No special considerations - it is just a vented box. Calculate the volume and port pretty much as usual.

The close proximity of all the drivers may add a bit of loading, so tuning a bit lower to start out could be a good idea, but it depends on what electronics and crossover frequencies you are using and how the response turns out.

No, per the shading on the drawing it shows a solid back and open front, creating a 1/4WL vent pipe, and why its depth/area is key to its HF response, etc.. It's a design I've 'cloned' and it works quite well, just didn't know EV called it a manifold. It would be interesting to tweak the design to incorporate a Karlson coupler to increase its HF response high enough to XO to a mid horn.
