Harvia Exciter 25W 2 pcs | WC4-BT-EXC

Invisible Structure-Borne Audio for Seamless Sauna Sound

The Harvia Exciter 25W 2 pcs is an innovative sauna audio component designed to create an almost invisible music experience through structure-borne sound technology. Rather than producing sound through a traditional visible loudspeaker, each exciter transfers vibrations directly into a compatible surface, allowing the wall or ceiling itself to reproduce audio while preserving the clean architectural appearance of your sauna.

The set includes two 25 W electromagnetic exciters, making it ideal for sauna and wellness environments where discreet, integrated sound is preferred over conventional speakers. By eliminating visible speaker grilles, the system delivers high-quality audio without interrupting the visual harmony of the sauna interior.

Designed for installation with compatible amplifiers, sauna control units, or external audio systems, the Harvia Exciter system is intended for custom audio installations where professional planning ensures optimal performance. Sound characteristics depend on the material, dimensions, shape, and construction of the surface receiving the vibration, allowing each installation to create its own unique acoustic signature.

At Between Living, we believe exceptional design often disappears into the background. The Harvia Exciter transforms the sauna itself into the speaker, allowing sound and architecture to work together in perfect harmony.
