Martin Audio Blackline Q118 18" Passive Subwoofer with 4" Voice Coil Black

Description

Blackline Q118 is a compact, high-performance subwoofer designed for use with Blackline Q Series full-range loudspeakers. It extends the system’s low-frequency response down to 38Hz and delivers exceptional impact, with a peak SPL of 130dB (136dB with crest factor 4).
Q118 features an 18” (460 mm) driver with a 4” (100 mm) voice coil, housed in a durable plywood enclosure finished in tough black paint. A perforated, impact-resistant steel grille protects the driver, while slot ports enhance efficiency and minimize noise turbulence.
Designed for versatile deployment, Q118 can be used individually, stacked or flown using integral M10 inserts. It also includes an M20 1.4” (35 mm) pole-mount fitting for seamless integration with other loudspeakers in BlacklineQ series. There are two signal link outputs—one positioned at the top and one at the bottom of the enclosure when oriented vertically. This allows for flexible, discreet and tidy signal connections to other BlacklineQ loudspeakers, regardless of setup.
Ergonomic side handles ensure easy handling and rubber feet on the base align with top-surface recesses to provide secure and stable stacking. A castor kit is available as an optional accessory.
When paired with BlacklineQ Series full-range systems, crossover and EQ functions can be managed via the DX0.4, DX0.6 or DX4.0 system controllers, or the onboard DSP of an iKON amplifier.
