For high frequencies, WPL uses 3 × 1” exit neodymium compression drivers, each on its own horn with genuine 90° constant directivity.
This architecture — combined with the high 4kHz crossover enabled by the mid horn — provides:
- Significantly lower HF distortion than large-format compression driver designs
- Cleaner reproduction exactly where human hearing is most sensitive
- More open, extended top-end
- No “break-up region” harshness common in larger diaphragms
- Patented kite-shaped horn wedges that flatten the wavefront for true line-array summation
Put simply: highs stay pristine, controlled, and fatigue-free, even at high SPL levels.
