The Blaze Audio CBL528 is a compact bi-amped constant-beamwidth loudspeaker designed for permanent installations where consistent coverage and intelligibility matter across the entire listening area. The cabinet supports a frequency range of 54 Hz to 18 kHz, with a symmetrical 180-degree horizontal by 45-degree vertical dispersion that keeps music natural and speech articulate whether listeners are directly in front, off to one side, or moving through the space.

Bi-amped operation separates low-frequency (320W AES @ 5.2Ω) and high-frequency (200W AES @ 8Ω) sections for the cleanest possible transient response and the highest available headroom from a cabinet this size. The white finish suits typical commercial interiors, while the controlled directivity makes the CBL528 well suited to fitness and sports venues, conference centers, multipurpose rooms, and houses of worship where listener positions move and shift during a session.

Bi-amped operation requires an amplifier with at least two output channels per cabinet — one for LF, one for HF — or a single Lo-Z amplifier configured to drive each section separately. Pair the CBL528 with PowerZone or PowerZone Connect amplifiers in the same project for matched system tuning and warranty alignment.
