4310 Prototypes Revisited

[CountD]

Just got back from a long trip up to Lake Tahoe to retrieve the 4310 prototypes (the C. Robert Fine JBL Monitors) that I purchased. I was able to interview the owner for more than 2 hours about the recording industry in the 1960s. The speakers are the real deal and include handwritten notes about their construction by what was an in-the-works JBL Pro division. The owner reminisced about talking to and ordering them from Ed May himself. Pretty awesome.

By looking at them they seem to be a real piece of JBL history that most people don't seem to know about until they showed up on that auction site. I have not had time to do much but will post more info and pictures as it is a great link to the 4310-L100-4311.

Very very cool - thank you for sharing all of this!

Great find. thanks for sharing, and YES post pics, even scans of the notes.

After looking through the notes on the back they are models C533WX - as I know now they are Model C533 with a walnut enclosure. Now that I know that they are C533's - which seems to make them the Robert Fine Monitor, does anyone know anything else about these other than the crossover schematic? Does anyone else own a pair? They obviously seem to be made to Robert Fines specs and sold to other people that had access. Thanks.
