Electro-Voice EVC-1122-VIB 12" Vari-Intense Indoor Passive PA Speaker (Black)

Designed for Uniform Coverage in Rectangular Spaces
The Electro-Voice EVC-1122-VIB is a versatile 12-inch two-way passive PA speaker designed to deliver even sound distribution across defined rectangular audience areas. Ideal for indoor installations where both music and speech clarity are critical, this speaker’s variable intensity (VI) design ensures consistent audio levels from the front to the back of the room. Whether used in houses of worship, lecture halls, or entertainment spaces, the EVC-1122-VIB offers an efficient, cost-effective audio solution.

Variable Intensity Design Provides Consistent Sound Levels
Unlike traditional loudspeakers, the EVC-1122-VIB’s asymmetrical horn and downward-angled woofer work together to evenly cover a defined rectangular area. This unique variable intensity design reduces variations in sound level, ensuring smooth, gradual audio distribution. The result is a consistent listening experience where volume levels remain near-constant throughout the coverage area, improving both music playback and speech intelligibility.

High-Frequency Precision with Advanced Waveguide Technology
The high-frequency section features a 1.25-inch pure titanium dome compression driver paired with a specialized compound waveguide. This innovative waveguide combines long-throw and short-throw capabilities into a single design, delivering smooth, controlled high-frequency dispersion. The precision waveguide ensures uniform pattern control and clear, natural sound reproduction, making the speaker ideal for spaces requiring intelligible speech and detailed music playback.

Powerful Low Frequency Performance for Full-Range Sound
The EVC-1122-VIB is equipped with a high-output 12-inch woofer, optimized for minimal distortion and maximum efficiency. Using state-of-the-art computer-aided design, the woofer provides robust low-frequency performance with exceptional clarity. Paired with a modified fourth-order passive crossover, this design ensures smooth off-axis response and improved definition across the critical vocal range.

Flexible Mounting Options for Any Installation
The EVC-1122-VIB offers multiple M10 suspension points and mounting options for easy integration into various spaces. Compatible with an optional U-bracket, the speaker can be mounted to walls or ceilings to suit unique installation needs. Its compact, durable enclosure seamlessly blends into any environment while delivering professional-grade sound.

Durable Construction Ensures Long-Lasting Performance
Constructed from weather-resistant plywood and finished with EVCoat, the EVC-1122-VIB is built to withstand the demands of fixed installations. This rugged design ensures reliability and longevity in high-use environments, making it an ideal choice for professional applications that require consistent audio performance over time.

Optional Transformer for 70V/100V Systems with ASC
The EVC-1122-VIB is compatible with the optional TK-150 audio transformer for 70V/100V distributed systems. The transformer integrates Electro-Voice’s patented Automatic Saturation Compensation (ASC), preserving low-frequency performance and providing a stable load to the amplifier. This ensures high-quality sound regardless of how many speakers are connected in parallel, making the EVC-1122-VIB a flexible solution for larger installations.
