The outside dimensions of the H290C are 11.63" wide x 6.56" tall x 5.90" deep. Most of it is 0.25" thick, although some portions are thicker. The front "lip" is 0.25" thick; Driver mounting bracket is a little thicker. Corners are radiused at 0.8". That's what you would cut into the baffle with a router for a flush mount.
