I call it the iBoo. Made from 3/8” Bamboo hardwood. A total of 40W (20w x 20w) and high efficiency full-range drivers with great bass. Fancy leather handle, Bluetooth connectivity, and rubber, vibration isolating feet.
Theoretically will last several hours with a 12V Battery. Charge from anything with a 12V plug (PSU, Car, Boat, Solar Panels, etc..)
One day when my woodworking skills improve, I’ll hopefully make a few of these. For now, they sit on my hard drive as merely a design.
