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, EVA, and EVU). The high frequency section of EVC loudspeakers comprises a single 1¼-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 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 15-mm plywood and finished with EVCoat for enhanced durability. The loudspeakers have been designed with multiple M10 suspension 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 (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. An EVC loudspeaker with a transformer installed sounds virtually identical to the same model without a transformer.
