My first post and I know little so hope this is correct venue. I acquired some older JBL parts and c53 Libra cabs. I have a pair of LE14A and a pair of LE14C speakers. I have a pair of LX2 (one is an LX2-1) which I believe is correct for the LE14C. I also have a pair each of N1200 crossovers and LX10 crossovers. I also have LE175DLH horns - LE175 driver + 1217-1290 horn.

I'm surmising the best combination would be the LE14A w/ the horns and correct crossover over the simpler LE14C + LX2 combination? I would appreciate any input in this regard.

If I go with the LE14A + LE175DBL the specified crossover seems to be the LX10 which is at 1500hz. The N1200 crosses at 1200 and appears to be a more sophisticated unit. The marketplace seems to determine higher resale for the N1200 which leads me to conclude it is a superior unit? I would appreciate any input from those who know in this regard.

Of course all speakers need refoaming even after brake fluid treatement, though that did help.

Much thanks.

Hi
The period correct crossover for the LE14A & LE175DHL drivers is the LX10.
What you end up with is the S1 system.
Here are the links to the S1 system and the LX10 network:

The N1200 is designed for the 130A woofer and may not work as well with the LE14A.
