N-1201 is an "off the shelf" Altec component, it's a clone of the model 19 crossover. It was used in some factory systems, but was also available as a stand alone component. It's one of the most versatile XO's Altec made, and the only passive i'd use for tangerine equipped drivers.
The woofers are some version of 416, since he says "ALNIKO" and it has a 16 inch frame we can assume it's a 416-8B which would be the most desirable. But, we can't be sure of anything without seeing it. Model 14's woofer is a 12 incher in a 13 inch frame with a rolled edge and mud magnet, and it's crossover is entirely proprietary to the 14 and 9842 studio monitor.
