Step 2: Testing and preparation
Before you design and cut the parts, you need to test that the system is working well, this is simple to test; hook up both speakers, plug in an input, add a power source and test! (Picture 1)
At this point I advise that you prepare the parts so that you don't have any problems after you've cut the acrylic.
What you have to prepare depends on your components, but for me it was the volume dial; it wasn't at 90o, so I couldn't put it flat on a laser cut box. (Picture 2) To fix this, I took off the casing this showed me that the volume dial was a separate PCB and could be moved to suit my desired location. (Picture 3)
If you had to modify your speakers in another way, please leave a comment with pictures and I will include it.
