I read this post http://forums.adafruit.com/viewtopic.ph ... er#p165665
I see there is an amp I can use, it is an option, but what is the largest speaker I can use with the waveshield without causing damage and without an amp?
I want to build some louder sound into my bomb prop, because the insects in the bush make more noise than my bomb prop when it "explodes"
Largest speaker to be used with waveshield?

2-3" is about the largest the little op-amp can handle. Our class-D amp will give you more power: https://www.adafruit.com/products/987
Or just plug in any powered computer speaker for a bigger sound.

These are all under 3'' and 8ohm

What is the max Watt I can look at using? I will play a 5 second sound file maximum every 10 seconds, not sure if that helps since the circuits can cool down

The max output of the on-board op-amp is 1/8 watt into an 8 ohm speaker, or 1/4 watt into a 4 ohm speaker. A 4 ohm speaker will be louder than the 8 ohm.
