Product description

WorxAudio I/O-4 Indoor-Outdoor Speaker System

The WorxAudio® I/O-4 is a small-format, high-performance sound-reinforcement system designed for indoor and outdoor applications where music and speech reinforcement are specified. Its small size and unique appearance make it deal for restaurants, retail environments, bars, hotels, and other applications where high-quality music systems are specified. A standard mounting bracket provides flexible aiming and easy installation.

The versatile I/O-4 utilizes a dual-element array of high-output, 4-inch (101.6 mm) woofers. Its horn-loaded high-frequency waveguide is positioned between the two elements to ensure coherent and balanced high-frequency response. Polar lobing is controlled by this geometry and produces a properly aimed response at the crossover frequency.
