Frequently asked questions
Can I use the CBT 1000E without a CBT 1000 column speaker?
No. The CBT 1000E is a dedicated bass extension module designed to pair with the CBT 1000 via a coupler plate. It is not a standalone system.
Which is better for a small bar or club?
The AC599 is more appropriate for smaller venues. It is a complete system with 500W handling and 90-degree coverage, whereas the CBT 1000E is optimized for mid-to-large installations requiring high SPL output and extended bass.
What is the key performance difference?
The AC599 delivers balanced full-range sound with a 15-inch woofer and 1-inch compression driver. The CBT 1000E focuses solely on low-frequency extension (below 38 Hz) via six 6.5-inch drivers and requires a separate column speaker for midrange and high-frequency reproduction.
Which has higher power handling?
The CBT 1000E is rated for 1500W, compared to the AC599's 500W. However, power handling alone does not determine suitability—the AC599 is a complete system while the CBT 1000E is an extension module for larger setups.
