Description
The EVF-1122D/66-FGB is a fully-weatherized 12 in arrayable two-way point-source loudspeaker designed for outdoor and exposed-install environments. It combines a DVX3121A 12 in low-frequency driver and a DH7N 3 in titanium compression driver on a rotatable constant-directivity waveguide. The enclosure is fiberglass-coated birch engineered to resist extreme weather and provide long-term reliability.
The loudspeaker features a rotatable 60 x 60 coverage pattern and a high-output titanium compression driver for clear high-frequency response. A 24 dB/octave passive crossover with tailored equalization preserves vocal clarity and ensures smooth off-axis response. The system supports both passive and active operation via an externally accessible jumper for installation flexibility.
Performance is focused on intelligibility and SPL capability. The EVF-1122D/66-FGB has an axial sensitivity of 97 dB and a calculated maximum SPL of 131 dB. Frequency response is specified at -3 dB from 118 Hz to 18 kHz and -10 dB from 66 Hz to 21 kHz, with a recommended high-pass at 65 Hz and a passive crossover at 1300 Hz.
Connectivity and installation options include a standard Phoenix-style input connector and options for dual NL4 or gland-nut weatherized plates. An optional 70.7/100 V transformer kit can be mounted on the input panel for distributed-line systems. Rigging hardware and enclosure geometry allow vertical and horizontal arrays using EVF and EVH series enclosures.
The EVF-1122D/66-FGB is suitable for fixed installs such as stadium perimeters, amphitheaters, theme parks, and waterfront venues where exposure to the elements is expected. It can be combined with complementary low-frequency cabinets and subwoofers to achieve larger systems and extended low-end performance. The rotatable waveguide and arrayable trapezoidal enclosure simplify coverage planning across varied venues.
Installation is simplified by durable construction and accessible service points. The fiberglass-coated birch enclosure and stainless-steel grille provide corrosion resistance while internal crossover protection and robust transducer design support sustained high-SPL operation. The EVF-1122D/66-FGB delivers predictable acoustic behavior and reduced inventory complexity for integrators specifying weather-resistant arrayable systems.
