Powder coated steel grille with a high transmission ratio.
Three x 2” vertically arrayed HF drivers
Two x 5” custom LF drivers
CBL523 Passive, 2-way Constant
Beamwidth Loudspeaker
The ultra-compact and innovatively designed CBL523 is a perfect fit where on-wall distributed audio is needed. The 20.5 x 35cm (8″ x 14″) enclosure features two 5” low-frequency drivers complimented by a vertical constant directivity array of three 2” high-frequency drivers, delivering 119dB of maximum SPL in a focused 160° (horizontal) x 55°* (vertical) pattern.
The CBL523 has versatile mounting options with custom designed hardware, as well as the ability to stack and suspend two units together for increased SPL and an increased vertical pattern.

* Frequency response and range measured on-axis with recommended active EQ in an anechoic environment.
** Power handling tested using pink noise filtered to meet IEC 268-5, 6 dB crest factor, 100 hours, with recommended EQ.
*** Sensitivity measured in free field (no boundary-loading gain) with recommended active EQ, referenced to 1 W/1 m.
**** Maximum SPL calculated from sensitivity and power handling specifications, exclusive of power compression (100 Hz-10 KHz).
Results that exceed expectation. Control where it matters.
*R&D of this loudspeaker has been thoroughly measured and tested with a Klippel Analyzer System certified by Klippel GmbH.
Do I have to EQ the speakers?
No, download the EQ settings for the Blaze speakers from our website and upload them to a Blaze PowerZone Connect amplifier. The EQ settings also contain FIR filters, limiters, and crossovers for the CBL528.
Can I use all types of Speakon connectors and cables for the CBL523 and CBL528?
Yes and No! The CBL523 can be used with a 2 or 4-pole Speakon connector. The CBL528 uses a 4-pole Speakon connector as this speaker is bi-amped. Use cable thicknesses according to the lengths of the cable. (A schematic can be found on our website here)
How many CBL523 can I connect to one (1) PowerZone Connect 504?
The CBL523 is a 4-ohm speaker, and therefore, one speaker can be connected to each output. Meaning, 4 speakers in total on a PowerZone Connect 504 amplifier. For more speakers connected in parallel, use the larger 2U amplifiers as they can handle down to 2-ohm loads.
Is there a preferred amplifier for the CBL523 and CBL528?
In theory, all the PowerZone Connect amplifiers can be used. However, for the CBL523, the Connect 252/504 is a good match. To get full power, the bigger versions are recommended. For the CBL528, we recommend the Connect 3004, but lesser models can suffice if full power isn’t needed. Using the EQ settings from our website, the speakers are protected with limiters.
