Canton Movie Speaker stand 25° tilted

The stand is 25° tilted, speaker facing down.
I have mounted front speakers of my surround system over the top of the furniture where my TV is located, 2.5 mt high.
Rear speakers are wall mounted at 2.8 mt near the roof. (I will publish the spacer used to tilt them)
The pin for the speaker hole has 8mm diameter.
The distance from the center of the pin and the front of the speaker is approximately 91 mm.
The front of the speaker is 88 mm width.
It fits perfectly my Canton Movies speakers bu
