Unfortunately I was not able to find the final quotes and drawing but it’s quite easy to measure after dismounting the rear panel.
I request a local supplier to cut and bend me the “stair” in a 2 mm aluminium panel plus the two lateral panel in “L” solded laterally to close the « stair »
Cost 48 €.
There is no bottom, I just use a thick tissue to do the bottom.
The easy tip is to use the wood speaker mount to fix the assembly after the panel is put in place by just doing a 2mm cut in the wood to press the « stair » against the rear panel with the speaker srew.
Pay attention to two stuff :
- there is a rivet in the middle that is bellow the last frame so a little cut in the top of the « stair » is needed
- don’t forget to cut a 5x30 mm in the middle of the bottom of the stair to allow the cabling passage
For the rectangle hole in the panel up to you to see what is the best (I did it 40mm smaller that the « stair » and with the high needed to allow the passage of the anti-puncture cylinder.
Sorry for the bad wording I am French …
