Turbosound TQ18B 18" Reflex-Loaded Passive Subwoofer

The TQ18B is the large subwoofer for the Turbosound TQ line, a reflex-loaded single 18" cabinet on a neodymium motor. It is the box to reach for when the TQ15B runs out of extension rather than level.

Output is omnidirectional, rated 1000 W continuous into 8 ohms with 138 dB peak SPL and 96.5 dB sensitivity at 1 W and 1 m. Neodymium keeps the finished cabinet at 40.7 kg, and the Lab.gruppen PLM+ preset library carries the crossover settings that align it with the TQ full range boxes.
