Product Details Q218

Q218 provides direct-radiating bass reinforcement for BlacklineQ full-range loudspeakers. The lower ±3 dB response boundary is 38 Hz, with 142 dB peak output or 148 dB peak with crest factor 4.

The plywood enclosure contains two 18-inch drivers 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.

Four side handles assist handling, while the feet and locating recesses support the specified cabinet orientation and horizontal stacking. 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.
