Frequently asked questions
Is the CBT 1000E a standalone speaker, or do I need something else?
The CBT 1000E is an extension module only and requires a CBT 1000 column speaker to function as a full-range system. It is not standalone.
How does the CBT 70J-1 compare in bass output and SPL to the combined CBT 1000 + 1000E system?
The CBT 70J-1 achieves 117 dB maximum peak SPL with a 500W continuous rating and 60 Hz–20 kHz frequency response. The CBT 1000E with its paired 1000 delivers 124–130 dB SPL in the midrange (65–300 Hz) and extends below 38 Hz, making the combined system substantially louder and deeper. The 1000E system is designed for larger venues and touring; the 70J-1 is for mid-sized venues and controlled coverage.
Which speaker is better for a church or retail space?
The CBT 70J-1 is purpose-built for houses of worship and retail with its J-shaped directional design, minimal spillover, articulate highs, and lightweight 21 lb construction. The CBT 1000E is an extension module designed for large-venue and touring scenarios and would not be suitable as a standalone solution.
Can I mount both systems to a wall?
Yes, the CBT 70J-1 includes integrated wall-mount hardware and fly points for easy rigging. The CBT 1000E pairs mechanically with the CBT 1000 via an included coupler plate and can be wall-mounted as part of that combined system, though its primary design is for floor or rigging-based deployment in large venues.
