I received my mtm Omni last week. As Seth said, one speaker arrived dinged up inside a dented box, with a loose crossover. Despite that, the speaker played normally. I put them on 20 inch stands I happened to have on hand that fit them perfectly. They are placed about two feet from the side walls and three feet out from the wall behind them. They have plenty of room to breath, and indeed, they have an airy, clear sound. They are very neutral, uncolored, and revealing, imo. The bass is what you might expect from a stand mounted speaker of this size, but the sound is well-balanced, and I did not miss the deep bass on the recordings I listened to. In fact, I'd say you actually get surprisingly deep, and tight bass considering the size of the drivers. Overall, I like them very much. The drivers on top of the speakers certainly give them that omni illusion which is excellent and very enjoyable. You don't have to sit in a sweet spot to get the best out of these speakers. I don't pretend to be an audio reviewer, and am just stating what my impressions are, but I can recommend them highly. I slid my big floor standers into the corner and will be listening to these speakers for the foreseeable future.
I might add that the binding posts are the same propeller posts you find on the Virtue amps.
Addendum: The speakers continue to sound even better as they get some break-in. Very listenable, and a steal at the asking price. They have a rich, full sound.
