The X118 is a compact, high performance passive subwoofer for use with BlacklineX Series full-range loudspeakers.

It extends the low frequency operating range of the combined system to 42Hz and provides exceptional low frequency impact.

This subwoofer can be used singly, stacked or flown via integral M10 insets and features a long-excursion 18” (460mm)/3” (75 mm) voice coil driver in a compact reflex enclosure. Its four reflex ports have a large frontal area to reduce turbulent air noise at very high levels.

The X118 enclosure is constructed from plywood and finished in black textured paint as standard, with white and RAL colour finishes available to special order. An impact-resistant perforated steel grille protects the driver, and the enclosure has a 35mm pole-mount fitting in the top surface and two side handles for ease of handling. Rubber feet on the base of the enclosure resist movement and align with recesses in the top surface for stable stacking.

When used with BlacklineX Series full-range systems, crossover and EQ functions can be performed by the DX0.5 system controller or by an MA Series [Electronics] amplifier with on-board DSP option.
