Exciter 25W (2 pcs.) | Harvia
Exciter 25W (2 pcs.) | Harvia

There are no speakers in this sauna. The music is just there — coming from the walls, filling the room without a visible source, without grilles or enclosures interrupting the wood. That's what the Harvia wave.com4 Exciter set does: two electromagnetic transducers mount on the outside of your sauna wall or ceiling with wood screws, and the vibrations they produce travel through the paneling itself, turning the wood into the speaker. Each unit delivers 25 watts, and the sound that comes through depends on the wood — its thickness, species, and the size of the room behind it. Cedar sounds different from hemlock, a thick wall different from thin paneling. It is an inherently room-specific experience, and the result in a well-built sauna is immersive in a way that a conventional speaker mounted on the wall isn't. The exciters connect to the Harvia wave.com4 Bluetooth module, sold separately, which handles the amplification and wireless connection to your phone. For builders who want audio to be part of the room rather than added to it, this is how you do it without cutting a single speaker hole.

The wall is the speaker. Two 25W electromagnetic transducers mount on the exterior of your sauna wall or ceiling and transfer vibrations directly through the wood paneling — no speaker grilles, no enclosures, no visible audio hardware inside the room.

50W combined, zero visual impact. Each unit delivers 25 watts; together the pair outputs 50W through whatever surface they're mounted on. The sauna interior stays exactly as designed — the sound is the only evidence anything is there.

Sound shaped by the wood itself. Acoustic output varies with the thickness, species, and dimensions of the wall or ceiling surface being excited. Cedar, hemlock, and spruce each have their own character. The result is room-specific and can't be replicated by a conventional speaker at any price point.

Mounts on the exterior — dry area only. The exciters are rated to 70°C and mount on the outside face of the sauna wall or ceiling with standard wood screws. They are not rated for interior sauna installation — a different approach than ceiling-mounted speakers, and a simpler one once the sauna is paneled.

Requires the wave.com4 Bluetooth module. The WC4-BT-EXC exciters are signal transducers, not amplifiers. They require the Harvia WC4-BT Bluetooth module (sold separately) to receive audio signal and power. The exciters alone produce no sound without the amplifier module connected.
