EAW ( QX544i BLACK / QX544i-WP BLACK [weather-proof] ) Passive Live Sound Speaker

The QX544i BLACK / QX544i-WP BLACK is a part of the new QX Series that is capable of delivering the high output, broadband pattern control and exceptional fidelity designed for a wide range of permanently installed applications. Its high output level are making it appropriate designed for long throws in arenas and stadiums or for high-energy applications like live music venues or dance clubs. Its broadband pattern control is intended for letting it to tame hostile acoustical environments like cathedrals or highly reverberant public spaces. And its exceptional fidelity pleases the most critical listeners in concert halls and performing arts centers.

The QX544i comes loading an ultra-efficient mid/high compression driver that comes along with a 45° (h) x 45° (v) constant directivity horn. Four Phase Aligned™ 12-in low frequency transducers arranged as vertical and horizontal pairs leverage beneficial interaction based on their spacing for extending the pattern control well into the low frequency range.

Because the four low frequency transducers surround the coaxial mid/high compression driver symmetrically in both the horizontal and vertical planes, response across the full frequency spectrum appears to originate from a single point in space. This basic design comes facilitating an idealized summation of the three frequency sections, this eliminates the anomalies associated along with designs that physically offset the sections. This idealized coherence applies in both the horizontal and vertical planes throughout the coverage area.

Note: The QX544i-WP BLACK is a weather-proof version.
