enclosure: no idea, any Hammond enclosure recommendations? How to secure the box to a table?
- We don't carry an enclosure for either the WAV Trigger or Tsunami, but anything they fit in should work. If you have access to a 3D printer or laser cutter, you could even [[make your own](https://learn.sparkfun.com/tutorials/getting-started-with-3d-printing-using-tinkercad)! Just remember to give yourself a little room for cables and other connections you need to make to the board.

media player: Tsunami Wav Trigger
- WAV Trigger or Tsunami will work great. If you need to save a few bucks and don't need multiple independent outputs, I'd go with the WAV Trigger.
16 knobs: no idea, are there inexpensive 16 button keypads? Or numbered knobs?
- You might consider our concave arcade buttons for this. They are available in 6 colors and stand up to abuse well. (These are the same type of buttons used in pinball and arcade games.)
headphone: what over ear types have good passive noise reduction, max 100 euro? How to secure the headphone?
- I can't help with a headphone, but for securing, I'd recommend something you're able to clamp down on the cable so that they are hard to steal, but easy to replace later on if they wear out.
