Product Overview

  • 97 dB sensitivity, 129 dB maximum SPL ? System rating: 350 W Continuous, 1400 W Peak)
  • Recommended frequency range: 30 Hz to 135 Hz
  • Designed to work with EVC 8-, 12-, and 15-inch systems
  • Optional high quality transformer and patented Automatic Saturation Control (ASC) enable subwoofer operation on dedicated 70V/100V lines
The EVC-1181S subwoofer comprises a single 18" lowfrequency transducer in an optimally vented enclosure. It was created to complement the 8-, 12-, and 15-inch full range EVC systems, including the EVC-1122/VI Variable Intensity loudspeaker. Like other EVC models, the EVC-1181S subwoofer was designed and voiced to work in systems that use other EV-Innovation loudspeakers (EVU, EVF, EVH, EVA). The EVC-1181S does not have an internal passive crossover, it requires a suitable active low pass filter and 4th-order Butterworth system high pass filter for proper operation.

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 EV-1181S subwoofer was designed for floor mounting or suspension from its multiple M10 rigging points. 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 TK-150 audio transformer. Adding a TK-150 to the EVC-1181S 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 the ability to drive multiple EVC-1181S subwoofers from a single dedicated 70V/100V drive channel.connectors or be adapted for weather-proof single or dual gland nuts when fitted with an accessory input adapter plate.

The input panel should include a landing pad and appropriate electrical connections on the inside of the loudspeaker cabinet so that the installer can mount and connect a high-quality audio transformer in series with the direct low-impedance connection to the loudspeaker dividing network. When the transformer is installed, the input circuit network shall be augmented with a high-pass filter with a current-dependent corner frequency in order to preserve the full bass response of the loudspeaker while protecting system amplifiers from the drop in load impedance that commonly occurs when audio transformers are driven into saturation.
