Frequently asked questions
Can these two work together?
Yes. The 321C covers mid-to-high frequencies (1.8 kHz and up via its compression driver), while the 50S/T-WH handles 50–150 Hz bass. Use the 321C as a satellite with the 50S/T-WH subwoofer for extended low-end in larger installations.
Which is better for speech reinforcement?
The Control 321C. Its 47 Hz–16 kHz response, 94 dB sensitivity, and controlled 90° dispersion are optimized for clear speech coverage in institutional environments. The 50S/T-WH is bass-only (50–150 Hz) and cannot reproduce speech intelligibility on its own.
What's the main installation difference?
The 321C is recessed into standard ceiling grids (366 × 366 mm footprint, 223 mm depth). The 50S/T-WH surface-mounts on walls or ceilings without cavity work, making it faster for retrofits but more visible.
Which handles higher volume?
The 321C reaches 118 dB SPL (1 m), while the 50S/T-WH peaks at 121 dB. However, the 321C is designed for full-range coverage; the subwoofer only reproduces bass frequencies and is meant to pair with satellites for balanced output.
