I did start a post to suggest that your xo frequency was too low, but decided not to proceed with it as you'd already bought the crossover and I didn't want to complicate matters!
3kHz is also uncomfortably close to 2kHz which is the bottom of the useable operating range of the tweeter.
I suggest you do not cross over lower then about 5kHz (12dB/octave) with this particular tweeter.
And now data...
Using REW and Dayton IMM6 calibrated microphone.
I ran sweeps on three speakers:
Klipsch RC25 Center
M1 - my first build. 2x2 XPS panel with a single Dayton ultra exciter, 20w
M2 - second iteration, different panel geometry, two Dayton exciters, 1 ultra 20W, 1 mega bass 40W
This speaker also has a Dayton planar tweeter. I cut the crossover out and tested the main panel and tweeter independently using 0-20,000 sweep on the main panel and 3,000-20,000 on the tweeter.
What I see:
Note: measurements were made at different times, M1 and Center were measured from the listening position. M2 was measured at center height 1 meter away. All speakers pick up around 80hz and drop-off at 10,000. Response between 80 and 10k is ~flat. At 15k SPL is 70% of baseline, at 17.5kz 60%. M1 and M2 are much less flat between 80 and 10k but rise and fall the same as the Klipsch at the boundaries.
So what's going on? My purpose in making the M2 with planar tweeter was to improve high end response above 10k. But the (presumably better engineered) Klipsch center speaker does not perform better. Two possibilities, room acoustics, equipment setup. I am using a Yamaha RXV585 amp. Test were done in Straight mode to bypass internal processing. I'm leaning towards room acoustics.
The room is irregular shaped. Let me try to describe it. The listening area (tv room) is 18 wide by 15 deep, with a 12 ft ceiling. Behind that is kitchen and dining room, wider to the left and right with a 9 foot ceiling.
Ya'll with me?
What do you think is going on? Do I have any options? I've read up on bass treatment but not found a good resource for high frequency

Your goal was to build something that approximated Electrostats. Electrostats don't measure flat. Do you like how the system sounds? If so, you have your speakers.
