Frequently asked questions
Can I use the CBT 70JE-1 as a standalone speaker?
No. The CBT 70JE-1 is an extension module designed only to work when stacked with a CBT 70J-1 base unit. The CBT 50LA-LS-WH, by contrast, is a complete standalone column speaker.
Which speaker is better for outdoor use?
The CBT 50LA-LS-WH carries an IP-55 weather-resistant rating and UV-resistant paint, making it purpose-built for outdoor and wet environments. The CBT 70JE-1 extension is designed for professional indoor venues and does not feature equivalent weatherproofing.
What is the main acoustic difference between these two?
The CBT 50LA-LS-WH prioritizes clean, speech-optimized output (80 Hz–20 kHz) with switchable speech/music modes, while the CBT 70JE-1 extension adds extended bass to 45 Hz and provides switchable vertical coverage modes (Narrow 25° or Broad 45°) for more sophisticated pattern control. The extension suits venues needing deeper bass and tighter directivity.
What is the skill level required for each?
The CBT 50LA-LS-WH supports beginner through professional installers with its straightforward design and included wall bracket. The CBT 70JE-1 extension is rated for professional use only and requires integration with an existing CBT 70J-1 base unit.
