In mine (clone cabs with 416-8C, 800-series HF's with GPA 8-ohm alum dia's) I got a lot better-balanced frequency response with the N1201-8A networks than with the N-800 8-ohm jobs. I think it's a good match for the smaller, bent HF horn. The bass comes off much stronger relative to the 1200hz x-over point than at 800, not to mention whatever other wizardry the n1201 does (aka the Model 19 crossover).
