Still a long way until I can have an opinion. One thing is sure - after two days of moving them, taken measurements and a few listening sessions there is something permanent on them - an easiness and proper integration of the treble in the whole spectrum that bewitches us. They are faster than the SoundLabs and do not suffer from the problem that Andromedaaudio referred - sounding slow because of the bass.
Still dealing with the suckouts and peaks bellow the Schroeder frequency - I have put in place again the lateral Flutterfree panels for the preliminary tests. Moving the speakers and listening position I found I can get response down to 19 Hz - but with a suckout around 55Hz.
Listening this morning I found I have already had them in a better position - but I am not sure anymore where they were positioned at that best spot. Next week I will start a more systematic approach to setup, using also the CARA software - simulation is less violent that moving these 160 Kg objects and sometimes more rewarding!
