Hearing few line arrays, has me on a pet project.

Obviously LA's have dedicated custom drivers, but considering diy option with multiple 1" drivers per mid, to achieve exceptional 13.6k+.

Suggestions, opinions, makes, models.

Before you throw ££ at supposed high end stuff listen to Beyma CD10.

BMS 4540ND or 4538. Beyma CD10 (Fe and Nd) is also a very good hint! If you want to spend that sort of money, 18sound NSD1095 is the best super HF i have heard...

How do you plan to couple the drivers? A wave guide, or just standard horns? What you use is just, if not more important than the drivers!

you could just go with BMS 4505 as this is possibly the best off the shelf line source waveformer+driver.

What would you suggest?

Tried twin 1" to 2" adaptor, was not impressed with results.
Was thinking 1x driver per horn, arrayed vertically.

Like the sound of BMS 4524, but not sure if that would provide sufficient SPL.

My top contenders where B&C DE25 or DE250, on B&C ME45 horns.

Was told Celestion 9040 1" horns, sound decent with many 1" drivers.

Part of the reason arrays can sound good is due to the use of the high number of compression drivers. Compression drivers generate significantly more distortion at higher power than at low power (typically a factor 10 more going from 1W to 10W).
If you can produce the required SPL with 10 drivers pushing 1 Watt of electrical power versus 1 driver pushing 10 watts, the difference in sound quality can be significant.

But as is the case with everything, there is never a free lunch.
Arraying multiple drivers required extreme attention to prevent comb-filtering. If you simply stack multiple drivers on conventional horns together it is very likely the results will not be better than when you would just have used 1 driver on a proper horn (and when i say proper i mean one without diffraction throat).

Like Corell said, the BMS 4505 is a perfect driver, with the waveguide attached directly to the ring radiator diaphragm itself. 
Best regards,
Teun.

And then find how much more it takes than that to make an array that works…
