I'm not as convinced as some of the others that the high ceiling is a main contributor to the problem. If the relevant specs of the speaker (89 db/1W/1m efficiency; 6 ohm average impedance; 300W max "music power" capability) are reasonably accurate, they should be able to generate peak SPL's of around 105 db at a listening distance of say 4 meters (about 13 feet), even in an infinitely large space. And I wouldn't expect reflections off of the ceiling to be major factors either at most frequencies, given the lengthy delay in the arrival of those reflections relative to the direct sound arrivals, and also the attenuation that would occur along the way. Certainly wall reflections could be significant factors, though.
Some questions:
1)When you refer to having both A51 and JC1 amplifiers, are you biamping the VR4Jrs with them?
2)If so, what outputs of the 8802 are you connecting to each of them? If you are by any chance connecting RCA outputs of the 8802 to one and XLR outputs of the 8802 to the other, that might result in a 6 db volume differential between the two sections of the speaker, even though the two amps have identical gain specs.
3)When you say "I have 400wpc running at 70%+ at the moment," how do you know that the amp is running at 70%+?
4)Can you describe the positions of the speakers relative to the nearest walls, and the location of the listening position relative to the speakers and to the nearest walls.
