This bit has been bothering me... is there a reason EV would specify that it "must" be mounted this way? Further, is there a specific advantage to be gained from the Dietz design by mounting the speaker from the rear? Or are we just looking at something as simple as personal preference?
I don't think it's preference. I think the EV plans require it to be mounted from the front to maintain the proper volume. This would explain why on the Dietz (where it is mounted from the rear), the baffle is moved forward 3/4" (the thickness of the baffle).
Good reasons to mount it from the front:
1. You can be a little sloppier when cutting the hole (I used a circle guide for my router and it's still a bit wonky - this is not trivial).
2. You can actually attach the baffle to the carcase with glue (if you mount from the rear, you are forced to use only screws [and weatherstripping tape] since you would not be able to get the speaker in otherwise). NOTE: The clamping setup to glue the baffle in is kind of a bitch. I just used screws and figured I'd glue it in later on some rainy afternoon.
3. T-nuts and machine screws are a lot easier to deal with when something shits the bed right before a show than bolts (in my opinion).
Good reasons to mount it from the rear:
1. The speaker is more protected.
2. You don't have to buy as much grill material since you can just sandwich it between the speaker and the baffle. And it's easier to install.
3. It looks cleaner, though far less tough.
Here's a miniature PDF file with the plans:

And even though you're not going to spend much time downloading it, perhaps you'd enjoy more music?

Anyhoo, here's what my finished cabinets looked like. Please ignore the clutter (and the original Dietz off to the side).
I installed two more grill offsets after this picture was taken to further protect the speaker from van damage.
