112.HSB-WHT Platinum Hybrid Series Subwoofers

The One Systems 112.HSB is a premium-class 12-inch subwoofer solution that’s suitable for indoor and outdoor professional audio applications. The 112.HSB provides additional low-frequency output when used with all variants of One Systems 104, 106, 108, 208, 112 and 212 full-range speakers.

The 112.HSB’s 12-inch transducer is equipped with a 4-inch voice coil. Its patented 12I/O woofer utilizes a voice coil that’s wound on the inside of the coil’s support structure (U.S. Patent #8,543,856 B2). This design provides high magnetic system displacement and increased thermal transfer that reduces power compression and ensures higher reliability.

The 112.HSB utilizes a thick-walled injection molded enclosure designed to handle direct weather applications. The 112.HSB’s input section features a weather cover equipped with an IP 68 rated gland nut and a 4-position barrier strip with stainless steel hardware.
