Since everyone else seems to be asking Lars Risbo for the transducers they want for Christmas, I'd like to know if there are any plans for midrange drivers with higher efficiency, more in the range of PA.

4 inch midrange - Blisema 3" dome
Tweeter - T25
Why not just move the midrange corner down a bit? The Bliesma midrange seems suited to a 400-500Hz transition, depending on the particular x-over and SPL target.

Cut this out as there is no need/sense for that in such design and You'll end up with what i said before.

The textreme has an advantage of lesser 2nd order harmonics - compared to getting the purifi to 400 - 500 hz.

Wow! You're leaving a lot of critical music out with that lineup! Add a super tweeter and at least a 12" and 15". I think you'll be missing the range in which feeling and intuition live, which is so crucial to the music.
imho, ymmv

Hmm... apparently IMD and THD is meaningless. So many ways to look at it:
