hi all.. "first" post here.
actually, i did briefly participate some years ago, but have no idea what name i used then in order to re-register with the same name.
my question is regarding the phase correct wiring between an N400 crossover, a 150-4C and a 375 fitted with a 2397 horn (if that makes any difference). i am unsure of the relationship between the terminal connections on the N400 and the red and black terminals of the drivers.
can someone detail the way these 3 components should be wired to ensure absolute phase correctness?
thanks so much!
ps. if anyone is interested, my 150-4C's are loaded in piano black C40 Harkness boxes. i took the 375's out of the C40's, removed the 90 degree horns that were originally installed and now have them on top with the much better sounding 2397 horns. it's my understanding that finding a pair of C40's with 150-4C's and 375's is pretty unusual. a few years ago forumite Oldmics helped me obtain a correct replacement 2440 diaphragm for one of my 375's which came to me in blown condition. i suppose i should replace the other diaphragm in the other driver too, but i can't bring myself to break the wax seals!
