Klipsch RP-260f xo upgrade or correction

Hello everyone

I would like to upgrade the xo in my front speakers Klipsch RP 260f to correct a dip between 1kHz and 2kHz in the frequency response (see in room measurements). I think this dip is causing room correction using anthem ARC (genesis) to bring the whole frequency down in an attempt to flatten the curve. As a result the dynamics are lacking when ARC is on. I hope I'm describing it correctly here.

I have no experience in xo design or software, hence I'm asking for help.

Attached are pictures of the xo, schematic sketch (borrowed from Klipsch forum) and arc measurement file.

RP-260f is two way, tw and 2 woofers, I can see that GR research corrected this on a different model RP-8000f by designing a 3 way crossover (2.5 way) to correct the dip as well as the RP600M

Klipsch RP-600M Upgrade

I doubt that replacing XO components with same values and better parts would correct it.

I build my own amps but have no experience in XO design. Any suggestions from experts in this forum would be highly appreciated.

Thanks in advance

If there are no reflections visible in the impulse response within 5 ms then 5 ms is right. Yes 1 meter distance and mic pointed at the speaker are good, at a height somewhere between the mids and tweeter.
 
Update

I calibrated the mic, adjusted the levels and attached is the acoustic timing reference measurements.

There is a dip in the mid range frequency about 10dp and tweeter level is higher than the other drivers

You will need to learn how to take accurate measurements for crossover design. There are some stickies at the top of this section of the forum that are well worth reading. If you can get accurate measurements, and upload the files. I'm sure a few people would be more than happy to simulate a crossover for you.

If it sounds like too much hassle, you'd be better off selling them.
