Ok, among other stuff, I have 8 drivers by DS18, the model is the 12-ME (supposedly 30Hz - 1,000Hz, 600 watt RMS). Could/should I use two of them in this box, tuning one as a sub and the other as a mid? Or would you suggest using them as subs and choosing something else for mids? I could adjust the design to include two 6" drivers. I have enough Audiobahn ADM 60Q's (100 watts RMS, 30Hz - 5,000Hz) to pair with those DS18's? If I use the 6" drivers, should I put a baffle between them and might they need to be ported?

As best I can tell (height measurement is blurred) the external dimensions are 32" x 17.5" x 16". I'd like to reduce the height to 28", I have a lot more panels this height but if the 32" is required, that's fine. I'll adjust the depth based on the cubic foot requirements. Is there another design that is less rough or more appropriate for the drivers mentioned? I've been looking and haven't seen another three way design with the recessed sub, although it's not a requirement, it's what caught my eye, do you know of a proven design that's similarly constructed?

To be fair, the design looks a bit rough and depending on what dimensions you can live with, another 6th order band pass can also fit the bill as it's basically just a bass cabinet within a mid top.
You could make the outer baffle, sides and rear 28", then put the lower and upper panel on top of that to get to 28" + 2 x panel thickness for total height.

Are you able to securely glue the laminates? If not, use them on the outside, a good loudspeaker cabinet is glued and screwed (or stapled), If the glue and screws give a structural bond that's air tight, I see no benefit in (also) using battens in the corners but feel free to use any.
My panels are 3/4" plywood with simulated wood grain with one side laminated (OSL)
