Crossover JBL LE14A, LE175, ?? tweeter.

Uh what??

After copious amounts of reading, I still need some direction.
I scored a freebie of 2, JBL LE14A, 2, JBL LE175 with H91 horns, and 2 JBL LX10 dividing network.
The LE14A is a good driver as is the LE175, but it's pretty lacking over 12k, and doesn't produce anything over 15k.
I'm not sure how to fill out the top end frequencies. I guess I have a couple of options. I can rebuild the LX10, build a box and run it as it had been used for 60+ years, or I can build a 3 way crossover, add a tweeter to fill in the top end, and then run it. I'm hoping to do the latter, but I'm not sure where to cross everything over? 800 and 6k? 1000 and 8k? I'm just not sure what is ideal, if anything.
Some help from some of you more experienced guys and gals would be great to help me see this project through.

Hello Uh what, another crossover that works with those components is the lx80. This crossover is a 800hz model. Adding a 2405/077 the same driver or a 2404H will get you the top end you are looking for. If you only need the bandwidth out to15Khz look for the 2404H1 which can be had cheap. Just make sure it does not have a aftermarket diaphragm. You can find on line the diagram for the N8000/3106 crossover a 8000Khz point. I have used with those components 800/8000 as the crossover points
 
Build the 3106/N8000 and try it with your LX10 first. You might like it. The 800hz crossover point used the longer H92/2312 horn

I'm so sorry I didn't see your responses for 3 years. I can't seem to find a schematic for the N8000, I can only find one for the N7000. So here's what I've come up with.
The HF section is the top half of the N7000, the LF and Mid section is based on a crossover designed by Jack Gifford for woofers that are less than 95db sensitivity.
Can you see anything inherently wrong with this?
