Martin Audio SX212 Compact Dual-Driver Passive Subwoofer

Martin Audio SX212 is a compact dual-driver subwoofer designed for installed sound environments. It enables low frequency reinforcement for sound system operators, supporting full range loudspeaker systems. This makes it ideal for venues where extended low frequency output from a low profile enclosure is critical.

The subwoofer uses twin long throw drivers and a reflex loaded enclosure to extend low frequency performance while controlling air noise. Its enclosure construction and port design support integration with system processing and amplification for calibrated installations.

The SX212 is suited for permanent installations where reliable bass performance and discreet physical presence are required. It is commonly used in entertainment and public spaces that demand consistent low frequency output across varied program material.

Key Features

• Dual Driver Design: Uses two high efficiency low frequency drivers for extended bass response.
• Compact Enclosure: Low profile cabinet supports discreet installation in space limited venues.
• Reflex Porting: Large ports reduce air noise during high output operation.
• Integrated Rigging: Built in flying points support flexible mounting options.
• Durable Construction: Plywood enclosure with internal bracing limits panel resonance.
