TOA / BS-4D

Heat-resistant speaker exclusively for dry saunas, using a heat-resistant 12 cm full-range speaker unit. A sealed speaker system, using spruce wood from North America for the enclosure. Since the structure does not allow hands to touch the metal parts when installed, there is no need to worry about burns even if the speaker is installed in a constantly hot place such as a dry sauna bath. In addition, the spruce wood of the enclosure is often used for sauna interior materials, so it matches the interior design.
