With a response of 48Hz-150Hz ± 3dB, the ultra-compact size of the SX112 makes it an ideal partner for ADORN or CDD Series systems where space is at a premium or where the subwoofers need to be hidden. The enclosure is constructed from plywood and has an impact-resistant finish, while the driver is protected by a rigid perforated steel grille, which is pre-curved to withstand physical damage.

Finished in black (RAL9005) or white (RAL9016) as standard with integrated flying points, the SX112 can be also be supplied in any RAL colour to order.

When used with full-range systems, crossover and EQ functions can either be performed by the DX0.4, DX0.6 or DX4.0 system controllers.
