i agree with you,
my first idea was simply to replace the actual tweeter, that is not an original yamaha JA0505 as it should be, you know these 50 year old things, the present tweeter is a Phillips AD0160/T8, for which i found an experimental curve like this:
so this means that this phillips tweeter gives up at 18.000Hz, and the sensitivity is aorund 92dB, and not very flat neither
once this is said my alternatives would be:
1- to use the yamaha JA0506 it as a supertweeter keeping the phillips, and then where to cut the supertweeter frec. 8000Hz. ? more ?
2- or get rid of the phillips and put this yamaha JA0506 tweeter in its place, in this case i will be using the existing crossover with its high pass filter at 6000Hz and adding an L-Pad attenuator to attenuate from the 115dB given by the tweeter and accomodate to the rest of the speaker´s setup (woofer and squawker)
should this be better ?
thank you
