History on ohm A's and F's.


I panned through the threads and read how the old ohm a's were remarkable.
Would like to hear more about this and other ohm speakers.

I have 2 pairs of Ohm F.

All 4 speakers need repair as the foam disintegrates over time.

With proper power, let's say Chernobyl, they are among the finest loudspeakers I've ever heard.

Ohm A was basically a prototype. It was a 16" Walsh driver as opposed to the 12" Ohm F.

I believe very few pair were actually made available to the public.
Extremely difficult to recone.

There is only one gentleman I would trust to do mine.

He's located on the east coast near Philadelphia and doesn't get involved anymore due to the time and complexity involved. I even offered him one pair to keep in exchange for one repaired pair (plus his parts cost and labor of course). So far no interest.

But I keep them hoping he'll change his mind.
The 5-S3 is a nice speaker, a good value.

However, it is not an Ohm F but nothing else is either.

The F is among my favorites of all time which includes Apogee Duetta, Quad 57, and Magnepan 20. You can see I am partial to panels or speakers that replicate the imaging of panels.

One drawback to the F was the lack of SPL. I believe the sensitivity was around 82dB. Very few amplifiers back then could drive them to rock and roll volumes that we were accustomed to vis a vis the other contemporary speakers such as ESS, RTR, Infinity, JBL, etc.

I remember listening to my Phase Linear 700B in 1973 getting sucked dry during the opening heartbeat from Dark Side of the Moon. Even at reasonable SPL the Phase Linear was gasping for breath and out of gas.

Great memories of the speakers and the recreational medication.
Mapman,
I heard them at a customer's house with a pair of Pass XA60.5 amps.

I can't give you an honest comparison for 2 reasons. First, I haven't heard a pair of properly driven F's for almost 20 years and it wasn't in the same room as the 5-S3 which is critical. Second, and more importantly, our "sonic memory" is quite poor. Any comparsion based on what was heard 20 years ago is not worth talking about now IMO.

Sorry.

Not true.

See "This Side of Paradise" and "All Our Yesterdays" for an emotion filled Vulcan.
