Frequently asked questions
Which speaker is better for touring bands?
The PRX915 is purpose-built for touring and mobile events. It is self-powered, portable, and includes onboard processing (EQ, feedback suppression) and app control. The CBT 100LA-LS is fixed-installation hardware designed for permanent venues and distributed audio networks.
Which speaker works for emergency or life-safety systems?
Only the CBT 100LA-LS carries EN54-24 certification, which is required for emergency broadcast and life-safety applications. The PRX915 is a general-purpose powered speaker with no safety-system certification.
What is the key output and power difference?
The PRX915 delivers 133 dB max SPL with 2000W peak power and is fully amplified onboard. The CBT 100LA-LS is passive, with 92 dB @ 4 meters EN54-certified SPL and requires external amplifier and 70V/100V distributed wiring. The PRX915 is designed for higher-energy live sound; the CBT is for speech clarity in larger distributed systems.
Which is easier to set up for a one-off event?
The PRX915 arrives ready to plug in and play—no amplifier, wiring, or external gear required. The CBT 100LA-LS requires permanent or semi-permanent installation with distributed 70V/100V wiring and an external amplifier, making it better suited to venues rather than mobile events.
