This boom box survived for a much longer period of time than the Boom in da box – v1.0 and Chill out box 2011. It was alive and kicking between 2012-2019

Created from sturdy 13mm plywood paired with 6x9" JBL speakers this thing was a beast, design inspired by the black boxes in airplanes for some reason. Total operational weight: 20-30kg depending on battery :-)

During the years it survived some abuse and a couple of incidents and only needed minor repairs (like a new battery

Cleaning out old hard drives can mean that sometimes you come across old treasures.

Back in 2011, for the music festival Peace and Love I wanted to bring my trusty home built “boom-in-da-box” (see previous post). However, the rules for the festival camping stated that no lead-acid batteries were allowed into the area and the “boom-in-da-box” ran on a car battery + 600W car-amplifier.

To fix this I needed two things:

More energy efficient 12V amplifier.
Smaller speakers.
A box to build in.

I opted to build the speaker inside of an empty wine box, a “chill out” boom box was born. It lasted the festival, but mono-sound and the hassle of AA’s meant this box eventually died.

Below is a first version of the boom in the box, anno 2011.

It was built to play music outdoors, engineered to be cheap and loud (and with surprisingly high quality if you didn’t max out the poor old Volvo V40 car speakers from 1998).

This box was active for about 1-2 years and repaired a few times after it had had too much dancing ( it fell of bikes more than once, you can see the boxes changing color and style in the pictures).
