hi guys, first of all, do you feel it was intentional to not provide any hole for the speakers?? … for me the sound was weird, hidden…, so when I did my screen replacement (thanks for package, fast, okay), I also took drill and did 2mm holes in the center of speakers “cages” … tested now and it is far better, imho

Yes mentioned this last April and saddened the holes would go through the front logo’s 🙄

> It’s here ! First thoughts, will update as I go along… Issue 2.0 board ? (CPI 2.0) Unable to shine hi lumen light through the board to see possible clear areas for spi device mounting posts. Due to black finish and filling all unused areas with copper (saves acid during production process and increases heat spreading, improves electrical noise issues). Speaker slots have no holes to allow the sound out ?. Shame ‘CLOCKWORK’ and ‘ON/OFF’ printed right where they could…

Seems like a larger cut and 3d printed grills would be nice.

just tip to test for “aesthetics” … I have the holes in the center of rectangles, maybe (not tested), that moving say 1.5 mm holes into “O” letters this way will have the same effect …
