Martin Audio SX210 Dual 10 Inch Passive Slimline Subwoofer - Black

Martin Audio SX210 Dual 10 Inch Passive Slimline Subwoofer

The Martin Audio SX210 passive slimline subwoofer combines two 10" long-excursion drivers in a compact enclosure for professional low-frequency reinforcement where space and visual impact matter. This umbrella listing includes both Black and White finishes, providing the same acoustic platform for live sound, installed AV, hospitality, corporate, and house-of-worship applications.

The low-profile cabinet can operate individually, stack with additional SX210 enclosures, or fly from its integrated M8 inserts. Large reflex ports help control air noise, while two rear bar handles simplify positioning and transport. The Black finish suits conventional production environments, while the White option supports installations where loudspeakers need to blend into lighter architectural interiors.

Current Martin Audio specifications rate the SX210 at 400 W AES and 1600 W peak with 4-ohm nominal impedance. Its 50 Hz to 150 Hz operating range, omnidirectional low-frequency dispersion, active crossover requirements, and birch/poplar plywood enclosure make it suitable for professionally amplified systems using appropriate DSP and amplification.
