I think you might want some bracing in there, but lets ask the expert!
Thanks Nick - I'll be adding some bracing, haven't thought much about the details yet - maybe just simple midpoint stick/dowel braces front-to-back, side-to-side?

Thanks tux - already thinking ahead to how I'll get one of these up on top of a ladder in the back yard for measurements.

I have a Speaker newbie question; What are the main considerations when deciding to go ported or sealed ...?
Thanks Craig - the main consideration for me was extension (see WinISD graph earlier in the thread, comparing -3 dB point for sealed vs. ported). I decided that I'd like to be able to run them a bit lower, to do a crossover to sub at 60 Hz - not sure that I'll run them like that, as I'm currently crossing my mains at 100 Hz, but I didn't want the design to prevent it, especially since they have 15s in them. Ported also means bigger boxes, and a few more variables to juggle (box size, tuning, port velocity / resonance, excursion below tuning). I'm a relative noob too, others more experienced in speaker design might chime in with other factors that I've left out.
I guess I also wanted a little more challenge / learning experience, and since its DIY, to build something a little different.
