The EAW SB120zP is a high-performance, 450W passive 12-inch subwoofer designed to meet the demanding requirements of professional installations. This compact subwoofer is specifically engineered for permanent installation in applications where space is limited but impactful low-frequency output is still desired. With its 12-inch driver and optimally tuned vented enclosure, the SB120zP delivers deep, accurate bass in a small form factor, making it ideal for high-quality multimedia systems, A/V installations, and a wide range of commercial applications. Whether used in meeting rooms, classrooms, TV studios, or retail spaces, the SB120zP provides exceptional sonic performance with 360-degree coverage for uniform bass distribution across the venue.

As part of EAW’s premium SB subwoofer line, the SB120zP features a high-output design that ensures reliable performance and high fidelity even in demanding environments. The subwoofer’s single 12-inch cone driver, coupled with a vented enclosure, provides powerful, punchy bass that complements most full-range loudspeakers. This makes it a versatile option for a variety of spaces, including exhibit areas, f/x reinforcement, cruise ships, and restaurants. Its compact size allows for discreet installation without sacrificing low-frequency impact, making it a great choice for smaller venues or spaces with aesthetic constraints.

To optimize the low-frequency response, the SB120zP is designed for use with sophisticated digital signal processing (DSP). EAW recommends using the MX Series processors to handle crossover and equalization, ensuring that the subwoofer delivers precise, consistent performance across its operating range. With an operating range from 44 Hz to 152 Hz, the SB120zP provides deep bass extension while maintaining clarity and accuracy. The subwoofer is engineered with EAW’s signature acoustical design, ensuring superior output, reliability, and sound quality even in challenging acoustic environments.

The SB120zP delivers an impressive SPL output, with an average SPL of 119 dB in whole space and 125 dB in half space. The subwoofer achieves a peak SPL of 125 dB in whole space and 131 dB in half space, providing ample output for applications that require high-impact bass in smaller spaces. The enclosure is constructed from Baltic birch plywood, offering durability and structural integrity, and it is finished with wear-resistant textured black paint for a professional, long-lasting appearance. The vinyl-coated perforated steel grille protects the driver while allowing for optimal sound dispersion.

The SB120zP is designed to be easy to integrate into a variety of professional sound systems. Its 360-degree coverage pattern ensures even bass distribution throughout the space, making it ideal for multi-room installations or larger venues. The subwoofer’s nominal impedance is 8 ohms, and it features a high-pass filter at 40 Hz with a 12 dB/octave Butterworth slope. With its robust construction, high-performance capabilities, and flexibility in installation, the SB120zP provides the ideal solution for applications requiring compact yet powerful sub-bass reproduction.
