Martin Audio Blackline Q210 Passive 2 x 10" Subwoofer - White

Blackline Q210 features dual 10” (250mm) drivers with 2” (50mm) voice coils, housed in a robust plywood enclosure. A perforated, impact-resistant steel grille protects the drivers, while slot ports ensure efficient airflow and reduced turbulence for clean, controlled bass performance.

Finished in durable black paint as standard, Q210 is also available in white to support visually sensitive installations, particularly when paired with BlacklineQ column loudspeakers in white.

Q210 can be deployed singly, stacked or flown using integral M8 inserts. It 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.

Two ergonomic side handles provide ease of handling, while rubber feet on the base align with top-surface recesses to ensure stable stacking. Q210 is ideal for applications requiring compact, high-performance low-frequency reinforcement.

When used 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.
