Hello,

Bought a second set of what I think are JBL 4312a Control Monitor Crossovers but not sure the item was properly marked. I figured if I was going to attempt my first ever hands-on upgrade of a crossover network that I should do them on a second set...in case I totally mess it up.

Please take a look at the images and let me know if these are the proper crossovers for these speakers. Your expertise is much appreciated!
