Vintage JBL Floor Standing Speakers

What kind of money are you looking to spend? 4345s/4350s/4355s would be the way to go if you can find and afford them. They will be cheaper than Paragons or Hartsfields and offer way more fidelity.

For a sampling of vintage JBLs and prices (though some are too high for what they are), other than the "bay" check C/L within the Los Angeles/Orange County area.

JBL L100 classics.  I almost bought a used pair of the recent reboot with the stands even though I had no where to put them.  My wife talked me off the ledge before I could buy them.  I still want a pair.  Maybe when she goes out shopping…

Buy my C34 Hartfield 

I just bought, redid and sold both a pair of Jubal L65s and L100s. It definitely improves the speaker to put in some better hardware and to update the crossovers but I really hated the sound of both these speakers. What they did do well, especially the Jubals, is play loud. In fact in some ways the Jubals made everything sound kind of like a live performance. So before buying any older JBLs make certain you like this West Coast kind of sound. I thought the L100s had absolutely no redeeming qualities. They just sounded odd. 

My guess is that there exist much better, more modern representations of what people like about JBL. I am not trolling just trying to help.
