EAW – QX544i • 3-way passive full-range speaker • bi-amp • LF 2000/4000 W / 2 ohm (2x1000/2000 W / 4 ohm), MF/HF 175/350 W / 8 ohm • LF 4 x 12" + MF 1 x 2" exit with 3.5" diaphragm + HF 1 x 2" exit 1.75" coil • frequency range -10 dB: 55 - 20000 Hz • max SPL: 142 dB • trapezoidal enclosure • dispersion angle: 90 x 60° • 710 x 710 x 605 x 403 (mm) • 61 kg The new series of speakers, EAW QX500, with their powerful performance, are suitable for sound reinforcement over long distances in arenas, stadiums, live concerts, or dance clubs where high volume is required. Balanced sound coverage is ensured across the frequency range and declared dispersion angle even in the most challenging listening environments, such as churches or public spaces known for high reverberation. The exceptional fidelity of reproduction will satisfy even the most discerning listeners in concert halls and theaters. The 3-way speakers feature a trapezoidal enclosure and utilize a unique ultra-powerful compression driver. In the model designation of QX5xx series with dispersion angles of 45x45°, 60x45°, 60x60°, and 90x60°, the second digit indicates the horizontal and the third digit the vertical angle. Four 12" low-frequency drivers are symmetrically arranged around coaxially positioned HF & MF drivers, simulating a single point source for the entire frequency spectrum. This ideal sound coherence is maintained across both horizontal and vertical angles.
