Speakers:

Where is it?
The loudspeaker? It disappears inconspicuously in the troughing or in the installation program. Up finery or underfinery - as you wish. With a volume control or an optional mandatory relay. As a 100V-device or in 4, 8, or 20 ohm variants. For language or mood music in houses, hotel baths, crude,… - everywhere, especially small spaces.
