The front baffle board, basically the front face. The sound is going to come out in 180 degree concentric rings so you are better off with a small front surface (for the high end). With a small face, the concentric rings will be smaller, because they will “bend back” around the speaker once they reach the edges.

E.g. a tweeter in small 15” angled box is going to work better than one mounted in a huge 24’ x 36” rectangle box.

There are threads on this site that can give you insight about determining the size and shape of the surface upon which the tweeter will be mounted. It plays into the choice of crossover point too. Might want to search for "baffle edge diffraction" and "baffle step frequency".

I'm tri-amping these speakers. Would it be better to build separate boxes for each or just do larger at the bottom and smaller on top?

Yeah I'm just grasping an understanding of this stuff. Been reading all kinds of things, some contradicting others but I guess it all boils down to what your use will be.
