Audio anachronism alert! I haven't heard references made to Ohm's Walsh drivers in a long time. I listened to these extensively about 25 years ago. They were truly a unique pioneering design with their own set of unique flaws, but the "Cool" factor was off the charts.
Ohm Walsh drivers are still made today but only by custom order for a person wishing to spend $2500 or more on a pair of speakers.
I frequently listen to a pair of vintage Ohm Walsh 2s which do just fine since I'm practically tone deaf after too much Cream & Zepplin.
Anachronism? OK, I guess, I was just going back to the golden Audiophile days.
I could have made a modern day reference to a quality pair of Yamaha's but nobody ever listens (listened) to them.
I bet you miss your Fs?
I had ESS AMT-1's (with the Heil Air Motion Transformers) and then bought a pair of Koss ES-9 earphones.
That, in a way, calibrated my ears for my next set of speakers, which turned out to be Walsh 4's.
