Description
Download Manual The EVF-1152D/66 is a two-way point-source loudspeaker engineered for clear vocal intelligibility and controlled mid-far field coverage. It pairs a 15 in low-frequency driver with a 3 in titanium compression driver mounted on a rotatable 60 x 60 constant-directivity horn. The enclosure is compact and built to withstand demanding installed environments.
Key features include a rotatable 60 x 60 waveguide, a DH7N 3 in titanium compression driver, and a DVX3151A 15 in FEA-optimized woofer. The integrated passive crossover uses steep 24 dB/octave slopes and an acoustic crossover frequency of 1300 Hz. A dynamic protection circuit provides thermal protection for both driver sections.
Performance specifications deliver a wide usable bandwidth and high maximum SPL for its size. Frequency response is linear across the vocal range and extends low for a 15 in point-source enclosure, supporting a recommended high-pass at 45 Hz. Sensitivity and power handling are designed to provide 134 dB SPL (calculated) and continuous/program/peak ratings of 600 / 1200 / 2400 watts respectively.
Connectivity is via a Phoenix-style input panel capable of accommodating up to 10 AWG, with options for NL4-type or gland-nut covers for weatherized installations. The external jumper allows easy selection of passive or bi-amp operation. An optional 70.7/100 V transformer kit can be installed on the input panel for distributed systems.
This loudspeaker addresses a broad range of installed audio applications where controlled directivity and speech clarity are required. It is appropriate for mid-size performance spaces, houses of worship, and outdoor covered venues when combined with appropriate low-frequency support. Multiple horn patterns and EVF/EVH series compatibility enable system designers to scale coverage precisely.
Installation features include a trapezoidal, 13-ply birch cabinet treated with EVCoat for weather resistance and 22 M10 threaded suspension points for rigging. The grille options and fasteners are corrosion resistant to match wet or coastal environments within stated environmental limits. The cabinet finish and rigging options simplify integration into fixed-install projects.
Overall, the EVF-1152D/66 delivers focused 60 x 60 coverage, reliable thermal protection, and flexible rigging and input options in a compact two-way package. Its combination of a rotatable constant-directivity horn and FEA-optimized woofer maximizes speech intelligibility and musical clarity. The result is a dependable installed loudspeaker that reduces the need for multiple specialized models while providing precise coverage control.
