Looking for info on SP Revelation speakers

They are really good speakers, and they were pretty expensive when new. I only heard the small standmounters once, but you have the big floorstanders. The designer focused on big dynamics and low distortion, and those solid wood waveguides are beautiful. Some were just black. He made some beautiful crossovers, which as I recall were sometimes visible from a window in the back. SP went under and he tried to start again under a different name, but that company failed as well.
I would consider those speakers a treasure.  

Thank you so much for the info...the back was not marked so i removed the panel and took some pictures of the inside. Do you think these are original? Oh and i also found a porn magazine wedged in the bottom 😬. What would you do to restore these to their former glory? Do you have any idea of the original cost?

That is one of my main concerns, it looks like there us no crossover, the speaker wires are haphazardly taped together,  and the speaker wire is jist coming out of a hole in the back panel. Seems a little low budger for speakers that are supposed to cost so much.

They sure are purty looking. 

I had a pair of these that were recently destroyed in a flood caused by the remnants of hurricane Ida. Mine had outboard crossovers. I had the crossovers on a shelf so they didn't get damaged. You are welcome to them if you need them.
