EAW QX366-WP 2-Way Installation Loudspeaker (White)

High-output loudspeaker for mid-throw installations
The EAW QX366-WP WHITE is a weather-protected 2-way passive loudspeaker designed for permanent installation in large venues. Delivering 1800 watts of power and broadband pattern control, this compact solution from the QX300 Series replicates the performance of larger QX500 three-way systems in a smaller footprint. Its symmetrical driver layout and directivity pattern ensure clean sound delivery for medium-throw coverage in stadiums, arenas, and high-energy music venues.

Coaxial compression driver and constant directivity horn
At the core of the QX366-WP WHITE is a high-performance 4-inch voice coil HF compression driver, matched with a 60° x 60° horn for predictable coverage. The horn design is one of six available options, offering installation flexibility based on room acoustics. The horn and driver configuration ensure intelligibility, tight dispersion, and powerful output across the mid and high frequencies.

Symmetrical low-frequency driver layout for seamless coherence
To extend pattern control into the low frequencies, four Phase Aligned 10-inch LF transducers are arranged in vertical and horizontal pairs around the HF section. This symmetrical layout focuses the acoustic output, eliminating phase offset and making the entire frequency response appear as if it originates from a single source. The result is highly intelligible, coherent coverage across the entire listening area.

Flexible wiring and bi-amp/single-amp options
Installers can configure the QX366-WP for either single-amp or bi-amp operation. Each LF driver pair is brought out independently to the input panel, enabling custom wiring setups in series or parallel. The system includes a built-in 70 Hz high-pass filter (12 dB/oct Butterworth), improving integration with subwoofers and protecting LF drivers from over-excursion.

Durable enclosure for all-weather installations
Constructed from rugged Baltic birch plywood and coated with wear-resistant white paint, the QX366-WP WHITE is IP64 rated for dust and water resistance. A perforated steel grille protects internal components, making the loudspeaker well-suited for outdoor stadiums and sports facilities, as well as architectural spaces requiring weather-protected yet high-performance sound reinforcement.

Powerful SPL output with studio-grade fidelity
With a 66 Hz to 20 kHz operating range, the QX366-WP WHITE delivers full-range sound with clarity and impact. It reaches a maximum SPL of 143 dB (peak) and 137 dB (average), offering exceptional output for speech, music, and multimedia. Axial sensitivity is rated at 109 dB (LF/HF), ensuring high efficiency across operating conditions.
