EAW QX364 White 2-Way Trapezoidal Enclosure Loudspeaker (White)

Compact Two-Way Loudspeaker for Demanding Installations
The EAW QX364 WHITE is a high-output 1800W passive 2-way loudspeaker engineered for professional sound reinforcement in acoustically complex environments. It brings the power and clarity of the QX500 Series to a smaller, more installation-friendly format. Designed with a large 4-inch voice coil compression driver, this system delivers clean, coherent sound that reaches mid to large audience areas with precision. Perfect for stadiums, arenas, performance halls, and reverberant public venues, the QX364 WHITE ensures high intelligibility and tight pattern control in any application.

Symmetrical Driver Layout Enhances Coherent Sound
At the core of the QX364 WHITE’s performance is a carefully engineered driver configuration. Four 10-inch low-frequency transducers are arranged in vertical and horizontal Phase Aligned™ pairs surrounding the central high-frequency driver. This symmetrical layout ensures that the entire frequency response behaves as though it’s originating from a single source, eliminating phase inconsistencies that degrade clarity. This approach provides the precision necessary to maintain consistency across both horizontal and vertical coverage areas.

Controlled Coverage with Replaceable Horn Options
The QX364 WHITE features a 60° x 45° constant directivity horn, offering tight, predictable coverage with minimal off-axis coloration. It's one of six beamwidth options available, letting system designers tailor dispersion to the venue’s specific acoustics. From concert halls to complex architectural spaces, this horn’s broadband pattern control enables accurate placement of sound while minimizing reflections. Its design is ideal for achieving intelligibility in difficult rooms without requiring excessive EQ or energy.

Flexible Amplification and System Integration Options
With selectable single-amp or bi-amp modes, the QX364 WHITE accommodates a variety of amplification strategies. Each woofer pair can be independently wired for series or parallel operation, allowing integrators to fine-tune their systems for impedance matching or system design constraints. A built-in high-pass filter at 70 Hz (12 dB/octave Butterworth) simplifies integration with subwoofers or larger system arrays, keeping the low-end clean while extending the midrange presence.

Built for Rigorous Installations Indoors or Outdoors
The QX364 WHITE is housed in a rugged Baltic birch plywood cabinet and finished with textured white paint for an understated look that fits any architectural setting. A perforated powder-coated steel grille protects internal components without obstructing acoustic performance. The enclosure is built to withstand years of use in high-demand venues, and with an IP64 rating, it is also available in weather-protected versions for outdoor or humid installations.

Power and Performance Without Compromise
The QX364 WHITE is capable of delivering up to 144 dB peak SPL and maintains a calculated average output of 138 dB. With an operating range from 66 Hz to 20 kHz and 109 dB axial sensitivity, it offers headroom for dynamic content and the sonic finesse required for music or spoken word. Whether used as a main speaker in a full-range system or as part of a broader distributed array, it delivers consistent fidelity and punch from venue to venue.
