The gaps between the surface and the corner radius will be filled by a first layer of 2mm cardboard followed by 5mm plywood to bring it flush to the surface.

The change in materials makes it more difficult for vibrations to travel through and damps the panels.
Haven't you considered using MDF? It seems this material is almost unanimously considered as being the most convenient for fixed loudspeakers. Inherently self-damping combined with ease of milling and smooth finish; only drawback is it needs T-nuts for speaker mounting.

I did consider it, but in the thickness I require, it would have been too expensive.
There is also the health aspect of working with MDF, I don't have dust extraction equipment.
Where I live, I do not have access to all the products available in a large city, so with extra time (which I do have) I can make do with what I have.

is anyone else missing pictures here?
Check your security settings.  The pictures are on Tinypics which comes up as not secure, so your computer might be blocking the site.

Both speakers are now complete as far as the structure is concerned.

This is a cross-section of the cabinet wall.



15mm particle board, 2mm cardboard and 5mm plywood.  22mm total.



This is the first speaker prepared with a coat of primer.

The final colour will be deep blue though.
