excursion 12" neodymium driver in a bass-reflex design.

The 12S-SUB frequency response extends from 45 Hz to

130/100 Hz.

The enclosure is constructed from marine plywood with an impact

resistant black paint finish. The front of the cabinet is protected by

a rigid metal grill backed by an acoustically transparent foam.

Four rubber feet prevent cabinet movement and protect the bottom

panel against scratching.

The cabinet is Ball Impact Resistant according to DIN 18032-3.

The 12S-SUB side panels are each equipped with a pair of M10

threads to accept the Z5412 Horizontal bracket 12S-SUB. The
