hi i have three klipsch hersey hsm vintage models serial stamped into the steel speaker connection housing is #3150/3151/3884 last one being a wedge floor monitor all three are heavy 62 lbs each and and have aluminon around the speakers edges and corners - these came from a dirct factory sale in the 1980's late- they are much heavy and more powerful than the home models i had a few years ago -- does anyone know anything about value of these units - they have been used in a club for almost 40 years as portable patio speakers for a disco - outside they have signs of wear on the black wood parts but function quite well - club closed recently and i have these to sell any help on exact model types 1/ 2 /3 etc and valve to sell would be greatly helpful-- have not seen any of these on ebay just the home models that come up occasionally- these are much more heavy duty - and industrial in look - thanks
