Gentlemen,
I think you have completely missed the point of my long treatise and the purpose of adding to this thread above. There is no comparrison to the old Walsh "F" or "A" relating to the current products.
The current products consit of two standard pistonic drivers, one being an iverted woofer and the other being a dome tweeter. This arrangent borrows a very small likeness to true Lincoln Walsh design and for lack of a better word "tricks" your ears into hearing somewhat onnidirectional sound, when in fact, it is only 180 degrees in dispersion. The back wave is suppressed from the woofer and the tweeter fires only frontward at a 45 degree angle to the norm.
The current product uses a complicated crossover network and is not truly time and phase aligned nor is the sound coherent. The Walsh principal, IMHO, is the finest speaker principal ever discovered, only the implimentation of that discovery has ever been lacking. Had it reached its full potential almost all piston drivers would be gone.
This is not to say that Ohm Acoustics has not done a fine job with what they currently offer, but true Walsh drivers they are not.
A Walsh speaker consists of one steep angled cone made to behave like a transmission line. It has no phase or time distortion, emits in a full 360 degrees and the sound wavefront is fulluy coherent just like a laser beam. There are no crossovers whatsoever. Placement is not super critical and the sound stage does not wander. If there is a sweet spot, then it is extremely wide and very, very accomodating.
The Lincoln Walsh discovery lives on in my NEW presentation of the "Waslh TLS" series of drivers and systems.
