Speaker

My idea is to make a cheap speaker with an adjustable bottom, manually or automatic, for tunning the sound

  1. Using lasercut bendable plywood as the case
  2. Making a amplifier
  3. 3D-print or mill the cone
  4. Construct a mechanism there will move the bottom up and down

The idea is to make a cheap speaker, there can be used in FabLab workshops.
Therefore I want to find some cheap solutions there also gives possibility for adjustments and personification of the speaker.
It will be a pretty simple speaker, but I also want to explore the possibility's for tuning the sound by changing the volume
of the "cabinet" by moving the the buttum up and down; with the use of a step-motor, or maybe a servo.
