I would also add EV and dB Tech speakers into your choices. Both make some excellent cabinets and you can pick some up 2nd hand for a bargain.
But of course, sound is always a very personal and subjective issue. You really can't beat having a proper live demo. When you're spending a considerable amount it's worth the time and effort to visit your local dealer or even take a road trip round a few dealers and have a good listen to as many different speakers and brands as you can.
