I recently got an old pair of LX2 xovers- any info anyone has on them would be appreciated. For ex.- polarity issues-
The in terminals are marked B & R-?
The Lf out is marked 1 & 2, The Hf out marked 3 & 4. There is also the mystery knob in the center marked 6000,3000,or 1500. Thanks in advance for any info!

Mystery knob is crossover frequency on that model, I believe.

There's a separate attenuation knob....

It has been brought to my attention that there are several versions of the LX2 crossover. Here's schematics.
