DIY Kit
The Berlin Boombox comes as a DIY kit consisting of a die-cut cardboard structure and all electronic parts.
Assembly is easy and takes only a couple of minutes. You don't need any geeky knowledge, no glue or tools to build the Berlin Boombox.

High Quality
Our products are designed with a dedication to detail and are produced locally in Berlin.
All audio components are German engineered. The sturdy cardboard construction is optimised for best possible sound.
The Berlin Boombox features a strong carrying handle and a beautiful aluminum knob.

Eco-friendly
Less Garbage
The Berlin Boombox is made of recycled cardboard* and can itself be recycled. It only contains a small portion of plastic and electronic waste. We also avoid unnecessary plastic packaging materials.
*Brown colorway: 100% recycled cardboard. Other colors: partially recycled cardboard.
Efficiency
The lightweight and flat packaging means less energy is used for shipping. Our class D amplifier is very energy-efficent.
Supporting local Businesses
All design, screen-printing and production of the cardboard case is done locally in Berlin. Packaging and logistics are done by a sheltered workshop..
Modular Concept
The modular kit concept of the Berlin Boombox allows for easy repair.
The Berlin Boombox is the most eco-friendly powered stereo speaker on the market.

Our Story
Music & Design
Axel Pfaender is an illustrator, designer and DJ. In 2012 he decided to combine his two passions – music and design and created the Berlin Boombox.
Kickstarter
In 2012 Axel launched a Kickstarter project to get the necessary funds to bring the Berlin Boombox to the market. Even more valuable than the money raised was the positive feedback from his backers, retailer inquires and press coverage that followed. A real highlight was the visit by Kickstarter founder Perry Chen who personally checked out the first prototype.
Bringing Crowd-Funding to Germany
The Berlin Boombox was one of the first German kickstarter projects. Axel Pfaender has held several talks on the topic and has helped other crowd-funding projects as an advisor.
What's next?
After the original black and white model we have been continuously developing new colorways and designs. The Berlin Boombox is available at retailers worldwide - find a store near you with our Store Finder.
