Eternal Research’s Demon Box Ready for the World—and Superbooth

Innovative instrument company returns to Superbooth in celebration of the public launch of its much-anticipated first instrument.

Eternal Research is devoted to uncovering the hidden sounds of the world around us. Its first instrument, the Demon Box, turns EMF into sound via a set of 33 inductors, letting artists make music from anything they can imagine, from vintage electronics to smart phones. Wildly successful on Kickstarter, the Demon Box is now ready for full commercial release. 

The final prototypes of the striking triangular instrument made of folded steel will be ready by late spring, with orders officially starting on July 1 and units shipping by September. This milestone will be celebrated at this year’s Superbooth, where some of the first Demon Boxes will be ready to hum, sing, and roar. 

“The Demon Box is a physical manifestation of a bigger idea. It’s an idea in contrast to the idea that all the organizing principles we’ve hitherto devised are music, and all that is not part of that is noise,” explains Eternal Research founder Alexandra Fierra. “Additionally, it’s about the idea of the inverted pyramid, to invert all the previous concepts of music into a new theory, making Demon Box the first intentionally designed instrument of a new symphony.”

This new symphony operates along different principles, leading to radically different sounds. By harnessing electro-magnetic fields (EMF) and using a proprietary system of inductors to translate these signals into sound, the Demon Box can "play" the EMF signatures of devices like cell phones, TVs, and hairdryers—turning the silent world of electricity into music. 

Demon boxes can mesh with nearly any set up, thanks to their comprehensive connectivity: three mono audio outs, one MIDI out sending CC and note data, a stereo headphone jack, and a USB-C port for charging or output. Each of the three EMF channels features a dedicated aux input with individual blend controls, enabling sound design with external gear. According to Eternal Research’s head engineer Bryn Nieboer, “Stereo is limited. Three channels create an immersive, triphonic sound that sets the Demon Box apart.”

Eternal Research will exhibit at Superbooth 2025.

• Booth number: Z065, located in the Zeltstadt (Tent City), ZW section.

• Exhibition hours: 10 AM–7 PM, Thursday through Saturday, May 8–10.

• Location: FEZ-Berlin, Germany.
