Anyone here have successful experience with tiny speaker enclosure design?
Getting very mixed results on 'speaker enclosure calculators' and other general tip/hint sites. One is telling me a 4 meter reflex tube should be good and others tell me a straw sizes tube should also work fine.

I need: maximum sound quality, minimum space usage. Weird shapes is not a problem (curved tubes or so is possible)

Concept will 'slightly' change from original plan, to keep it simple.

- audio via 3.5-jack
- 2 speakers
- fancy speaker housing
- amplifier
- stepup to 5V #moarpower
- microusb port for #moarpower and charging
- invisible touch buttons for various functions
- borrow diptoh software
- maybe external speaker connectors #extremepower

Are you sure that you don't want to include the fm-transmitter
