millercarbon,
I did some rough calculations on my electrostatic diaphragm. It is 6 microns thick, 5.25" wide and 48" tall, with a total volume of 1 cubic cm. Assume the specific gravity is 2, and I get a mass of 2 gram, which covers the freq range of about 50 Hz to 20 kHz. So the total low mass of 2 gram for the stock tweeters in a single array and 4 gram for the tweeters in the double array, make the low mass arrays very competitive. Then the question is, how well is the low mass tweeter diaphragm controlled, compared to electrostatic and ribbon designs? I wonder what the Be tweeter mass is, compared to the stock.
klh007 already mentioned a few speakers that may be superior to the stock Moab from 100 Hz up. Eric should send a full Be Moab for a shootout test between this Be Moab and any speaker at any price. At $14K for the Be Moab, that is still cheap compared to all the big name flagship speakers out there. Even take Focal with its Be tweeter. The Grand Utopias are crazy expensive, and even the middle level Sopras are way over $14K.
The video of the piano played with and without the isolators is meaningless. The left piano with the isolators looks like it is near the wall, and the right piano without the isolators appears away from the wall. The bass notes of the piano are on the left. I heard a more boomy sound from the left piano. The entire range of the right piano sounded tighter and more tinkly in the higher notes. This correlates with the placement of the pianos and room acoustics. I can't draw any conclusions about what effect the isolation has.
