AM6212/00 crossover topology recognized by forum member Guido nearly a year ago as potential 4430 enhancement drives 2431H on PT waveguides. Two units on pink noise at ~1M shown on RTA in averaged mode, I suspected one was "hotter" than the other, but I don't know yet if it's the horn or the driver.
Scale is 2.5 dB per dotted line. They shouldn't let us have measurement devices like DEQ2496, probably. Too easy to see what's goin' on with stuff, like manufacturing variability and defective units.
How much of this is room response? How do I get more "anechoic," move up to like 6"?
I think I know what I'm doin' next -- another one of these....
