Ohm Speakers, thoughts?

Thanks for the info, Dale.

I've had steadily growing interest in the Walsh speakers for a few years now as a result of the serious room acoustics/placement problems I've had with varying pistonic speakers. I'm just tired of the hassle. And when things are finely set up properly, I really hate being confined to, and the only one to enjoy, the "sweet spot".

A few questions about your "A" & "F" TLS speakers:
Fequency response & impedence of your improved models?
What is the safe max power handling?
What kind of safe SPL output are they capable of?
Recommended types of amps and power output?
Any minimum room size requirements for best sound?
What is the sonic difference between your "A" & "F"?
And finally, what is the price for the two models?

Quick question for Dale. I owned a pair of Ohm F speakers back in the mid-1970s and absolutely loved them. As noted earlier in this thread, I auditioned a pair of 200s a few years back and though good, just didn't have the magic I remembered.

Unfortunately my current listening room would be unable to handle the large footprint of a F-sized TLS. Are you contemplating any smaller models based on this driver design?

I missed my chance to buy the Ohm speakers back in the 70s, but have always been interested (in an engineer's way) in the principles involved with the driver. I always knew that it was made up of several cones of differing material, but the complexity described by Dale is daunting. My concern would be performance changes over time and use as all the various tweeks age. Slits with sealant frighten me.

My thoughts exactly. It will be interesting to read the independent sonic performance reviews after a year of use.

Always wishing the best for anyone following their passion, especially engineers, I hope they turn out to be great.

Oh, well, I'm back for at least one more go-round!

Could "piston" the CLS piston drivers used in Ohms Walsh line speakers actually be an improvement in some ways in regards to sound as well as perhaps in reliability over even a perfectly functioning F or even A?

Having never heard a pure Walsh driver, I can't say. But during a listening session with the F5s yesterday, I was reminded why I started looking to better my Maggies in the first place.

It wasn't just a search for a lower and quality bottom end (and easier placement in the room), but also the dynamics and impact of the sound. Properly set-up Maggies and their ilk are magical even at the lowest volumes, but they do not move a lot of air and create the air pressure differentials that I believe are physically required to reproduce a live performance,especially for large musical ensembles like a symphony orchestra or big band or even for loud emplified formats like rock, at realistic volume levels.

These types of music require a speaker that can create significant air pressure differentials in the room, in my opinion, like a larger dynamic speaker does, which is why I jumped off the planar speaker bandwagon in the first place to some extent. I like the "magic" detail and clarity of these designs (like Maggies) however, especially at lesser volumes. Good monitor speakers can compete in this arena but are still to small to really excel in delivering realistic "oomph" to the music when needed.

So my question is, could the Ohm CLS driver, based on the Walsh design, be superior to even a perfectly constructed and/or commercially viable Walsh driver (at least any that have been built to-date or that are even remotely commercially available) in terms of dynamics and impact?

I do not miss my Maggies with the F5's. The sound has a similar presentation but with "oomph". I had a magical moment just yesterday unlike any I've had prior with my systems with the Concord Jazz CD recording of "The Classic COncert Live" with MelTorme, GErry Mulligan and GEorge Shearing. When I closed my eyes, Mel Torme and the big band were performing in my basement family room! There was one extended note in a vocal finale where I had to look around to see what was happening! I thought maybe someone had snuck up behind me! It just totally transcended any vocal renedering and listening experience I recall! Outstanding!
