Electro-Voice EVC-1181S Subwoofer System - 350 W RMS - Black

The Electro-Voice EVC-1181S Subwoofer System is engineered for professional sound reinforcement, delivering deep, authoritative bass with precise control. Built to pair seamlessly with the EVC 8-, 12-, and 15-inch systems, this subwoofer brings low-end impact to clubs, theaters, houses of worship, and touring setups without sacrificing clarity in the midrange and vocal frequencies. Featuring a robust 350 W continuous (1400 W peak) rating, the EVC-1181S is designed to meet demanding on-stage and on-site requirements, delivering consistent performance across a wide range of environments. With a sensitive 97 dB and a maximum SPL capable of delivering up to 129 dB, this subwoofer can punch through dense mixes and deliver the kind of bass that moves audiences without overwhelming the rest of the system. The EVC-1181S also incorporates advanced options such as a high-quality transformer and the patented Automatic Saturation Control (ASC), enabling reliable subwoofer operation even under dynamic power conditions. In a compact, black enclosure that’s built for road-ready durability, this subwoofer offers flexible installation options, whether you’re stacking in a rig, flying with others, or placing in a front-of-house position to anchor your low-end performance.

• Powerful low-end performance with 350 W continuous (1400 W peak) ensures tight, dynamic bass that supports the whole mix and drives impactful live sound.
• High sensitivity and SPL capability—97 dB sensitivity and up to 129 dB max SPL—so even modest amplifier power yields strong bass presence in medium to large venues.
• Wide low-frequency extension with a recommended frequency range from 30 Hz to 135 Hz, delivering deep kick drum, bass guitar, and synthesizer bass with natural articulation.
• Versatile compatibility with Electro-Voice EVC 8-, 12-, and 15-inch systems for scalable rig configurations, whether you’re building a compact two-sub setup or a larger multi-sub array.
• Advanced control options, including optional high-quality transformer and patented Automatic Saturation Control (ASC) for stable, distortion-free operation across varying signal levels.

How to install Electro-Voice EVC-1181S Subwoofer System

• Plan your layout: Determine the number and placement of subwoofers to achieve the desired bass coverage for the venue. The EVC-1181S is designed for flexible positioning, whether in front-of-house stacks, on-stage setups, or ground-stacked configurations with compatible EVC enclosures.
• Prepare connections: Use high-quality speaker cables to connect the subwoofer to the compatible amplifier channel(s). If you are using ASC or an optional transformer, ensure those features are configured according to the system’s manual and the venue’s power requirements.
• Position for performance: Place the subwoofer to optimize room acoustics and bass response. Common strategies include corner placement for enhanced low-frequency reinforcement or a symmetric pair in front-of-house for balanced coverage. Avoid obstructing airflow and allow space for cooling if the enclosure carries high power loads during extended performances.
• Integrate with the main system: Align the subwoofer with the EVC 8-, 12-, or 15-inch loudspeakers by setting crossover points, phase, and level to achieve a cohesive, musical bass foundation. Start with a conservative crossover and level, then adjust while monitoring the overall mix for clarity and balance.
• Test and calibrate: Run the system through typical program material, listen for any room-induced anomalies, and refine ASC settings (if used) along with the transformer configuration. Verify that the subwoofer maintains clean bass without introducing distortion, compression, or unwanted resonance in the venue.
