Balanced sound field is ensured across the frequency range and declared coverage angle even in the most demanding listening environments, such as churches or public spaces known for numerous reflections. Exceptional fidelity of reproduction will satisfy even the most discerning listeners in concert halls and theaters. These 3-way loudspeakers feature a trapezoidal enclosure and utilize a unique ultra-powerful compression driver. In the model designation of QX5xx series with coverage angles of 45x45°, 60x45°, 60x60°, and 90x60°, the 2nd digit indicates the horizontal and the 3rd digit the vertical angle. Four 12" low-frequency drivers are symmetrically arranged around coaxially aligned 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.
