Electro-Voice EVC-1181S-PI 18" Weatherized Subwoofer

The Electro-Voice EVC-1181S-PI Weatherized Subwoofer comprises a single 18" low frequency transducer in an optimally vented enclosure. It was created to complement the 8", 12", and 15" full range EVC systems, including the EVC-1122/VI Variable Intensity loudspeaker.

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 points. 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-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 over a 70V/100V drive channel, while still delivering full, rich bass response.
