Default Advice on drivers for dipole speakers

I'm planning a compact 3-way dipole speaker.
The bass section is provided by LX521 which I have.
The mid driver is Seas M15CH002, I have a pair from a previous build.
I'm considering the following for the high-mid/tweeter range:
Tectonic Elements TEBM35C10-4
Dayton PC68-8
Scanspeak 5F/8422T01
BG Neo3-PDR

Edit: I'm open to considering any other small drivers with 10w+ power rating.

Crossover somewhere around 1-2khz, at least 24db/oct.
The mid and hi drivers will have no baffle at all.

The system SPL is already severely limited by the M15 driver so no worries about the 10W power rating for some of the tweeters.

Do you think this setup will work?
Which hi driver would you use?

I second that. I have a Neo-3 (not PDR) with the back removed and it sounds amazing.

How important do you think rear radiation is for the HF? Some say yay, some nay, some yay then nay then yay (Linkwitz )

a single 5" nude driver will not go low enough to meet the bass section
that is why most people go 4 way

viable 3 way options:
-6" MTM with Neo3
-with the full range drivers you listed, you may use a 8" mid and cross around 800hz

No, but that's not (quite) what I'm asking. It's obvious you think it's important, so perhaps my question to you (and DougL for that matter) specifically would be; why? My initial question was to the universe at large.

Well Matt, if you want to hear the universe laugh, ask a universal question
