Turbosound PQ18B 18" Reflex-Loaded Passive Subwoofer

The PQ18B is the subwoofer that sits under the Turbosound PQ full range cabinets, a reflex-loaded single 18" box for live production work. The driver runs a 4" copper voice coil on an FEM optimised motor with a double silicon spider.

Output is omnidirectional and rated 700 W continuous, 2800 W peak into 8 ohms, with 99 dB sensitivity at 1 W and 1 m and 138 dB peak SPL. At 47.9 kg it is a two-person lift, and the crossover is passive so one amplifier channel drives the cabinet.
