Martin Audio SX212 – 2x12" Passive Direct-Radiating Subwoofer (Black)

Product Overview

The Martin Audio SX212 is a compact, dual-driver, direct-radiating passive subwoofer engineered for commercial install and live sound applications requiring LF extension and impact from a low-profile, unobtrusive enclosure. Twin high-efficiency 12" (300mm) drivers with 3" (75mm) voice coils deliver significantly higher LF output than single-driver 12" alternatives while maintaining a compact enclosure footprint. Optimally sized reflex ports minimise air noise at operating levels. Integrated flying points and black or white finish options give system designers deployment and aesthetic flexibility across diverse commercial environments.

Product Description

The SX212 occupies the dual-driver 12" position in the Martin Audio SX Series direct-radiating passive subwoofer range, providing materially greater LF output and headroom than the single-driver SX112 while remaining within a compact, low-profile enclosure that suits permanent commercial installs where visual impact must be minimised. Twin 12" (300mm) long-throw drivers each feature 3" (75mm) voice coils and water-resistant cones, extending deployment options to moderately exposed environments. Optimally sized reflex ports are tuned to minimise turbulent air noise — critical for commercial listening environments including museums, convention centres, and hospitality venues with low ambient noise floors. The compact, low-profile styling of the SX212 enclosure reduces visual intrusion in permanent install settings where aesthetics are a consideration. Integrated flying points support overhead rigging in addition to floor placement, and units can be stacked for additional LF coupling where system requirements demand elevated output. The SX212 is the appropriate selection for integrators who need dual-12" direct-radiating passive subwoofer performance in a compact form, particularly where 18" subwoofer dimensions are architecturally impractical.

Frequently Asked Questions

Is the SX212 a passive or powered subwoofer?

The SX212 is a passive subwoofer requiring an external amplifier. A DSP processor is recommended for crossover and system alignment.

How does the SX212 differ from the SX112?

The SX212 adds a second 12" driver for significantly higher LF output and headroom compared to the single-driver SX112, while maintaining a compact enclosure profile.

Can the SX212 be flown or stacked?

Yes. Integrated flying points support overhead rigging. Units can also be stacked for additional LF coupling.

Is a white version available?

Yes. The SX212-W is the white finish variant for colour-matched commercial installs.

Is the SX212 suitable for outdoor installation?

Water-resistant cones extend deployment to moderately exposed environments. For fully weatherised outdoor installs, consult Martin Audio's CDD-WR series.
