Looking for info on SP Revelation speakers

That is a real shame! I wonder why someone would have removed the crossovers. They were really expensive speakers, and I do remember the outboard crossover option. It is very kind of bnut311 to offer those expensive crossovers.

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.
