Balanced sound coverage is ensured across the frequency range and declared coverage angle even in challenging listening environments like churches or public spaces prone to reflections. Exceptional sound fidelity will satisfy even the most discerning listeners in concert halls and theaters. These 3-way speakers feature a trapezoidal enclosure and utilize a unique ultra-powerful compression driver. The model numbers in the QX5xx series with coverage angles of 45x45°, 60x45°, 60x60°, and 90x60° indicate the horizontal and vertical angles respectively. 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.
