I'd love to see the specs of this speaker system and crossover schematic. Were the "for Japan only" speakers built in Oklahoma City by Altec Pro? Was there a whole line of these that are now pretty much forgotten over here in the U.S.A. (no specs, no schematics, very little info at all)? Anyone know the name/model # (or have any info/pics) of any other "for Japan only" Altecs? Were they primarily made in the mid 80's or were they in production during a different time frame?
