SMS-HDN

Hidden within the plenum and mounted to the back of suspended ceiling tiles or gypsum board drop ceilings, the SMS-HDN converts these ceiling surfaces into large loudspeakers, providing an impressively diffuse and
clear sound field.

When used in closed offices, the SMS-HDN speaker allows for independent volume control of the masking sound between adjacent offices or open areas. This solves the problem of masking sound leakage between adjacent areas through the open plenum. The SMS-HDN is also an improved alternative to surface-mounted speakers in the case of gypsum, wood or any drop ceilings. Unlike surface or direct-field speakers, the SMS-HDN does not create acoustical hot spots, providing a significantly more diffuse sound field for excellent sound masking uniformity.

The SMS-HDN provides an innovative alternative to surface speakers to obtain uniform sound masking, clear paging & music, and without any compromise on the esthetic of the ceiling.
