All info JBL is on the Lansing-Heritage website:

This link takes you to the forums. The Search should help you in the Tech Info section on the Libras. Here is one link with a pic:

They Libra also had the C53 designation, so use that as a search term. The L14C is a full range driver in it IIRC -- but I think you can add a tweeter (LE-20) to the Libra cab -- note the block-over plate in the photo. The full range driver has the Lansaloy (sp?) rubber-like surround that can harden and crack over time. Do not let that keep you from buying the Libra -- driver can be re-edged with foam. Here's a link to info on that driver:

Here's a copy of original driver info on the Libra (1968 vintage) from a post by Zilch on L-H. He is one of the masters on there (also AK member):
"C53 Libra, from the 1968 catalog:
23-1/2" x 14" x 11-3/4" deep. "Especially popular with the LE14C."
Recommended loads there:
1. LE14C
2. S11 - LE10A, LE20, LX11
3. S12 - LE14A, LE20, LX8"
L200B power requirement? 100 -- 200 SS wpc. Again, LOTS of info on it on the L-H site: at least I've found 8 pages on my L200s. I'm going to put my Carver M-1.5 on my L200 (first version, different woofer & crossover than your later version). It's 350 wpc. I have to put new binding posts on mine (still!!). No extra time from my job these days.
Be respectful of the parts in the L200B -- they're not just laying around. Crossover parts and horn diaphragms are available, but are pricey.
You are going to enjoy the hell out of these speakers. I'd buy the Libras too if the price were right.
I'm sure more AK JBLers will chime in with more info.
