RE: Vintage JBL Speakers - $1 (Anchorage)

This NEEDS documentation.
I cannot find any mention of a factory kit to "help" the L65.
(or any jbl kits) There is a ton of info on forums about the L65 but is have not seen any info on a kit.
"provide a larger sound for model L65/ Jubal" that is a very questionable statement and not backed up with any info.
The L65 needing help ? I am not saying this is scam but it is yet another CL post from this seller with NOT enough information (modus operandi ) to make an informed decision.
