None of these!

All of the pro drivers from these companies (as far as the models that I am aware of here in the US) have Qts that is too low and Fs too high for open baffle use. Look for drivers with Qts of 0.5 or higher. The exception would be if you can connect them to an amplifier with controlled output impedance, and set that to some "high" value (e.g. 8+ ohms) to cause Qts to increase.

Have you seen the studies of open baffle speakers by Martin King?
http://www.quarter-wave.com/OBs/U_and_H_Frames.pdf

He uses Eminence drivers (Alpha 15) with Qts > 1.0 with very nice results. Can you get those in your country?

Perhaps:

EMINENCE DELTALITE II 2515 - Thomann UK Cyberstore

Another suggestion:

AE Speakers --- Superb Quality, Unforgettable Performance, Definitely.
