I'm starting to plan 4333a project armed with a brand new copy of the Newell/Holland book. Been reading about diffracted wavefronts. Any opinions on the box design and how they could be improved are welcome.

PS. 2405, 2420 and 2231 all original alnico. I will have them tested and re-charged if need. New dia and a recone on the 2231. The xovers will go to the Doctors for a check up too !
