The EAW SB150zP Black is a 700W, 15-inch passive subwoofer designed for professional installations where compact size and powerful bass output are crucial. Part of EAW’s premium SB series, this subwoofer is engineered to deliver outstanding low-frequency performance and exceptional reliability in demanding environments. The SB150zP Black is ideal for spaces where the impact of a 15-inch driver is desired but where larger subwoofers would be impractical. It is commonly used in applications such as small houses of worship, A/V systems, hotel ballrooms, meeting rooms, exhibit areas, and f/x reinforcement, as well as cruise ships, cinemas, TV studios, and small retail spaces. The versatile subwoofer’s ability to provide high output while maintaining a compact design makes it a perfect choice for permanent installations requiring deep, clean bass.

The SB150zP Black features a 15-inch cone driver housed in a vented, optimally tuned enclosure. The design allows for high output and exceptional bass performance with minimal distortion. The subwoofer has a frequency range from 34 Hz to 145 Hz, providing solid, low-end reproduction that complements full-range loudspeakers in a variety of sound reinforcement systems. With its 700W capacity, the SB150zP Black is capable of delivering impressive sound pressure levels with an average SPL of 121 dB in whole space and 127 dB in half space. It also achieves a peak SPL of 127 dB in whole space and 133 dB in half space, making it suitable for large or acoustically challenging environments where high-impact bass is needed.

Designed for use with digital signal processing (DSP), the SB150zP Black optimizes the low-frequency response for better clarity and punch. EAW recommends using the MX Series processors to handle the necessary crossover and equalization, ensuring that the subwoofer performs at its best in every installation. The system also includes a high-pass filter at 30 Hz with a 12 dB/octave Butterworth slope, which helps prevent overextension of the low-frequency driver and ensures better control over the bass frequencies. The subwoofer’s impedance is nominally 8 ohms, with a minimum of 6.9 ohms at 40 Hz, ensuring compatibility with most amplifiers in professional audio systems.

The SB150zP Black is built to withstand the rigors of permanent installations. Its enclosure is constructed from Baltic birch plywood, which provides durability, strength, and resonance control for improved sound quality. The subwoofer is finished with a wear-resistant textured black paint, making it not only functional but also visually discreet and professional in appearance. A vinyl-coated perforated steel grille protects the 15-inch driver from damage while allowing for optimal sound dispersion. With its compact dimensions (24.62 x 19.68 x 19 inches) and a weight of 72 lbs, the SB150zP Black is easy to integrate into a variety of installation spaces without compromising on performance or sound quality.
