Version 2!

Added speaker grilles, battery level indicator, 2x battery life, and removable handle/legs.

Portable Bluetooth Speaker!

It is very bass heavy, and plenty loud for indoor and outdoor listening. It uses a single 4 inch Dayton Audio midrange driver and a 4 inch passive radiator.

Split into halves to allow for easy assembly and to be printable on a 120mm square build surface.

It uses 6 18650 cells. I used 3000mah Samsung cells in 3s2p and it lasts hours. It can play music while charging.

Build List:

The amplifier is an aideepen TDA7492P from Amazon. Any bluetooth amplifier between 40 and 50 watts with 12v input will work.
