Not sure what they sound like yet. The video shows a 9 volt battery ignition test so I know they will play sound. I'm going to flip n 1/4" MDF for a portable bluetooth build with a 500mah li-ion battery and a 10w bluetooth booster. You could be more careful with the glue they put around d use the external speaker only comes out where the bezel is 10 bucks, that's cool.
