First of all you are using the wrong crossover to the tweeter. I believe. JBL made a much. higher frequency crossover for the ring radiators. Some where close to 7000 hz. If it were me as I don't like the early 075's I would want a cross some where about 9 kHz that we used when tri-amping larger JBL entertainment systems. I thought as best as I can remember that the 2405 was a much better driver. Depending on which horn you are using you might want to try 800 hz crossover freq to prevent cone breakup by the D130. Its not a midrange speaker. Only the very latest 15" JBL woofers can work above 700 hz or so and maintain less than 2% distortion. Yes musicians operate the D130 full range for Guitars. They like that distorted sound.
The n1200 is the correct crossover for the D130 and LE175 . I’m looking to add the 075 as the 175 isn’t a true tweeter and I’m looking to get more high range. Looks like there are a couple of options for crossovers to do this , I just don’t know exactly how you wire the two crossovers to the drivers with one input . I’m currently running the D130’s in Altec A7 VOT cabinets and the 175 with 511b Altec horns . The combination sounds fantastic , just looking to expand the range.
I have a similar question. Although I have LE14A instead of the D130, but I want to expand the upper end as well. Since the LE175 poops out after 15k (I'd imagine it starts rolling off well before that, but have nothing to base that on) I'd like to give it some help from around 8k or so on up.
I'm wondering what you decided to do because I'm very new to the complexities of crossovers and I'm unsure how to cross the LE14A, LE175, and ST.
Maybe we can work together to figure this out.

No, The D130 was not to used with the LE175. It was the 130A that was to used with the LE175 and the D130 was used with the 075 with a 2,500 Hz crossover.
My suggestion would be to use the N1200 crossover but put an L-pad on the output and tie the LE175 to that. The three provided positions on the N1200 are not sufficient.
Then put a 1 or 1.5 mfd cap to an 8 ohm l-pad on horn circuit (before the horn L-pad) and tie the 075 to that.
