These speakers provide a balanced sound field throughout the frequency range and the declared dispersion angle, even in challenging listening environments like churches or public spaces known for multiple reflections. Exceptional fidelity in sound reproduction will satisfy even the most demanding listeners in concert halls and theaters. The 3-way speakers feature a trapezoidal enclosure and utilize a unique ultra-powerful compression driver. The model numbers in the QX5xx series with dispersion angles of 45x45°, 60x45°, 60x60°, and 90x60° indicate the horizontal and vertical angles respectively. Four 12" low-frequency drivers are symmetrically positioned around coaxially arranged 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.
