One Systems 312.HC - 1200W 3 x 12-inch Passive 2-Way IP56-Rated Installation Loudspeaker with 70/100V Transformer in Black Finish

The One Systems 312.HC is a highly capable passive 2-way loudspeaker system specifically designed for high-output applications, featuring a sophisticated 3-element shaded vertical array that excels in delivering superior vocal intelligibility and high sound pressure levels. This loudspeaker is particularly well-suited for both marine environments and general-purpose indoor and outdoor settings. Constructed with marine-grade 316 stainless steel for all structural and rigging points, the 312.HC ensures exceptional durability and corrosion resistance, which is essential for installations in oceanfront and cruise ship applications. Non-structural metal components are coated with a newly developed marine-grade powder coat over 304-grade stainless steel, enhancing protection against harsh weather conditions. It is important to note that for marine environments, the included vent plugs must be installed to maintain optimal performance.

The 312.HC is designed for versatile applications, capable of performing in both direct weather outdoor installations and indoor environments where high vocal intelligibility and accuracy are crucial. Like all One Systems products, it not only offers excellent full-range fidelity but also prioritizes superior vocal reproduction. The system comprises three 12-inch direct radiator transducers arranged in a shaded array, with the top 12-inch element featuring a coaxial design that integrates a large-format compression driver. This configuration enables the 312.HC to deliver full bandwidth response while providing excellent vertical control, making it ideal for reverberant spaces such as gymnasiums, basketball arenas, and large multi-purpose venues.

The 312.HC's extended vertical control allows it to maintain consistent audio quality across the entire vocal range, making it suitable for outdoor spaces where clarity is paramount. Unlike many conventional high-output vocal range systems that rely on nested horns - often resulting in poor intelligibility and the characteristic "honky" sound - the 312.HC utilizes a unique design that enhances vocal clarity and time domain response. The enclosure is constructed from a copolymer optimized for high UV exposure, ensuring long-lasting performance in harsh environments. Additionally, the grille features a three-layer "rain shield" design, minimizing direct rain contact with the system's transducers and protecting internal components from moisture.

With an ingress protection rating of IEC 529 IP 45, the enclosure and grille can withstand solid object penetration and water jets from any direction. When the vent plugs are installed, the system is rated IP 56, further enhancing its suitability for outdoor applications. The input section features a 4-position barrier strip, and a weather cover is provided with an integral gland nut connector, rated NEMA 6P (IP 68), for secure outdoor connections. This gland nut accommodates cable diameters from 7mm to 12mm, making it compatible with most 2-conductor AWG 12 cable assemblies.

The 312.HC is equipped with 19 M10 rigging points for flexible mounting options, including suspension with the PM4/M pole mount system or the PT76/M pan and tilt system for flat surface mounting. An optional U-bracket, the 312HC-U/M, is also available for added versatility. With a frequency response of 75Hz to 16kHz and passive crossover frequencies set at 400Hz and 1800Hz, the One Systems 312.HC ensures clear and powerful sound reproduction. The system sensitivity is an impressive 99 dB (1 Watt / 1 Meter), and it can handle up to 1200 watts continuous, 2400 watts program, and 4800 watts peak power, making it a top choice for various entertainment and sports venues. Weighing 93.5 lbs and measuring 43.3 x 14.5 x 16.3 inches, the One Systems 312.HC combines powerful audio performance with robust construction, providing a highly effective solution for demanding audio environments.
