Name: Blackline Q8
Rating: 4.7 (23 reviews)

Blackline Q8 is an ultra-compact, passive two-way loudspeaker featuring an 8” (200mm) LF driver with a 2” (50mm) voice coil and a 1” (25mm) exit HF compression driver with a 1” (25mm) dome. It has a Differential Dispersion horn for wider and more consistent coverage, which can be easily rotated for horizontal or vertical orientation depending on deployment needs. Despite its small size, Q8 delivers impressive performance, achieving a peak SPL of 121dB (127dB with crest factor 4).

Applications

Portable sound reinforcement
Unobtrusive stage monitoring
Live music clubs
Corporate events
Bars and restaurants
Nightclubs
Houses of worship

As a stand-alone loudspeaker, Blackline Q8 offers exceptional versatility across a wide range of professional applications — from distributed sound reinforcement and houses of worship to AV events, front-fill/in-fill duties, and even as a compact stage monitor.

When paired with a BlacklineQ subwoofer, it becomes a simple yet powerful system ideal for portable use or fixed installations requiring an unobtrusive solution capable of delivering pristine sound over short to medium throw distances.

Q8 is constructed from durable plywood and finished in a tough black textured paint. It features a screw-fixed steel grille, M6 inserts for wall brackets, M8 inserts for yokes or eyebolt suspension, and a pole-mount socket with a removable cover to maintain clean lines in installed applications.

This full-range, passive two-way system is recommended to be used with a processor and amplifier, or a combined amplifier-processor unit, such as a DX processor and VIA amplifier, or an iKON combined amplifier and processor.

Architectural Specs

Martin Audio Blackline Q8

The loudspeaker shall be a passive, two-way system. Its transducers shall consist of a reflex-loaded 8” (200 mm) low-frequency driver with a 2” (50 mm) voice coil and a 1” (25 mm) exit high-frequency compression driver with a 1” (25 mm) dome, mounted on a user-rotatable Differential Dispersion horn to enable vertical or horizontal orientation of the enclosure.

Horizontal dispersion shall taper from 90° to 110° along the vertical axis to optimise near and far field coverage. Vertical dispersion shall be 50° total (+20° / –30°). The on-axis frequency response shall be 67 Hz to 17 kHz (±3 dB), with low-frequency extension down to 51 Hz (–10 dB). The loudspeaker shall produce a peak SPL of 121 dB (127 dB with crest factor 4) at 1 metre. Nominal impedance shall be 8 ohms. The loudspeaker 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 rear connector panel shall be fitted with two NL4 connectors. The enclosure shall be constructed from multi-angle plywood and finished in black textured paint. It shall be fitted with a pole-mount socket with a removable cover and M6 inserts for wall brackets, as well as M8 threaded inserts to accommodate yoke or eyebolt suspension. The drivers shall be protected by a screw-fixed, perforated steel grille with a cloth backing. An integrated ergonomic handle made from recycled ABS shall be included.

Dimensions (W x H x D) shall be 236 mm x 500 mm x 250 mm (9.3 in x 19.7 in x 9.8 in). Weight shall be 10.1 kg (22.3 lbs).

The loudspeaker shall be the Martin Audio Blackline Q8.
