Turbosound iQ18B Powered Subwoofer

Turbosound iQ18B 18-Inch Powered Subwoofer

The Turbosound iQ18B is a 18-inch powered subwoofer with a KLARK TEKNIK amplifier and DSP.

It extends the low-frequency output of full-range loudspeakers in live music, DJ and installed sound systems. The DSP menu includes alignment presets for the iQ8, iQ10, iQ12 and iQ15.

The built-in Class-D amplifier delivers a maximum output of 3000 W. Crossover, equalisation, phase and delay settings allow the subwoofer to be adjusted to the system, while limiting helps protect against overload.

Two XLR / 6.3 mm combination inputs accept analogue signals. The XLR outputs pass unprocessed copies of the corresponding inputs to other powered loudspeakers. ULTRANET carries digital audio between compatible devices, and USB supports DSP control from a computer and firmware updates.

Rear-panel buttons and a rotary encoder provide access to settings shown on the LCD. The birch plywood cabinet has a 35 mm pole socket, and the supplied castors make it easier to move.
