CBL528

Remarkably Adaptable

Ultra Flexible

• Constructed to thrive in various applications, from portable PA to fixed installations and beyond.
• Highly focused, uniform coverage
• Exceptionally precise directional characteristics, ensuring consistent frequency response across the entire range, regardless of the listening angle.
• DSP Ready
• Professionally tuned for PowerZone™ digital processing & amplification.

Super wide, tightly controlled

A crossover point at 420Hz continuing all the way up to 20KHz allows for a smooth blend of full range audio from the entire reflective physical space, rendering speech intelligibility holes obsolete.
180° HORIZONTAL COVERAGE

Fixed vertical coverage at 45° per unit, optimizing system configuration, shortening project deployment time, and improving the installation experience.

CBL528-BA Constant Beamwidth Loudspeaker with 180° of Horizontal Coverage with Integrated Gain-shading providing a 45° Vertical Pattern.

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.

• 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 shadingprovides a smooth and controlled 45º vertical pattern from 420Hz to 18kHz.
• Bi-Amped design for system integration withBlaze Amplifiers.
• 180º symmetrical horizontal pattern control.
• Ultra low-distortion drivers
• System range 54Hz - 18kHz
