Martin Audio BlacklineQ Q8-B – 8" Passive Two-Way PA Cabinet

Product Overview

The Martin Audio BlacklineQ Q8-B is an ultra-compact 8" passive two-way loudspeaker engineered for portable sound reinforcement, stage monitoring, and installation applications where a minimal physical footprint is essential without sacrificing professional output performance. Built around an 8" LF driver with a 2" voice coil and a 1" exit HF compression driver featuring Martin Audio's Differential Dispersion horn technology, the Q8-B achieves a peak SPL of 121dB (127dB with crest factor 4) from a cabinet that can be repositioned by a single operator. The Differential Dispersion horn delivers a wider and more consistent coverage pattern — 90°–110° horizontal by 50° vertical — than a standard constant-directivity horn, and is user-rotatable for horizontal or vertical orientation to suit the deployment context. The Q8-B represents Martin Audio's entry in the BlacklineQ Series, a more recent evolution of the BlacklineX design philosophy emphasizing sustainability and advanced horn technology.

Product Description

The Martin Audio BlacklineQ Series introduces Differential Dispersion horn technology to the BlacklineX design philosophy, delivering wider and more consistent audience coverage from a compact passive loudspeaker form factor. The Q8-B is the 8" two-way model in this series and is positioned for applications requiring professional output performance in the smallest possible enclosure.

The LF section uses an 8" (200mm) driver with a 2" (50mm) voice coil, which provides the power handling and cone area required for music reinforcement in near-field applications, monitor positions, and distributed fill systems. The HF section uses a 1" exit compression driver with a 1" (25mm) dome diaphragm, paired with the Differential Dispersion horn that provides a 90°–110° horizontal by 50° vertical coverage pattern for wider and more even audience coverage than standard dispersion horns in this cabinet class.

The Differential Dispersion horn is user-rotatable, allowing operators to switch between vertical and horizontal coverage orientations without tools. This flexibility is especially valuable in rental applications where the same cabinet may be used as a front-of-house fill, a stage monitor wedge, or a portable PA satellite across different events.

The symmetrical multi-angle plywood enclosure supports vertical and horizontal deployment orientations. The enclosure features M8 inserts for wall bracket mounting and eyebolt suspension, a pole-mount cover that maintains clean lines in installation applications, and two NL4 connectors for loop-through wiring in distributed systems. The integrated ergonomic handle is manufactured from recycled ABS, reflecting Martin Audio's sustainability commitments in the BlacklineQ design. As a fully passive system, the Q8-B operates without a processor, though integration with a DSP controller or compatible amplifier is recommended for subwoofer-paired deployments.

Frequently Asked Questions

What is Differential Dispersion technology and why does it matter?

Differential Dispersion is Martin Audio's proprietary horn geometry that delivers a wider and more consistent coverage pattern (90°–110° horizontal x 50° vertical) compared to standard constant-directivity horns of similar size. In practice, this means more even SPL distribution across the listening area with reduced off-axis coloration, which is particularly valuable in near-field and distributed fill applications.

How does the Q8-B differ from the BlacklineX X10B?

The Q8-B uses an 8" LF driver versus the X10B's 10" driver, making it more compact with a slightly lower maximum SPL. The Q8-B introduces Differential Dispersion horn technology providing a wider 90°–110° horizontal pattern compared to the X10B's 90° fixed-mouth horn. The Q8-B is the preferred choice when physical size is the primary constraint; the X10B offers greater output and low-frequency extension for applications with more space.

Can the Q8-B be used as a stage monitor?

Yes. The multi-angle plywood enclosure allows the Q8-B to be positioned as an unobtrusive passive stage wedge monitor. Its compact footprint and high SPL for an 8" cabinet make it practical for vocal monitoring on small-to-medium productions where a larger wedge would be intrusive.

What subwoofers pair with the Q8-B?

The Q8-B is compatible with BlacklineX Series subwoofers including the X115B (15"), X118B (18"), and X218 (dual 18") for full-range satellite-over-subwoofer portable PA configurations. Crossover alignment is managed via a compatible DSP controller. See the full range at creationnetworks.net.

Does the Q8-B require a DSP processor?

No. The Q8-B operates as a full-range passive two-way system without a DSP controller. A controller is recommended when pairing with a subwoofer to manage active crossover, EQ optimization, and driver limiting.

Is the Q8-B suitable for permanent installation in a house of worship?

Yes. M8 inserts support wall bracket mounting and eyebolt suspension, and the pole-mount cover maintains a clean aesthetic when the pole socket is not in use. These features make the Q8-B well-suited for underbalcony fills, aisle coverage, and distributed delay fills in houses of worship, auditoriums, and conference spaces.

What does the recycled ABS handle signify?

The integrated ergonomic handle on the Q8-B is manufactured from recycled ABS plastic as part of Martin Audio's environmental sustainability commitments in the BlacklineQ Series design. This is in line with broader industry moves toward reducing the environmental footprint of professional audio equipment without compromising structural integrity or ergonomics.

Where can I purchase the Q8-B at the current sale price?
