Paul, did you search the forum before you opened this thread. 😉
I had a quick look and found at least 4 other threads with the same topic...

Pinkmouse,
I have searched and haven't found anything on this forum close to suggesting how I might build the top curve on my box. If you have seen any threads which deal with getting a very accurate compound curve, then I would certainly like to see them. I have not seen this addressed on the forum so far.
Fair enough Paul, though I think Rob Wells had compound curves on the tops of his translam speakers, so that might be worth a search...
I have changed the thread title a little to help people searching for the same info.
Good luck with your system 🙂

Paul,
Wood will make that top curve, no problem. Think of curved chair seats, stringed instruments, etc.
Probably the easiest way would be to start with flat top or just the front peak curve. Then use auto body filler. Sculpt whatever curvature shape is desired while it is still clay-like and sand it to the perfect shape once dry.

I'm not familiar with builders bog. I was thinking of Bondo or an epoxy that is thick enough to form a clay-like mixture, so it is easily shaped but retains it's form while curing.
I think MDF of any thicknesswon't work as well as plywood. The actual construction of this box is quite simple; any boat builder would look at the picture and reply 'what's the big deal?'. Compared to the compound curvatures of a boat hull this job is a piece of cake. Perhaps this picture of one of my DR200s prior to sheathing will help.

Try a search for "bending plywood", "wacky wood" etc. This is thin plywood with the grain in all layers running in the same direction...very easy to bend and laminate to the shape you want. Available in birch, etc...roughly $25 per 4x8 sheet. Lumber yards may not stock it, but they can order it for you.
