OHm micro walsh series...

Those don't use real Walsh drivers. Walsh drivers look like "pylons" or "road cones" for lack of a better term.

As t Holzhauer's comments, once you hear a "true" Omni ( NOT a driver that is manipulated to reflect signals ), you'll never forget the spaciousness and depth that they are capable of. Sean

Ohm's own literature / info on their current line of speakers clearly states that these speakers are NOT omni-directional. They may sound more "diffuse" than other designs though due to the lack of direct radiation from the inverted mid-woofer. Other than that, the only "Walsh" driver that i know of that would fit inside of one of those "mesh cans" would be a Walsh tweeter as used by Infinity back in the 1970's.

As to the Morrison's, they are based on Stuart Hegeman's designs. The manner that the woofer is loaded within the cabinet is different from any other design that i've seen. The easiest way to describe it would be to think of a combo transmission line design mixed with internal Helmholts resonators. This approach has a LOT of potential from what i can tell based on the limited reading i've done about it. Sean

The use of the word "coherent" in this specific sentence may not be the most appropriate word for what they are trying to describe: "The Ohm Walsh Loudspeakers utilize unconventional technology to provide a less expensive speaker which is substantially more efficient and less critical of room placement, but still coherent over a wide listening area. By that, what i'm trying to say is the sound produced by such a design is NOT coherent so much as it is "equally diffuse".

While some may wonder how the sound radiating out of the rear of a mid-woofer combined with a forward firing tweeter could be "equally diffuse", that is simple. All of the sound that one hears is "leaked" through all of the holes in the metal canister and the material that lines the inside of that "cage". As such, the "beaminess" of the tweeter at higher frequencies is nullified due to all of the diffraction / internal reflections taking place. The end result is that one hears the sound eminating through the holes in the canister, not from any single driver. There is no direct radiation, hence everything is "equally diffuse", which is the opposite of providing a point source of radiation that exhibits a "coherent" wave-front. Sean
