Frequently asked questions
What's the difference between these two listings?
They are the same product. Both list the JBL Control 447HC with identical core specs: 6.5" coaxial design, 93 dB sensitivity, 119.5 dB peak SPL, 85° coverage, and 70V/100V transformer options. Minor descriptive emphasis differs, but performance and features are functionally identical.
Is this speaker suitable for live sound reinforcement?
Yes. The Control 447HC is listed as suitable for live sound reinforcement, conference spaces, and retail venues. Its 119.5 dB peak SPL and consistent coverage make it capable in these applications, though it is purpose-built for commercial ceiling installations rather than portable live sound systems.
What's the frequency response range?
The rated frequency range is 55 Hz to 20 kHz at -10 dB, delivering consistent coverage across the vocal and midrange frequencies essential for speech intelligibility and background music in commercial spaces.
How does the constant-voltage transformer system work?
The speaker includes built-in transformer taps for both 70V and 100V distributed systems at 60W, 30W, 15W, and 7.5W power levels. This eliminates the need for external transformers and allows multiple speakers to be daisy-chained on a single amplifier line while maintaining individual volume control.
