A 1" driver will reduce the cost a lot, only problem poor mid response there are nice ones that do 800Hz.
Like the popular 1" DE250 $128,-
http://www.parts-express.com/pe/show...number=294-605

Here a nice horn for 1" $200,-
AutoTech Iwata-600 - Horns DIY Sound Group

Will look good with 15" woofer about the same with.

Then one speaker would cost $513,- drivers and a horn for 2 way.

I think that the 2" fatialpro offers very good low response usable down to 500Hz with a 24dB filter. For hifi low power amp input a second order filter will also do. Will make a great precise midrange response.
Faital Pro HF204 - Faital Pro HF204 2" neodymium high frequency compression driver with a ketone polymer diaphragm. Faital Pro HF204 HF drivers available here at US Speaker.

This to gather with the 15WS600 woofer a 97dB system 28Hz-20000Hz XO 500Hz. And the state of the art JMLC 2" horn. Point source 500-20000Hz
For $605,- 2"driver fatialpro, jmlc400, and jbl selenium 15W600.

Mid-response of the 15WS600.

if you do that, wouldn't its own acostic-roll-off cause it to roll off earlier...and maybe even faster than 24db
which 'could' lead to phase ....

This is right, then you can filter the woofer steeper so you can match the phase with the horn driver works also fine with my own loudspeaker.
With the steep fillter the woofer can not mess up the clear tight midrange of the HF-driver. A win win situation isn't that great.

Then you are well on the road to enlightenment. Good for you.

Whatever drivers and horns you chose to use, measure, listen, tweak, measure, listen tweak, etc, etc. It can take a long time.
What works for me may not work for someone else, but we can give advice. For example: Bear likes the horns turned on their sides, I do not. I like a Bessel 4th order acoustic slope for my crossovers, some people don't. You'll have to find what works best for you.

You know that if you go SS amp and use the miniDSP on the 18", you could keep it open baffle. You might like that with the horns.

A other advantage of a 2" driver to a 1" is the shorter horn.
This is desirable to prevent any horn coloration of the response.
