12" speaker, vari-intense indoor

  • 12-inch two-way loudspeaker with asymmetrical horn uniformly covers a defined rectangular area
  • Power rating: 300 W Continuous, (1200 W Peak)
  • Optional high quality transformer and patented Automatic Saturation Control (ASC) preserve low end over 70V/100V lines

EVC loudspeakers from Electro-Voice are two-way systems that can be used in a broad range of applications where wide bandwidth, vertical and horizontal directivity control, and high efficiency are required in a compact, cost-effective package. EVC loudspeakers are voiced to complement other EV-Innovation models (EVF, EVH, and EVA). The EVC-1122/VI is a unique offering that is constructed in a variable intensity (VI) configuration. In a variable intensity loudspeaker, the downward angle of the front-facing woofer and the asymmetrical wave guide work together to evenly cover a clearly defined, rectangular audience area with a single loudspeaker system. The size of the coverage area is determined by the mounting height and the vertical mounting angle of the loudspeaker. The advantage of the VI approach is that there is reduced variation in sound level from the front to the back of the audience, compared to typical point source solutions. In most situations, the change is so gradual that the sound level will seem almost constant as you walk the coverage pattern. The EVC-1122/VI delivers clear, articulate speech reproduction but, in addition, is an excellent choice for foreground music applications. It can be used as a stand-alone full-range system, or as the mid-bass/high-frequency box in multi-way loudspeaker systems when used with the complementary EVC-1181S 18" subwoofer.

The high frequency section of the EVC 1122/VI loudspeaker comprises a single 1¼-inch pure titanium dome compression driver directly coupled to a compound waveguide that combines long-throw and short-throw behavior in a single acoustical device. This unique waveguide creates uniform pattern control and smooth, linear response.

The low frequency section employs a high-output woofer that was developed using state-of-the-art, computer-aided optimization to provide low distortion, high efficiency, and maximum intelligibility at high sound pressure levels. The passive crossover implements a modified fourth-order design with slopes of 24 dB per octave for smooth off-axis response and improved definition through the critical vocal range.

The EVC series is an extremely cost effective solution for many fixed-install applications. The enclosures are constructed of weather-resistant plywood and finished with EVCoat for enhanced durability. The EVC-1122/VI has been designed with multiple M10 suspension points as well as attachment points for an optional U-bracket that can be mounted to the ceiling or the wall behind the loudspeaker. All EVC series loudspeakers accept wire gauges up to 10 AWG (6 mm). The input panel also accepts optional covers with NL4-type connectors or weatherized gland-nuts.

For 70V/100V operation, the input panel has an internal landing pad for mounting EV's high-quality TK-150 audio transformer. Adding a TK-150 to the EVC input panel engages EV's patented Automatic Saturation Compensation (ASC), which preserves low frequency performance while presenting a stable load to the amplifier regardless of how many loudspeakers are connected in parallel, as long as the total power draw does not exceed the amplifier capacity. The TK-150 is flat to ±1 dB from 35 Hz to 20 kHz, so it is almost impossible to tell whether an EVC loudspeaker has a transformer installed or not.
