Electro-Voice EVC-1181S 18-Inch Passive Subwoofer

The EVC-1181S passive subwoofer from Electro-Voice comprises a single 18" low frequency transducer in an optimally vented enclosure, and offers an affordable solution for many fixed-install applications. Designed to complement the 8-, 12-, and 15-inch full range EVC systems, including the EVC-1122/VI Variable Intensity loudspeaker, 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 from Electro-Voice is constructed of 15-mm plywood enclosures and finished with EVCoat for enhanced durability.

About Passive Speakers at Sound Productions

Enjoy full flexibility and customization with passive speakers from Sound Productions! All speakers need a sort of amplifier to function; while powered speakers come with amplifiers built-in, passive speakers need external gear to be connected, including external amplifiers or stereo receivers, speaker cables, and possibly an outboard crossover or other signal processing gear.

Personalization is the hallmark of passive speakers. Mix-and-match components to fit the highly-specific needs of any given project. Scale to fit a larger space or add surround sound as your audio needs change. Because there’s more space inside passive speaker housing, passive speakers can accommodate larger drivers, resulting in a more pristine, accurate sound reproduction where it’s needed most, such as concert halls, entertainment venues, or special events.

Passive speakers are ideal for when you need flexibility and customization options. Often this means professional applications, such as venues where the sound system needs to be scalable and versatile, or for audio projects that require the most accurate and reliable sound reproduction.
