The SX212 is designed to be used with full-range loudspeaker systems and extends the low frequency operating range of the combined system down to 40Hz. The enclosure is constructed from plywood and is internally-braced to reduce energy transmission to the enclosure panels and baffle. Its perforated steel grille is pre-curved to withstand damage and it can be supplied fitted with optional flying points.

Finished in black (RAL9005) or white (RAL9016) as standard with integrated flying points, the SX212 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.
