The One Systems 104.STH™ is a compact-sized 4.5" two-way loudspeaker well-suited for general-purpose indoor applications as well as for inland environments outdoors. The system’s direct-radiating transducers include a 4.5" woofer with a 1-inch voice coil and ferrite magnet. The HF section has a 1" HQ tweeter with an elliptically-shaped Low-Q 110o x 80o waveguide. The 104.STH is installer-configurable for Lo-Z (8 ohm) or Hi-Z (70.7 / 100 volt) operation using two input barrier strips without switches that could limit the system’s reliability. Hi-Z taps at 50, 25 and 12.5 watts at 70.7 or 100 volts.
The 104/STH uses proven One Systems weatherproofing included a robust thick-walled enclosure, specially-built components and use of stainless steel suspension hardware to ensure long useful life. The 104.STH U-Bracket is made of structural steel, with a dual-layer, zinc-rich powder coat finish. Wall and pole mount, pan / tilt brackets are available for added mounting flexibility.
