Durable Construction for Long-Term Reliability
Built for durability, the EVC-1181S-W features a 15-mm plywood enclosure finished with Electro-Voice’s EVCoat for added protection. The sturdy cabinet is designed to withstand continuous use in indoor fixed installations, while the clean white finish blends seamlessly into any venue's architecture. This combination of performance and durability makes the subwoofer an excellent choice for permanent installations.

Flexible Mounting Options for Easy Installation
Designed with versatility in mind, the EVC-1181S-W includes multiple M10 suspension points for secure mounting in various configurations.

Optional Transformer for Distributed Audio Systems
The EVC-1181S-W supports the optional TK-150 transformer for 70V/100V operation, making it ideal for distributed audio applications. With Electro-Voice’s patented Automatic Saturation Compensation (ASC) technology, the subwoofer maintains its low-end clarity and efficiency even when multiple units are connected in parallel. This ensures reliable bass performance across large-scale systems without signal loss.

Optimized Active Filtering for Superior Sound Quality
To achieve its full performance potential, the EVC-1181S-W requires an external active low-pass filter and fourth-order Butterworth high-pass filter. This design approach ensures the subwoofer delivers precise, clean, and optimized bass response, making it an essential part of any full-range audio system.
