Soft dB's SMS-STR is a 25-volt loudspeaker system designed to generate optimum sound masking for a variety of ceiling conditions.

It is equipped with a 13 cm (5 in.) driver installed in a sealed compartment.

The design is ideal in open structure ceiling configurations since the speaker, terminal and switch are hidden when the speaker is hung from the deck. It can also be installed above a suspended ceiling in typical sound masking installations.

A rotary switch allows quick adjustment of the output level with a 4W, 2W, 1W, 1/2W, 1/4W position available at 25V. The loudspeaker is also compatible with 70V systems with an available 8W, 4W, 2W adjustement.
