Ownership and Review of a pair of Ohm Super Sound Cylinder

Greetings all - I recently ordered a pair of Ohm Super Sound Cylinder speakers, or SSC-4900's. They are in the middle of the Ohm Walsh lineup, and are about 38 inches tall and the cylinder cabinets about 12.5 inches in diameter.

Specs are listed at 88 dB for a 2.8 V input, and a response curve of +/- 3 dB from 25 to 20,000 Hz. 

This whole process is part of a "high end, high value, USA made two channel system" thread I started a couple of months ago on another forum. The electronics are the PS Audio Stellar Gain Pre-amp/DAC and a pair of PS Audio M700 mono amps.

The PS Audio equipment has already elevated the Axiom M100's and Martin Logan Electro Motion ESL speakers in terms of performance. The Axioms have a "twin" available in Brick and Mortar outlets from Bryston called the A1's. 

For reference, other speakers which we have or still have in house include: Klipsch LaScala II's, Legacy Signature SE's, Infinity IRS Sigmas, Ascend Sierras, PSB Strata Goldi, VMPS Super Towers and a host of other speakers. 

The Ohm Walsh speakers have been something about which I have read since 1977 (the year I got the audio bug), but have never had the chance to experience. The SSC-4900's sell for $4900 per pair, though the name and pricing are coincidental. The "4900" is due to the idea that the speakers are "almost a 5000", but with less controls - one switch vs. 4 for the 5000, but also a lower price.

John Strohbeen, who is he president at Ohm and who has been with them for almost 40 years, was gracious enough to spend an hour talking on the phone about our room, the associated gear, and also that there would be a review thread. It was after this discussion that we decided on the SSC-4900's. 

I am purchasing the speakers, not getting a review pair. They are under the 120 day return policy. John is well aware that my daughter sings opera, my son is adept at classical guitar, and that live music is the reference. He was actually quite pleased about this. 

This will be fun (at least for me), and hopefully informative. Comments are welcome. 

I honestly have no idea what to expect from the Walsh sound. They are so different from other speaker designs that the only thing to do is set them up properly and hear what happens!

Not looking to argue at all myself. Looking at old pictures of Ohms, it simply had me wondering. What I have heard from their speakers I like them. As far as an off the shelf driver, Ohm (like most companies) don’t make their own drivers from what I know... so it’s a question I always ask/research when I look at new speakers. Most companies it’s "easily" discovered, with the Ohm, I’ve had a little less luck. My hope had simply been you took some pictures.

I’m all about the sound also. Really, simply wondering as I have considered buying some myself. Just so little out there on what woofer, tweeter, and crossover parts are used these days. I’ll admit, that is a little important to me. Sound is 85% of the equation, I suppose pride of ownership (and knowing that quality parts were used, and that the price was "worth it") is part of it for me.

NOT disparaging the speakers at all, I have really liked what I have heard.

I’m also not a huge Golden Ear fan either. We are on the same page here, it just seemed you were really into an in depth review, so I had hoped you might know the answers. Not a big issue either way. Won’t stop me from potentially buying a pair, I’m just a research nerd before buying.

Take this from an Ohm fan, I doubt the drivers are made in-house.  The "secret sauce" is in how the drivers are modified, loaded and positioned to both load the cabinet for bass extension and provide the bending wave effect that the original Walsh driver made famous.  Also, FWIW, I seem to recall hearing that the drivers were not all the same material.  For instance, my 2000s, which, I believe, use an 8" main driver, is actually made of aluminum, according to something I read on line (never asked Ohm about this; I don't really care).  There is nothing metalic about the sound, though.  That said, I have log wondered what my Ohms would sound like with a folded ribbon tweeter, since I like the way those Heil tweeters sound so much.  But again, Ohms are built to a price point, and very reasonable one at that.  So, I am certainly not complaining.

One cannot see the driver from inside the "can". It is a totally self contained unit with the same mesh on the bottom. Otherwise, I would have snapped a picture. Apologies, I should have mentioned this earlier.

I don’t know what drivers are used, but having owned OHM Walsh speakers now since 1982, I can say they they seem virtually indestructible  and never show any sign of strain or being over driven. More so than any other comparable speaker I have owned. And believe me I have run them pretty loud and hard on occasion. I do it these days with high current 500 w/ch BEl Canto Class D amps. They love it!
