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

The EAW QX594i WHITE is a high-performance, 1000W passive 3-way installation loudspeaker, designed to deliver exceptional output, broadband pattern control, and outstanding fidelity for a wide range of permanent installation applications. With its high output level, the QX594i WHITE is perfect for long-throw applications in venues such as arenas and stadiums, as well as for high-energy environments like live music venues and dance clubs. The broadband pattern control ensures that the speaker performs exceptionally well in acoustically challenging environments such as cathedrals and highly reverberant public spaces, while its exceptional fidelity satisfies the most discerning listeners in concert halls and performing arts centers.

The QX594i WHITE features an ultra-efficient mid/high compression driver with a 90° (horizontal) x 45° (vertical) constant directivity horn. This combination ensures that the speaker delivers precise sound dispersion with broad and consistent coverage, making it ideal for large venues. The four Phase Aligned 12-inch low-frequency transducers are arranged in vertical and horizontal pairs, optimizing the interaction between the drivers to extend pattern control deep into the low-frequency range. The low-frequency drivers are symmetrically arranged around the coaxial mid/high compression driver, ensuring that the response across the full frequency spectrum appears to come from a single point in space. This eliminates phase anomalies that typically occur in designs where frequency sections are offset, resulting in a cohesive and seamless sound field throughout the coverage area, both horizontally and vertically.

The QX594i WHITE operates in a bi-amplified, three-way configuration, with dedicated drivers for low, mid, and high frequencies. The system 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 the high frequencies. With an operating range from 55 Hz to 19 kHz, the QX594i WHITE delivers full-range sound reproduction with clarity and depth. The nominal beamwidth of 90° horizontal and 45° vertical ensures wide and even coverage, making the speaker suitable for large venues that require consistent sound distribution. The QX594i WHITE has calculated axial output limits of 136 dB (average) for low frequencies and 133 dB (average) for mid/high frequencies, providing ample headroom for high-energy applications. It also boasts a maximum SPL of 145 dB, making it capable of producing powerful sound at high volumes.

Constructed from exterior-grade Baltic Birch plywood and finished with wear-resistant textured white paint, the QX594i WHITE combines durability and aesthetic appeal for installations that demand both performance and visual integration. The powder-coated perforated steel grille offers additional protection for the internal components while allowing for optimal sound output. With dimensions of 28 x 28 x 23.8 inches and a weight of 149 lbs, the QX594i WHITE is built for reliability in demanding professional environments. A six-year warranty ensures long-term performance, making it a dependable choice for any installation requiring high-quality sound and durability.
