Apparently there is an ancient (1979) DIN standard, DIN 45575, which specifies a standard IEC baffle (size, shape, speaker location) used for guitar loudspeaker testing.

For our American friends, the baffle is 4'5" x 5'5". To big to cut out of an 8'x4' sheet of plywood in one piece - you'd have to have at least one join!

The attached screenshot of the DIN 45575 baffle design shows that the standard specifies flush-mounting the speaker to the baffle front face. Not bad for 1979, when many speaker "designers" still hadn't realised how badly the frequency response can be mucked up rear-mounting a driver to a thick wooden baffle.

Sadly, flush-mounted speakers are still rarely if ever seen in guitar cabs.
