212.HC Platinum Hybrid Series Loudspeakers

The 212.HC is a compact dual 12" array system that provides excellent intelligibility, superb musical performance and high output capability. The 212.HC’s driver complement consists of a One Systems’ 12" woofer with a large-format 4" voice coil and a 12" woofer with a large-format, coaxially mounted compression driver. Utilizing these powerful 12" drivers in tandem at low and mid-frequencies provides high output capability while the large-format coaxially-mounted HF driver ensures beautifully detailed mids and highs with no horn coloration. This advanced design aligns the drivers producing point-source imaging. The result is a smooth, accurate, detailed-sounding speaker system with high power handling and excellent projection capability in an impressively small-sized direct-weather enclosure. All 212.HC's rigging components are made of 316 marine-grade stainless steel. Thanks to its range of suspension points, accessories and its 70-degree conical coverage pattern, the 212.HC can be installed horizontally or vertically for various applications. For any outdoor or general-purpose indoor applications, the 212.HC is an ideal solution for high-fidelity sound quality in large spaces or in high noise environments.
