First time poster. I have been dabbling in vintage stereo for a while, but have not owned any JBL's: Today, however, I received, for free, a pair of 2-way JBL 4301B Studio Monitor Pro Series. Cabinets are a little scuffed, but nothing that some elbow grease can't fix. Drivers and grilles look fine.
I have not been able to find much information about this speaker anywhere on the WWW, and was wondering if there are anyone here familiar with this model that might chime in. I have found from searching that the 4301B pro series has a consumer-market counterpart - L19. I am particularly interested in what wattage amp I need to use with these JBL's, what opinions you might have about their audio quality, and any MSRP and production year details. I am not looking to sell these so valuation would only be of secondary interest, if at all.
Also, any thougts on how to best clean those _blue_ grilles?
