The Electro-Voice EVID 40 is a high-performance subwoofer engineered to deliver powerful, extended low-frequency reinforcement for professional distributed audio and background music systems in commercial and residential installations. Designed to complement the EVID series of surface-mount and in-ceiling loudspeakers, this compact yet potent enclosure houses a long-throw 12-inch woofer within a precisely tuned, ported cabinet. This design ensures efficient output of deep bass frequencies, filling in the lower octaves that smaller full-range speakers cannot reproduce, thereby creating a fuller, more impactful audio experience for music and multimedia content in spaces such as restaurants, retail stores, lounges, and home theaters.

Constructed with durability and aesthetic discretion in mind, the subwoofer features a rugged, moisture-resistant composite enclosure that can withstand the environmental conditions of commercial use. Its low-profile, trapezoidal shape and paintable, perforated steel grille allow it to blend seamlessly with interior decor when placed on the floor, mounted on a wall, or installed within custom cabinetry. Multiple integrated mounting points provide flexible installation options to suit various space constraints and acoustic requirements. The passive design allows for straightforward integration with existing amplifier channels, and it includes selectable input taps for compatibility with both low-impedance and 70V/100V constant-voltage systems commonly used in commercial audio.

Performance is characterized by its controlled, musical bass response, adding warmth and physical presence to any audio program without overwhelming the space or causing listener fatigue. The subwoofer's power handling and sensitivity are optimized to work efficiently with standard commercial amplifiers, ensuring reliable operation and sufficient output to balance with the broader speaker system. As a dedicated low-frequency extension module, the EVID 40 provides system integrators with a practical and effective tool to enhance overall sound quality, delivering the deep, resonant bass necessary for a complete and immersive listening experience in installed sound applications.
