Recommend a small and loud speaker Answered
I'm working on a project that needs a purdy dang small speaker, but it still needs to be loud enough to be heard clearly from about 10 feet away. Now, I know that when you loose size you loose watts and when you loose watts you loose volume, but I was wondering if anybody could recommend a speaker 50-ish millimeters or less in diameter and loud enough to be heard clearly from 10 feet away.
If it helps, I'm working with an Arduino with an Adafruit Wave Shield to make a human voice speak English (American-ish).
Thanks for the help,
