Driver match for 2x Beta 15a

[batsong]

What full range driver would you match with two Eminence Beta 15a's in a large open baffle?
2a3's or 45's on the upper range and EL34's on the bass.

Just now realizing that I put this in the wrong section...should be in 'multi-way'.

I believe Martin King did some work on a large open baffle using
2 15's on each baffle. it might be good to look at that first.
