Sonographe SL-21 speakers


I am not really asking a question on these speakers, since I may have had the only pair in the whole country. I just want to make a few comments on these fantastic little speakers.

I purchased these speakers by chance, I heard about them and drooled over them in the late 80's, but I could not afford any high end gear at that time.

After spending hours searching up and down on the internet, I couldn't find diddly-squat on these speakers, but there are no shortage of info for the Sonographe SA-120 and the SP-1, even the SG-3 is mentioned quite a bit on the net, that really makes me sick.

Anyway, the SL-21 has very attractive real oak veneer, the front and back are sloped, hence involved some time-align design, but like I said, I could not find anything on them. Even when I called C-J, the guy named Ed who handled vintage C-J equipment couldn't tell me a whole lot about them, at least Sota could tell me quite a bit about the SG-3 for crying out loud.

The SL-21 has very wide soundstage and solid bass for it's size, 6.5" woofer and 1" soft dome tweeter, and a 1" port in the front baffle, they also have very nice midrange. The speakers virtally disappear from the room while playing, that proves these speaker are well designed. During the knuckle test, I heard no cabinet echo or resonance, very solidly built, that tells me they are well damped inside.

If anyone who know about them, please charm in. These may be the only pair that left in the country, and they are not for sale.

the gentleman(can't remember the name) that designed cj's speakers left and started his own line, which failed too. they all ere outstanding. sota's panorama line were incredible as well. two unit sats and subs thats outwattpuppied the watt-puppy...once again they didn't last.
I believe Dave Fokos designed speakers for C-J . I do not know if he designed SL-21.
I own other speaker of his design Icon Acoustics model Parsec. They sound great. Icon Acoustics was his own company. After IA went out of business Fokos worked for Boston Acoustics and Bay Audio. Do a search for Dave or David Fokos.
Quote from inc.com :

“In June 1984 (Dave )Fokos, fresh out of college, landed a job as a loudspeaker designer for Conrad-Johnson, a high-end audio-equipment maker in Fairfax, Va. In the next four years Fokos would be the principal designer of 13 speaker models for C-J, an experience he calls "an invaluable apprenticeship" for running his own show. Fokos founded Icon Acoustics in April 1989, believing the niche he sought had scarcely been explored.”
I have had a pair of the SL-21s since the mid 80's and people who come to visit are still astounded by the sound quality. They're paired with Yamaha separates from the same era (C20 pre-am and M20 amplifier). Unfortunately the grills have both "disintigrated" and, when I called Conrad Johnson I was told they could not find any in the warehouse. Doesn't matter..the speakers look great without the grills. I remember the first time I heard them. I was in an upscale stereo store in Cleveland (no longer in business) and I heard all of this great sound and I couldn't quite locate the source. It turns out all that sound was coming from two little boxes sitting on the floor of the store. They have wonderful musicality and a great sound stage...even better than my B&W's which are much newer.
I recently aquired a pair speakers that sound similar to these. A metal tag on back states manufactured by Conrad Johnson of Fairfax, Virginia Model Number LM20 Serial Number 0200268. The other speaker's tag is missing. They sound good. The cabinets are clean without moajor blemish. They are heavy and well constructed. The foam grill covers are good but not perfect. I am in Atlanta. I would like to know more about them if anyone can shed some light.
Does anyone know the exact Vifa Woofer model # used in these as well as the Tweeter model?

Also, does anyone know if the woofers were shielded or un-shielded as original?

Thanks :)
