I bought 4 of these nice drivers that were on sale, And now I need something to put them in, I had originally planned on doing the Dayton 8 , But I already have some MTM speakers, and I'd love to have a shot at making a highish efficiency TMM 2.5 way physically time aligned speaker (something like the Auriga but with 1/4 the cost drivers). Of course this would be only my third speaker-building project, and my first to do any design on myself. 
I would guess that I could steal some design from the Dayton 8 plan. Cut the box and port size in 1/2 for lower ported speaker, And a sealed box size of about 1/2 cu FT seems ok for the other 8”.
But how do I find out the angles for phase alignment, and even more importantly, how do I setup the crossovers, I would guess that I could steal part of the low/high crossover from the Dayton 8 plan, and I would just need to come up with something for the sealed part of the 2.5 way, but of course I’m probably way off base,.
Could someone set me straight?😕 Either point me in the right direction, or smack me and turn me right back around.
