And 2500w to two of these is low balling them a bit. I push 3600 to a pair (QW-218) and they rock the house. Headroom is everything in the sub world, keeps them from tearing themselves apart, especially in the environment you are planning on using them in.
Two coupled together in a bin can be slightly more efficient than two separate bins pushed together, but not really an audible difference by most humans. It depends upon your space available and room acoustics (is the room long enough to allow a low freq signal to properly propagate?).
If the room is strangely shaped or shallow, you might be better off with a few singles strategically placed than two pair throwing from only two single points in the room.
Let us know what your room and/or dance floor consists of and we can go from there.

And for sure, if fiscal restraints are in place, you gotta start somewhere - been there, done that. Work with what you can and then get what you you really need when you can.
I pushed 14,400 watts into four VR-218s, (8 Low Max speakers), in a gym Saturday night and it didn't seem enough with 700 c razed teenagers screaming, but the venue management was happy, so okey-dokey.
To answer your question about "best boxes", the QW series boxes are engineered specifically for those drivers. If you are planning to replicate them through outstanding craftsmanship and woodworking, I salute you. I am not a woodworker and I would more than chew up the cost in Baltic Birch raw materials and "do-overs" in the structural support arena.
Best of luck,
How did you go with your 4 x 18" Low Riders? Iv'e bought 4 and plan to run them in small single driver, ported boxes around 145ltr, according to the Peavey spec sheet that came with the drivers.
Will be powering them with a single IPR3000
