• 12-inch, two-way loudspeaker, with 90° x 55° constant directivity, rotatable waveguide
• Power rating: 300 W Continuous, (1200 Peak)
• Passive system: 95 dB, 126 dB maximum
• Gland nut cover and stainless steel grille on PI versions
• Optional high quality transformer and patented Automatic Saturation Control (ASC) preserve low end in 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 EVInnovation models (EVF, EVH, EVA).
The high frequency section of EVC loudspeakers comprises a single 1?-inch pure titanium dome compression driver directly coupled to a rotatable constant directivity waveguide that delivers 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 fourthorder Linkwitz Riley 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 15-mm plywood and finished with EVCoat for enhanced durability. The loudspeakers have been designed with multiple M10 rigging points as well as attachment points for an optional U-bracket or multi-mount style pan/tilt wall mount. All EVC series loudspeakers accept wire gauges up to 10 AWG. 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 TK150 audio transformer. Adding a TK150 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. This results in transformer and non-transformer EVC loudspeakers that sound virtually identical.

• 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 in 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 EVInnovation models (EVF, EVH, EVA). The EVC-1122/VI is a unique offering that is constructed in a variableintensity (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 1?-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.
