Overview

Featuring a compact form factor that minimizes both transportation and line-of-sight considerations, the CBL528 is ideally suited for use as a portable PA solution. And with its Bi-Amped design for system integration with Blaze amplifiers, it also makes an excellent choice for permanent installations such as performing arts venues, commercial theaters, and Houses of Worship.

With its wide 180-degree horizontal and 45-degree vertical dispersion, this loudspeaker supports a frequency range from 54Hz to 18kHz-ensuring clear, natural sounding music and highly articulate speech reproduction. Equally important, the CBL528’s symmetrical dispersion pattern ensures listeners hear consistent sound regardless of whether they are positioned in front of, to the left, or to the right of the loudspeaker.

Features

• Highly focused pattern with consistent frequency response throughout the frequency range, on and off-axis.
• Symmetrical dispersion pattern.
• Four 5” low-frequency drivers, with tightly designed acoustic centers, minimize comb-filtering with a frequency response down to 54Hz.
• Eight vertically mounted 2” mid-high frequency drivers.
• Patent pending mid-high frequency gain shading provides a smooth and controlled 45º vertical pattern from 420Hz to 18kHz.
• Bi-Amped design for system integration with Blaze Amplifiers.
• 180º symmetrical horizontal pattern control.
• Ultra-low-distortion drivers
• System range 54Hz – 18kHz
