So... I'm building 2 x Mid/top box with 2 cones, Infinite Baffle. and would like to know the audiophile theory. I appreciate that having 2 vertical mounted cones for mid already has comb filter problems, although these appear to be minimal.

main questions are to do with each cone having its own chamber, or all sharing a common chamber, and what effect does larger and smaller chambers have on mid? Also, does porting have any tonal effects on mid, or is just for bass driver control.
bass box stuff seems to be irrelevent, but i do have access to clio, for measuring, when they're done.
ps this is a personal project, not work.

Why two?If you cross them low to tweeter enough the comb filtering wont occur.
Sharing a chamber is fine,but two smaller chambers might have resonances that are higher in frequency.
Yes porting can have effects on the mid,port resonances that dont appear on t/s modeling (1/4wave tline resonances etc)
Consider non parallel wall enclosure,alot of the energy reflects back out the cone from inside the box.
