The Electro-Voice® EVF-1122D 600W (passive) loudspeaker offers a two-way front-load design featuring the DVX3121A with forced air cooling, Electro-Voice's latest 12" woofer innovation, accompanied by the DH7N high-frequency compression driver mounted on a new, fully rotatable 12" x 12" waveguide (available in 60° x 40°, 60° x 60°, 90° x 40°, 90° x 60°, 90° x 90°, and 120° x 60° patterns). System is capable of passive or bi-amp operation. Available in black or white, with a choice of three finishes: EVCoat™ (interior use), PI (indirect weather exposure), and FG (fiberglass, for direct weather exposure).
The EVF-1122D full-range systems substitute the DH7N large-format, 3-inch-diaphragm, 75W compression driver and 500-W woofers—DVX3121A 12-inch in the EVF-1122D. While the continuous maximum output of the "D" systems is unchanged, their dynamic performance is improved. The higher power capacity of the woofers and, especially, the compression driver allow the systems to produce higher sound levels at a given level of distortion. The higher power capacity also results in less power compression, where attempts to increase the sound level are not fully realized because as the voice coils heat up their impedance rises, reducing the acoustic efficiency of the speaker system.
