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.
Compact, Versatile Loudspeaker that Delivers Indoors or Outdoors
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.
Key features:
- Compact profile
- High sensitivity
- Indoor/outdoor weather resistant
- Two-element low-frequency array
- Multitap matching transformer standard
- Neodymium-based high-frequency driver
