Turbosound PQ18B 18-Inch Passive Subwoofer

Turbosound PQ18B 18-Inch Passive Subwoofer

The Turbosound PQ18B is a passive subwoofer with a single 18-inch ferrite driver in a bass-reflex enclosure.

Designed for professional mobile, touring and installed systems, it extends the low-frequency output of PQ Series full-range loudspeakers. The enclosure supports conventional placement and manufacturer-defined directional bass configurations.

The PQ18B requires a supported Lab Gruppen amplifier and the matching manufacturer Lake DSP preset. One amplifier and DSP channel is required per enclosure in normal operation, while directional configurations can require additional channels.

Rear NL4 connectors provide input, link and pin-swap functions. A front NL4 connector supports tidy cable routing in directional configurations. A 35 mm M20 socket accepts a pole for a compatible full-range loudspeaker.

The 15 and 18 mm plywood enclosure includes a steel grille, integrated handles and interlocking feet for vertical or horizontal placement. An optional wheel kit can assist transport.
