BlacklineQ Series | Signature sound for portable and installation applications

Intelligence in Every Application

For over 25 years, Martin Audio’s Blackline Series has set the global benchmark for affordable professional loudspeakers—renowned for their exceptional sound quality and reliability.

BlacklineQ is a reimagining of this iconic series delivering improved passive two-way point source loudspeakers, all-new column speakers and a suite of subwoofers. The entire series features intelligent design details, making it equally at home in portable or install applications.

Where to Buy or Rent

Coverage, Consistency and Control

Like everything we do, BlacklineQ extolls the virtue of meticulous acoustic design to deliver improved coverage, consistency and control.

For the first time in its class, both full-range two-way point source systems and column speakers feature Differential Dispersion technology which focusses the energy the in the top of the waveguide into a tighter horizontal pattern for improved projection into the far-field.

Conversely, at the bottom the opening angle widens out to cover the front of the audience seamlessly. In addition to this, a slight downward angle has been incorporated into the waveguide design to direct more of the high-frequency content down into the audience and not upwards into the surrounding walls and ceiling.

The result is sound targeted exactly where it's needed, with less energy lost into the reverberant field for clearer, more consistent coverage across your audience.

Hot spot directly in front, with weaker coverage further out and to the sides. To compensate, additional loudspeakers with overlapping coverage may be required.

Full range point source loudspeakers

Each symmetrical, multi-angle full-range passive enclosure features a rotatable Differential Dispersion horn for horizontal or vertical deployment. A cloth-backed, screw-tight steel grille provides both protection and access to the drivers, while the larger speakers feature ergonomic handles finished in recycled ABS plastic. These provide convenient mobility while maintaining clean lines.

Transit covers and comprehensive mounting options—including wall brackets, yokes, eyebolt suspension, and pole mounts—ensure that BlacklineQ is equally suited to portable use or installation. A pole-mount cover provides a clean, streamlined appearance when the mount is not in use.

Two-way Column Speakers

BlacklineQ marks Martin Audio’s debut in column speaker design with the two-way passive Q44 and Q26 offering elegant, discreet solutions for both portable and fixed use.

Finished with hard wearing black or white paint, each plywood enclosure features Differential Dispersion technology for consistent coverage and intelligibility, suited to both voice reinforcement and refined musicality.

As with the point source loudspeakers, transit covers and comprehensive mounting options—including wall brackets, yokes, eyebolt suspension, and pole mounts— support flexibility of deployment. A pole-mount cover provides a clean, streamlined appearance when the mount is not in use.

Subwoofers

BlacklineQ includes a trio of passive subwoofers extending low-frequency performance across the series.

The enclosures are constructed from durable plywood and feature slot ports for efficiency in design while reducing noise turbulence. Each enclosure includes an M20 35mm (1.4”) pole-mount fitting for seamless integration with all loudspeakers in the series. In addition, the link out socket is positioned at the top of the cabinet, providing a convenient and discreet solution for connecting the cable for a BlacklineQ loudspeaker on a pole.

Finished in hard wearing black paint as standard, the Q210 is also available in white to match the white BlacklineQ column loudspeakers.
