Martin Audio SX112 – 12" Passive Direct-Radiating Subwoofer (Black)

Product Overview

The Martin Audio SX112 is an ultra-compact, single-driver, direct-radiating passive subwoofer designed to extend the bandwidth and increase the headroom of full-range loudspeaker systems in commercial install and live sound applications. A high-efficiency 12" (300mm) long-throw driver with a 3" (75mm) voice coil delivers meaningful LF reinforcement from a compact enclosure suited to space-constrained permanent installations. The water-resistant cone and integrated flying points expand deployment options across both indoor and moderately exposed locations. Available in black and white (SX112-W).

Product Description

The SX112 occupies the standard direct-radiating passive subwoofer position in the Martin Audio SX Series, providing greater LF output than slimline 10" alternatives in a still-compact enclosure footprint. The 12" (300mm) long-throw driver features a 3" (75mm) voice coil for high power handling and a water-resistant cone that extends deployment options beyond climate-controlled indoor environments. Generously sized reflex ports are optimised for low air noise at operating levels, maintaining acoustic transparency in commercial listening environments. Integrated flying points support overhead rigging configurations in addition to standard floor placement, giving integrators flexibility across diverse installation types including concert halls, nightclubs, convention centres, and houses of worship. The compact, low-profile enclosure styling minimises visual impact in permanent install contexts. The SX112 is the appropriate selection where a slimline 10" passive subwoofer is acoustically insufficient and a full-size 18" subwoofer is physically impractical or excessive. Both black and white finish options ensure colour-matched integration in varied architectural environments.

Frequently Asked Questions

Is the SX112 a passive or powered subwoofer?

The SX112 is a passive subwoofer requiring an external power amplifier. A DSP processor is recommended for system alignment and crossover management.

How does the SX112 differ from the SX110 slimline?

The SX112 uses a larger 12" driver in a standard direct-radiating enclosure, delivering greater LF output and lower frequency extension than the slimline SX110. The SX110 has a shallower enclosure depth for space-constrained installs.

Is the SX112 suitable for outdoor installation?

The water-resistant cone extends the SX112's deployment range to moderately exposed environments. For fully weatherised outdoor installs, consult Martin Audio's CDD-WR series.

Can the SX112 be flown?

Yes. Integrated flying points support overhead rigging configurations.

Is a white version available?

Yes. The SX112-W is the white finish variant.
