The EAW SB528zP-WP is a 1400W, dual 18-inch passive subwoofer engineered for high-output performance in demanding professional installations. Part of EAW's premium SB series, this large-format subwoofer is designed for permanent installation where deep, impactful bass is required in both compact and expansive venues. With its robust construction, the SB528zP-WP is ideal for use in large houses of worship, auditoriums, theaters, cinemas, and large dance clubs. The subwoofer features dual 18-inch drivers housed in a vented, optimally tuned enclosure, delivering extremely low-frequency response with precision and clarity. Whether for f/x reinforcement in cinemas or bass-heavy applications in large performance spaces, the SB528zP-WP provides deep, powerful bass that enhances the listening experience.

The dual 18-inch cone drivers in the SB528zP-WP are designed for high power handling and efficient bass reproduction. These drivers are mounted in a vented enclosure that minimizes distortion and maximizes output, ensuring optimal performance even at high SPL levels. With a frequency range from 27 Hz to 147 Hz, the SB528zP-WP delivers an extended low-end response that fills large spaces with deep, rumbling bass. Its operating range is complemented by impressive SPL capabilities, with a calculated average SPL of 129 dB (whole space) and 135 dB (peak, whole space). In half-space, the subwoofer delivers a 135 dB (average) and 141 dB (peak) output, making it suitable for the most demanding environments that require substantial bass power.

Designed for flexibility in professional setups, the SB528zP-WP can be configured for either single-amp or dual-amp operation. It features a nominal impedance of 4 ohms for each driver, with a minimum impedance of 3.9 ohms at 131 Hz, ensuring compatibility with most professional amplifiers. The recommended high-pass filter is set at 25 Hz with a 12 dB/octave Butterworth slope, which helps protect the drivers while optimizing performance across the subwoofer's frequency range. The subwoofer's DSP with a 1-way filter further enhances the LF response, ensuring precise low-frequency reproduction.

The SB528zP-WP is built for durability, featuring an enclosure made from Baltic birch plywood, known for its strength and resonance control, which reduces unwanted vibrations and ensures consistent, high-quality performance over time. The subwoofer is finished with a wear-resistant textured black paint, making it resistant to damage and ensuring it maintains a professional appearance. The grille is made of powder-coated perforated steel, providing protection for the drivers while allowing sound to pass freely for optimal performance. The subwoofer is also rated IP56, ensuring it is protected against dust and water, which makes it suitable for both indoor and outdoor installations in environments where weather conditions might be a factor.

The subwoofer's compact dimensions of 30.19 x 50.69 x 24.56 inches and its weight of 215 lbs make it a substantial, yet manageable, solution for venues that require powerful bass in a reliable, high-performance package. Whether used in large auditoriums or outdoor installations, the SB528zP-WP is engineered to provide superior sound quality in any setting.
