Megaton A9090 + DE25

Or, preferably the DDS ENG 1-90 Pro + B&C DE250, although several people have had success using BMS drivers and others.

These are both 90 degree waveguides btw. EQ is needed, whether active or passive.

I'd be using a DEQX for PEQ and crossover duties. (May be replaced by a Dolby Lake at some future date.)

I wonder, is it possible to convert dome tweeter into compression driver by building small chamber in front of tweeter's dome.

Australia has a small market and the small amount of sellers work on margin rather than volume.

On another note, i spotted another Chinese compression driver, and traced its manufacturer website which(finally) has a graph. For $65AUD this looks like a very nice driver if the graph holds true +- 3Db.

You could if the dome was concave. Otherwise it gets difficult.
