Great releases, thanks for inform.
The 15'' despite having a heaviest cone will be a great option to the Eminences.

Worth waiting for some real-world measurements to see if that 97dB sensitivity rating is realistic.
Also, the top-end extension and smoothness seem a bit too optimistic in their graphs

Well the T/S parameters say 93.
The 15 has much higher Xmax than the 12...

Here's a review of the 15-inch version:

I would like to use this 15" Bianco with their new 8" FR Driver on a modest baffle, perhaps 24" x 30".  Supported by a sub of course.. I think I know enough to figure out where and how to do the cross over.  But perhaps not enough to know if it is a good idea.  I currently listen to the original Hestias but only the mid and tweet, the bass being handles by a sub.  Goal is an approachable OB for the average Joe while upping the SQ of the Hestias which is already pretty good, at least to my ears.
