The frame is unlikely to get any smaller -- not without moving to a (lessor) cast or stamped metal basket

Its a new frame tho, right? well, here's hoping, but it looks the same size. The gen 2 driver had a highish Fo/Fs, have a hunch the new one might be significantly lower, around 60 hz

The new frame is the same size, it is just stronger & stiffer,

Another point on the subject... i believe the A7 has a more advanced alloy in the cone... certainly it has a lot smoother surface (something you appreciate when putting thousands of spots on the drivers.
