The OSD BK-100W70T indoor transformer allows you to convert standard 8-ohm speakers into 70V speakers for use in a commercial-style custom-installed sound system. With taps at 20, 40, 60, 80, and 100 watts, it allows you to daisy-chain the 8-ohm speaker together with multiple additional 70V speakers, all driven by a single amp. It is rated for indoor use only.
