Interesting.

Is this a prototype or a model intended for regular production? General dimensions? Obligatory question of price?
Any more details on the new driver? I wonder if the bigger driver lets you run the mid and tweeter closer to wide open in regards to the crossover; 2x8 + mid x1 + tweeter x1 didn't work because the 8" driver was too efficient, but maybe the 10" gets close to the 2x8 in output with less sensitivity to better match the mid and tweeter?
The sealed crossover enclosure sounds like a great idea not just from a performance perspective but from the logistical one you brought up as far as field repair and upgrade.

Is this a design feature that will be reengineered into the other models? Being able to put a "good" crossover into a speaker to hit a price point and still deliver a great product with the possibility of being able to later have a customer installable field upgrade to take things up a notch as budget allows sounds like an interesting prospect? Regardless of all that, easily field serviceable parts without having to box and ship speakers around is always a good thing!
Interesting that the debut model with the 10" woofer shares a similar driver layout to the Pan/Muse. Did this just happen to work out this way, or is this driver configuration developing to uncover yet untapped potential in the general design?
(and I've been digging the speakers I've seen photos of as of late with the walnut showing some aggressive lighter heartwood character.

I did a project in woodshop class forever ago that I used a crazy piece of cherry that was almost maple blonde throughout save for some wild flowing looking patterns of traditional cherry wood color.)
