Sound you hear but never see

During 3 Days of Design 2026, designer Anker Bak launched Dignity Design with the exhibition The Design We Hide Away — five exhibition rooms and an entrance space in a basement near Amalienborg, Copenhagen, temporarily transformed into a gallery. Sound was the invisible thread drawing visitors from the talks at the entrance into the designed spaces beyond. The only infrastructure requirement: a power socket.

The brief: sound as an invisible guide

The entrance room was intentionally silent — a space for daily talks and conversation. The five exhibition rooms beyond were not. The same curated sound played consistently across all five, designed to be felt rather than noticed. The intention was deliberate: visitors in the entrance would sense the music from the rooms ahead and move toward it naturally, drawn from the spoken programme into the exhibition itself.

For this to work, the source of the sound had to disappear. In every room, the speakers were positioned out of sight — behind curtains, or integrated so discreetly into the space that the music seemed to come from nowhere in particular.

"I want people to be drawn into the rooms — not directed. Sound does that in a way that signage never can. It creates a pull. But the moment you see a speaker, the spell is broken. The sound has to be there without being visible."— Anker Bak, designer and co-founder of Dignity Design

The installation: three mounting solutions, one afternoon

The space presented a real installation challenge. A basement not built for audio, temporarily dressed as an exhibition by an interior team that had done exceptional work transforming each room. Every space was different — different size, different surfaces, different possibilities for mounting. A traditional cabled system would have been incompatible with both the timeline and the design.

Three different Spottune mounting solutions were used across the five rooms, each chosen to suit the space:

The speakers in all five rooms were are connected wirelessly to the Spottune Stream. No drilling. No cabling. No electrician. Each speaker needed only a standard 220V power socket — and the entire system was operational within 30 minutes.

The result: a space that sounds as considered as it looks

Visitors at The Design We Hide Away moved through five rooms where sound and design worked together without either competing for attention. Nobody asked where the music was coming from. The interior team's transformation of the basement space was supported at every level — visually and sonically — without a single cable in sight.

For temporary spaces, pop-up exhibitions, and events where installation time is limited and the design cannot be compromised, the Anker Bak installation is a direct proof of concept: wireless commercial audio that adapts to any space, requires only power, and leaves no trace when it leaves.

"Nobody asked where the music was coming from. That is exactly what we wanted. Good design — and good sound — should feel inevitable, not noticeable."— Anker Bak, designer and co-founder of Dignity Design
