandspa,
I've not heard the Ohm Micro, but the company has an interesting history. Some 35 years ago, Ohm, which began as a house brand, produced a costly speaker (the Ohm F) using the Walsh driver, which claimed to radiate a coherent 360-degree wavefront. At the time, it was impressive and vastly superior to things like the Bose 901. The Ohm F produced a flattering almost omnidirectional soundfield from a 2-channel source. It lacked directional precision but made up for that with its enveloping soundfield, rather like what you'd experience from some of the better Mirage Bipolar and Omnipolar models. In later years, Ohm dropped the Walsh driver and substituted several angled tweeters facing upwards combined with a conventional woofer.
Some of those speakers were quite good, although I don't recommend omnidirectional speakers for front channels in a multichannel home theater music system. Movie soundtracks and multichannel music discs are mixed with direct-radiating front speakers to achieve precise imaging. If you plan to listen only in stereo, the Ohm may be quite satisfying, in the same way that Mirage Bipolar fronts can yield a more expansive soundstage. But you do sacrifice precise imaging--that's the trade-off. And vocals and solo instruments will often seem to be spread over a broad space between the two speakers.
Regards,
