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.

Martin Audio Blackline Q210
The subwoofer shall be a passive, direct-radiating system. It shall feature two 10” (250 mm) low-frequency drivers with 2” (50 mm) voice coils, housed in a slimline plywood enclosure with slot ports to enhance efficiency and reduce air noise.
The on-axis frequency response shall be 49 Hz to 100 Hz (±3 dB), with low-frequency extension down to 41 Hz (–10 dB). The subwoofer shall be capable of producing a peak SPL of 124 dB (130 dB with crest factor 4) at 1 metre. Nominal impedance shall be 4 ohms. The system shall require external amplification and processing. For optimal performance, it shall be used in conjunction with a dedicated electronic controller such as a Martin Audio DX series processor, paired with a VIA series amplifier, or with an iKON series combined amplifier and processor.
The enclosure shall be finished in durable black or white paint and fitted with a perforated, impact-resistant steel grille. It shall include an M20 / 1.4” (35 mm) pole-mount socket for use with full-range loudspeakers and three NL4 connectors, one of which shall be positioned for linking when the Q210 is in a vertical orientation. The cabinet shall also include integral ergonomic side handles, M8 flying inserts and rubber feet for both vertical and horizontal operation. Rebate recesses shall be provided for secure horizontal stacking.
Dimensions (W x H x D) shall be 296 mm x 718 mm x 462 mm (11.7 in x 28.3 in x 18.2 in). Weight shall be 22.4 kg (49.4 lbs).
The loudspeaker shall be the Martin Audio Q210.
