I purchased these speakers a while ago on craigslist, and it was probably a mistake, especially for $250.
Regardless, I am now restoring them.
As I purchased them, the grills are falling apart, the original 10" jbl woofers have been replaced by shitty radioshack woofers, the 10" woofer diffuser plates are missing, one of the bases is a bit messed up, one tweeter has a hole in it, and one binding post is broken.
Tweeter with hole, I have removed other drivers to clean speaker
Nice vintage JBL badging on tweeter
Nice vintage jbl badging on midrange
Cool vintage jbl badging on back of speakers
Also came with all original paperwork from 1971, including jbl product pricing guide.
These cost a whopping 288$ each in 1971. The legendary paragon cost a whopping $2500 though, or about $16000 now. Fun fact, the designer of the Paragon, Arnold Wolf, also designed the exclamation mark logo of JBL as seen throughout the 60's, 70's, and 80's, and is only slightly changed now.
My progress on these so far:
Cleaned out inside. Removed all fiberglass, and 2 dead mice.
I just ordered a new (used) tweeter for the one for $50. So already $300 in.
To do list: Find 2 JBL LE10A woofers, they come up on ebay now and again. I hope to score a pair for under $200. Rebuild grills using a frame and speaker cloth. I like the cool retro circles on the current one, but pretty hard to reproduced. Its made of a weird mesh plastic covered in fuzzy material, but has become brittle with age.
Cool reading on the JBL Aquarius:
