Good plan. And if that doesn't do it, low profile bolts could be used to gain even more space. The forces on the wheels are pretty tiny.
Another small update:
Added some code to work with the scanner. And some hardware changes:
Counterweight is working. Motors can be turned off, no more whining noise:
All it took were some standard nuts:
I mounted the (bulky) arduino box:
And used a banana plug thingy instead of my protoboard to get power to the CNC shield:
It's starting to clean up nicely (for a prototype).

I added a counter weight to the scanner. Untill now, the speaker had been acting as the counter weight.
Does anyone have any ideas about the servo and microphone cables? I would like to keep them under control and not drag them around (e.g. over the table). Depending on the position of them microphone I could have 1.4 meter of microphone cable hanging free/lying around.

In the CNC world something like this is typical. They are designed for linear motion, though, so likely only a partial solution.
Maybe spiral cable wrap would be helpful as well.

Of course you could do that. I would need (to buy) another microphone, microphone cable, audio interface, profiles, stepper motors, ...
Also, how do I say this... The position of a single mic is easily known relative to its starting position. A second mic would need its position known relative to the first one or one needs an algorithm to deduce that from measurements.
So using a piece of iron as a counterweight was a bit easier.

I don't follow.
The second mic is just the same + 180 degrees (+ additional error correction at first setup).
Since both are connected to the same arm (beam) the relative error is basically non existent.
So it's actually quite simple.
