The Electro-Voice EVF-1151S is a high-power, 15-inch front-loaded bass element (subwoofer) designed specifically for fixed installation sound systems. It serves as a low-frequency reinforcement unit tailored to match the footprint and aesthetics of the Electro-Voice EVF Series full-range loudspeakers, enabling clean horizontal or vertical cluster configurations.

Core Specifications

The primary technical attributes of the EVF-1151S, as verified by official Electro-Voice Product Documentation, include:

• Transducer: Features a high-excursion EVS15SB 15″ woofer engineered using Finite Element Analysis (FEA) to minimize distortion.
• Power Handling: Supports 400 Watts Continuous / 800 Watts Program / 1600 Watts Peak.
• Acoustic Performance: Delivers a maximum calculated SPL of 135 dB (Half-Space) with a high sensitivity of 103 dB (1 W/1 m) (Note: Anechoic/full-space calculations specify 99 dB sensitivity / 131 dB Max SPL).
• Frequency Range: Offers an operational range of 46 Hz to 124 Hz (-10 dB) and a flat response of 67 Hz to 95 Hz (-3 dB).
• Impedance: Evaluated at a 4Ω nominal impedance.
• Enclosure: Built from durable 13-ply weather-resistant birch plywood in a trapezoidal form factor, weighing roughly 28.4 kg (62.6 lbs).
