Ohm Speakers, thoughts?

Unsound,

Some purists appear to not buy this, but Ohm clearly builds and uses Walsh design drivers. They are in fact not the same Walsh design as the original A's and F's, the first and somewhat legendary Ohm speakers to apply the Walsh design principles over 30 years ago.

However, there is no doubt in my mind that the current Ohm Walsh drivers are based on the same design principles as the originals.

Again, I could be wrong, but, I was under the impression that Ohm currently uses pistonic cones as opposed to the bending wave Walsh drivers.

Could you get good response off the back of a standard driver firing down into a cabinet?

If the answer is no, then they must be using something different than a standard driver.

If the answer is yes, then they've come up with a way to get "walsh sound" from a standard driver.

Either way is just fine by me. I only care about the sound.

I've never heard Ohm Fs.

I a/b compared the new Series 3 100 drivers versus original Walsh 2 drivers from the early 80's before I purchased the larger f-5s with the Walsh 5 series 3 drivers.

The original Walsh 2 drivers had significant and very noticeable sonic shortcomings when compared the the new Series 3 Walsh 100 drivers or even my "modern" Dynaudio or Triangle (with subwoofer) monitors.

Though inferior, I still enjoyed the original vintage Walsh 2s for many years still, mainly due to the characteristics of the Walsh sound.

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.
