Yeah, I have the board on the right/lower, but not the other board. I never would have guessed without your help, and would have had a devil of a time figuring out why my swap didn't work.

Okay AL-4's, but it appears that I am missing the second part - the board with the transformers. I'll talk to the seller, to see if he has the other parts.

LOL, I never thought that they would be LS2 parts! I'm new to Klipsch, but I do understand that LS2s have different drivers and cabinets, and I have not seen anybody recommend this combination.

Another view:

Hi, new guy here. I just bought a pair of La Scalas from 1978. They came with some crossovers and extra parts. I can't figure out who made these. Shows a P/N 11646 on the board, and there is a panel to bi-wire(?) the input connections. I'm hoping to figure out what I have, how to install them, and how to tweak the sound. The crossovers that are installed right now are the original AA parts, and the drivers have been upgraded as well, I have not tried to figure out those changes yet.
