PreSonus I/O-4 2-Way Small Format Indoor/Outdoor 8 Ohm 100V Passive Loudspeaker System - Pair (Discontinued)

The Presonus 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 ideal 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.

The loudspeaker can be easily configured for a standard low-impedance direct input and features a standard multitap input transformer that is switchable between 5, 12, 15, and 50 watts of input power.
