EAW QX594i-WP - 1000W 4 x 12-inch Passive 3-Way IP64-Rated Installation Loudspeaker with 90 x 45-Degree Coverage in Black Finish

The EAW QX594i-WP BLACK is a high-performance, 1000W passive 3-way installation loudspeaker designed to provide exceptional output, broadband pattern control, and exceptional fidelity for a wide range of permanent installation applications. With an IP64 rating, this speaker is built to withstand harsh environments, making it suitable for both indoor and outdoor installations where protection from dust and water is essential. Its high output level makes the QX594i-WP BLACK perfect for long-throw coverage in venues such as arenas and stadiums, as well as high-energy environments like live music venues and dance clubs. The broadband pattern control ensures that it performs well in acoustically challenging environments, such as cathedrals or highly reverberant public spaces, while its exceptional fidelity satisfies the most critical listeners in concert halls and performing arts centers.

At the core of the QX594i-WP BLACK lies an ultra-efficient mid/high compression driver, paired with a 90° (horizontal) x 45° (vertical) constant directivity horn. This ensures precise and broad sound dispersion, making it perfect for delivering even coverage across large areas. The QX594i-WP BLACK features four Phase Aligned 12-inch low-frequency transducers, arranged in vertical and horizontal pairs. This arrangement maximizes beneficial interactions between the drivers and extends pattern control into the low-frequency range. The low-frequency drivers surround the coaxial mid/high compression driver symmetrically in both the horizontal and vertical planes, ensuring that the sound across the entire frequency spectrum originates from a single point in space. This design eliminates typical phase anomalies that occur in systems with offset frequency sections, providing seamless coherence and clarity across the entire coverage area, both horizontally and vertically.

The QX594i-WP BLACK operates in a bi-amplified, three-way configuration, with dedicated drivers for low, mid, and high frequencies. It includes four 12-inch phase-aligned cone transducers for low frequencies, a 2-inch exit, 3.5-inch compression mid driver for midrange frequencies, and a 2-inch exit, 1.75-inch compression driver for high frequencies. The system's operating range spans from 55 Hz to 19 kHz, ensuring full-range sound reproduction with excellent clarity and depth. The nominal beamwidth of 90° horizontal and 45° vertical ensures even and precise coverage in large spaces. The calculated axial output limits of 136 dB (average) for low frequencies and 133 dB (average) for mid/high frequencies, combined with a maximum SPL of 145 dB, ensure that the QX594i-WP BLACK can handle demanding, high-energy applications while delivering powerful sound without distortion.

Constructed from exterior-grade Baltic Birch plywood and finished with a wear-resistant textured black paint, the QX594i-WP BLACK is built for durability and reliability in even the most demanding installations. The durable powder-coated perforated steel grille offers added protection for the internal components while allowing for optimal sound performance. With dimensions of 28 x 28 x 23.8 inches and a weight of 149 lbs, the QX594i-WP BLACK is designed to provide long-lasting performance in professional environments. A six-year warranty ensures the speaker's reliability and longevity, providing peace of mind for users requiring top-tier sound quality and robust build quality for demanding installations.
