FEATURES
Featuring a compact form factor, the CBL528 makes an excellent choice for permanent installations such as fitness & sports venues, conference centers and Houses of Worship.
With its wide 180° horizontal and 45° vertical dispersion, this loudspeaker supports a frequency range from 54 Hz to 18 kHz—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.
- Highly focused pattern with consistent frequency response throughout the frequency range, on and off-axis.
- Symmetrical dispersion pattern.
- Four x 5" low-frequency drivers, with tightly designed acoustic centers, minimize comb-filtering with a frequency response down to 54 Hz.
- Eight x 2" mid-high frequency drivers.
- Patent pending mid-high frequency gain shading provides a smooth and controlled 45° vertical pattern from 420 Hz to 18 kHz.
- Bi-amped design for system integration with Blaze Audio Amplifiers.
- 180° symmetrical horizontal pattern control.
- Ultra low-distortion drivers
- System range 54 Hz - 18 kHz
