One Systems 104.STH - 40W 4.5-inch Passive 2-Way IP56-Rated Installation Loudspeaker with 70/100V Transformer in Gray Finish

The One Systems 104.STH is a versatile and robust passive 2-way loudspeaker system designed to deliver exceptional audio performance in general-purpose inland environments. With its IP56 rating, the 104.STH is engineered to withstand various weather conditions, making it suitable for outdoor installations where durability is paramount. The speaker features a sleek gray finish that is UV-stabilized, ensuring it maintains its aesthetic appeal over time, even in challenging outdoor settings.

This loudspeaker system utilizes high-quality stainless steel for all rigging points, providing reliable support when used with optional One Systems rigging accessories such as the PM2/M pole mount system or the PT-10/M pan/tilt bracket. The included U-bracket and grille are crafted from structural steel, finished with a dual-layer zinc-rich powder coating that enhances their durability and corrosion resistance, ensuring long-lasting performance in demanding environments.

The 104.STH offers flexible configuration options with its configurable Hi Z or Lo Z mode. The Hi Z mode is equipped with a wide bandwidth 50-watt autoformer that provides input taps at 50 Watts, 25 Watts, and 12.5 Watts, allowing for seamless integration into various audio setups. In Lo Z mode, the speaker operates at 8-ohms, providing a straightforward connection for standard audio systems. Notably, the configuration scheme is designed without switches, enhancing system reliability and performance.

This two-way speaker design boasts a wide coverage pattern of 110 degrees by 80 degrees, making it ideal for short throw applications and near-field sound reinforcement. The elliptical waveguide optimally loads the high-frequency driver, ensuring clear and crisp sound reproduction. The 4.5-inch low-frequency component, featuring a large ferrite magnet and a treated paper cone, excels at vocal reinforcement, delivering high sensitivity and superb audio fidelity.

The 104.STH includes four M5 rigging points located on the back of the enclosure, which can be utilized with compatible mounting options like the PT-10/M pan/tilt bracket or the PM2-M pole mount system. The injection-molded cabinet design is crafted from a high-impact copolymer material that demonstrates superior weather resistance, ensuring that the speaker performs reliably in outdoor conditions.

Additional features of the 104.STH include a three-layer "rain shield" grille that protects the speaker's components from moisture and an input weather cover equipped with a waterproof gland nut. The overall ingress protection rating of IP56 confirms that this speaker is well-suited for various applications, from outdoor installations to demanding indoor environments.
