I picked up these Organic Audio Systems floorstanders knowing nothing about the brand, but influenced by the drivers installed, namely Hiquphon ow1 and Morel hu521.
The cabinets are decently made of what appears to be 3/4” mdf with a good thickness of maple veneer on both sides. The drivers occupy an estimated 0.31cuft volume at the top of the tower, ported with 1.5” x 5” long tube.
The crossovers are housed in the mid section, the components being glued directly to the enclosure without any component board. Film caps, (can’t see the brand), Mills resistors and three air core inductors of 16 or 18ga.
The lower third of the cabinet must contain some sort of ballast since they are very heavy, maybe 40 or 50lbs.
I wondered if these may be built from a kit, judging by the crossover section.
Any info will be most appreciated.
Stay safe,
Petr

I don't recognize them, but the fit and finish is above that typical for kits, and glued XO components without a PCB are quite common - all of the AR and KLH speakers I owned were that way.
That connector on the rear panel is expensive, so I suspect these were intended to be a serious effort. (Air core inductors and film capacitors say more of the same.)
Suspect you scored... Probably a small, low volume and obscure speaker maker. I was not able to find anything terribly useful on Google.

The only thing I could find was this:

It appears they may be DIY at a high quality. Possibly prototypes for a company that never got off the ground.
How do they sound?

Thanks guys. As mentioned the quality of construction matches the quality of the drivers, whether they were kit built or small production hand built. I’ve built 30 or 40 speakers and none were as good as these, construction wise.
Sound wise, spaced eight feet apart and eight feet to listening position, they present a very wide and high soundstage, crystal clear, great imaging, tight bass. No boxiness. Great for my smallish music room. Keepers..........until the next pair.

The inductors might be intentional - if you orientated them so that they coupled correctly, I think you might get a "free" increase in inductance. Could be useful.

Thanks pjblakey for the crossover.
edit: Now I am curious to reverse engineer the schematic and I just can't make which wire goes where, much less what the values are.
edit2: I had an idea that perhaps we could first evaluate original schematic by simulating and then may be get it optimized (?), if pj will consider such a stunt at all. Of course, prior to that, original crossover schematic is to be recorded so that everthing can be put back just as it was, anyway.

Lojzek....thanks for input. I would have to use a chisel or similar tool In order to remove the crossover plywood board. I’m not keen to do that especially since, after days of enjoying what is probably the most musically satisfying speakers I have owned. For $200 that is quite something.
It is the first Hiquphon tweeter I have ever heard. Same can be said about the woofer.
Just beautiful.
Stay safe

Even if you did not enjoy them, you certainly got a deal on those drivers.
The lack of an address on the label indicates a virtual, rather than physical company- not a problem; if they make more good speakers, they may grow up to become a real boy someday.
It does say a lot for their construction if you like it, Peter.

All caps appear to be Solen PB series. They didn’t appear to skimp on the build anywhere.
Other than the crossover not being readily removable. They are really growing on me.

Slowly, very very slowly. Some increased interest as been looking at the stuff xrk has been doing with the new Purifi woofer. My room is really too small for the OB plan, but with a little cabinet work and quite a few $$$ I could get a chunk more low end so I wouldn't need a sub other than for dino farts on movies and a healthy drop in distortion. This is tempting me considerably...
