Hello...
About a year ago, I answered a CL ad for a Pioneer SX-580 for $30 that I needed for parts. As I was leaving, he asked me if I wanted a Sansui cassette deck. How much? I asked. He said "free". I said I would love to have it. Then it dawned on me to ask if he had any speakers. He said, "you should of come earlier today, I took about 8 pairs to the dump....but I do have a set still in the garage, they were just too heavy to load by myself." To the dump? As we walked into the garage, I saw the back of them from 20 feet away, clearly (2) vintage JBL crossovers in both cabinets. Excitement....then confusion. The large cabinets were nothing I recognized as JBL. They were some kind of custom cabinets. As I went around to check out the front, I spotted some 077 slot/prism tweeters, and holes where drivers once resided(15" hole, and a 4" hole). I didn't want to get too excited, but I asked what happened to the drivers. "Oh...I have the bass speakers in the house....but they are in rough shape." As he went in to get them, the wife comes out with the horns holding them on her shoulders like they were dumb-bells! I could not believe it! In my head, I quickly add up the worth.....$2,000-3,000. I'm thinking he is going to say at least $1,000. Before I ask, he tells me that all the equipment was his fathers who passed a few years prior. The father was a NASA engineer and quite the audiophile. He constructed the cabinets about 10 years prior to his passing and enjoyed the "custom" JBL's daily! The son was not much into music. "How much for the speakers?" I asked. "Well, considering I was just going to throw them out......could you possibly pay $100?? Of course I did not hesitate. Also included were a pair of LE5-2 drivers, LE20 drivers, and NOS LX2 crossovers! And BTW, he said most of the speakers he hauled to the dump were JBL's!
Here are my components:
15" LE15A woofers, 8 ohms, recently re-coned and restored @ The Speaker Exchange, Tampa, Fl
LE85 mid-horn drivers, wax seals intact, 8 ohms
H91 horns
L91 lenses
077 slot/prism tweeters, blue diaphragms, 8 ohms
LX5 crossover
N8000 crossover
Cabinet dimensions are approximately 45"high x 20"wide x 19"deep
Q #1: What do I really have at the end of the day? What can I compare them to? C50 S8?? 4333??
Q #2: How do I internally connect all of this? Currently, a speaker cable would connect to an independent spring terminal cup with 2 fuses and not the spring loaded terminals on the LX5 crossovers. I want to install a new jack plate and use binding posts for use with banana plugs. I also want to eliminate the fuses. The confusing part is rewiring and bi-passing the fuses. I can't figure out how to do this. Can someone do a simple diagram of the wiring based on my components? Or point me to a link that might have similar schematics.
Thank you in advance! Geno
