Martin Audio BlacklineX X12B – 12" Passive Two-Way PA Cabinet

Product Overview

The Martin Audio BlacklineX X12B is a 12" passive two-way PA cabinet engineered for portable sound reinforcement in live event, rental, and installation contexts. Constructed around a high-BL motor 12" LF driver and a 1" exit compression driver on a user-rotatable horn, the X12B delivers controlled, high-output coverage for medium-throw applications. Its symmetrical multi-angle plywood enclosure supports both vertical and horizontal orientation, making it adaptable for front-of-house stacks, monitor positions, and distributed fill systems. When paired with a BlacklineX Series subwoofer and a DSP controller such as the Martin Audio DX0.5, the system scales from a compact portable PA to a full dance-floor reinforcement rig.

Product Description

The Martin Audio BlacklineX Series represents Martin Audio's professional portable loudspeaker line designed for the demands of live sound reinforcement, rental inventory, and semi-permanent installation. The X12B sits at the core of the series as a versatile 12" two-way passive loudspeaker capable of operating as a standalone full-range cabinet or as the satellite component in a subwoofer-satellite configuration.

The LF section uses a 12" (300mm) driver with a 2.5" (63mm) voice coil and a high-BL motor for extended low-frequency output and improved power handling. The HF section employs a 1" exit compression driver with a 1.75" (44mm) poly-imide diaphragm, delivering extended high-frequency response critical for speech clarity and instrument articulation in live environments.

The rotatable 80° x 50° constant-directivity horn allows the operator to adjust the coverage pattern without re-positioning the cabinet, a practical advantage during rapid changeovers on touring and rental deployments. The X12B operates at 8Ω nominal impedance and uses twin NL4 connectors for loop-through wiring in multi-cabinet configurations.

The plywood enclosure is fitted with M8 inserts for wall bracket attachment and eyebolt suspension, broadening its use into permanent and semi-permanent installation roles. A 35mm pole-mount socket with a removable bung maintains a clean profile in install applications. The screw-free, cloth-backed perforated steel grille and black textured paint finish are specified for durability under rental-grade use.

The X12B functions without a processor as a full-range passive loudspeaker. However, integrating a system controller such as the Martin Audio DX0.5 unlocks precise EQ, crossover alignment, and limiter functions that maximize driver longevity and system performance. Rental companies and production houses with mixed amplifier inventories benefit from the X12B's straightforward passive operation and compatibility with a wide range of professional amplifier platforms.

Technical Specifications

Frequently Asked Questions

Does the X12B require a DSP controller to operate?

No. The X12B is a full-range passive two-way system and operates without a controller. However, pairing it with a Martin Audio DX0.5 or equivalent DSP controller enables EQ optimization, active crossover alignment, and limiter protection, which are recommended for professional deployments.

Which amplifiers are compatible with the X12B?

The X12B presents an 8Ω nominal impedance load and accepts NL4 (Speakon) connections, making it compatible with most professional power amplifiers from manufacturers such as Crown, Lab.gruppen, QSC, and similar. Always verify amplifier output power against the cabinet's rated power handling before deployment.

Can the X12B be flown or suspended?

Yes. The enclosure features M8 inserts that accept standard wall brackets and eyebolt suspension hardware, enabling flown and wall-mount configurations for permanent and semi-permanent installation.

What subwoofers pair with the X12B?

The X12B is designed to work within the BlacklineX Series ecosystem. Recommended subwoofer pairings include the X115B (15"), X118B (18"), and X218 (2x18"). Crossover and EQ alignment between the X12B and a BlacklineX subwoofer can be managed via the Martin Audio DX0.5 system controller or compatible iKON amplifiers. View the full range at creationnetworks.net.

Is the X12B suitable for a house of worship install?

Yes. Its controlled 80° x 50° dispersion, multiple mounting options, and clean aesthetic make it a practical choice for houses of worship, including main PA duty in small sanctuaries and as delay fills or front fills in larger auditoriums.

How does the rotatable horn work?

The HF horn assembly can be physically rotated by the operator to switch between portrait (vertical) and landscape (horizontal) coverage orientations. This allows the cabinet to be deployed in either orientation without changing the directional characteristics of the high-frequency section.

What is the warranty and support coverage?
