SPL Show SS 12 D2 12-Inch Dual Voice Coil Subwoofer

The Hertz SPL Show SS 12 D2 is a 12-inch (30 cm) subwoofer engineered for extreme sound pressure level (SPL) events and demanding audio installations. It boasts a robust 1000 Watts of continuous RMS power handling and can surge to 2000 Watts of peak power. The subwoofer features a substantial 75 mm (3 inch) dual voice coil, configured as 2 + 2 Ohms, which is developed in a 4-layer configuration on a support with venting holes for optimal heat dissipation. This advanced thermal management ensures reliability during prolonged high-volume use. The cone material is a specially designed non-pressed paper with added cotton fiber, offering a balance of stiffness and damping for maximum sensitivity and precise low-frequency reproduction. The SPL Show SS 12 D2 also incorporates a double-layer spider with a progressive profile for consistent performance and a large ferrite magnet assembly. Its mechanical excursion capabilities are highlighted by an Xmax of 15.4 mm and an Xmech of 20.7 mm, allowing for significant cone movement to produce impactful bass without distortion. Installation dimensions include a mounting depth of 184 mm and an outer diameter of 320 mm, with a cutout diameter of 283 mm. The subwoofer is suitable for both sealed and vented enclosure designs, with recommended sealed box volume at 35 liters for a 47 Hz cutoff and reflex box volume at 55 liters for a 51 Hz tuning frequency.
