Product Details Q118

Q118 provides direct-radiating bass reinforcement for BlacklineQ full-range loudspeakers. The lower ±3 dB response boundary is 38 Hz, with 136 dB peak output or 142 dB peak with crest factor 4.

The plywood enclosure contains one 18-inch driver with 4-inch voice coils. Slot ports improve airflow and reduce turbulence, while an impact-resistant perforated steel grille protects the drivers. The standard finish is hardwearing black paint.

The cabinet can be used individually, stacked or suspended through its integral M10 points with approved hardware. The M20/35 mm pole fitting supports compatible top loudspeakers. One input and two link positions provide three NL4 connections; with the cabinet upright, the links at opposite ends support tidy system wiring.

Side handles assist handling, while rubber feet and matching recesses stabilise the specified stacking arrangement. An optional castor kit is available.

DX0.4, DX0.6 or DX4.0 can provide crossover and EQ when used with suitable power amplification. An iKON amplifier can alternatively supply the required processing through its onboard DSP.
