I have a huge project going on at work right now, and loud music is absolutely essential.  I ordered some Boss CH3220 140W speakers and used a 25W bluetooth audio amplifier board and whipped up in one evening a killer work speaker that kicks hard.

It is working great as is, but I am totally not done.  I am going to add a raspberry pi to play my saved mp3’s and roll some of my own features.

I am very impressed with the quality of the sound and how easy it was to pair with this board.  I tested the speakers with ‘dont tread on me’ by metallica.  The frequency response of these 3.5″ speakers is surprisingly very good.
