Notes
Build notes
Sample data: values are illustrative, not measured.
Classic scoop-style front-loaded horn around the 18SW115-8. The wide mouth and shallow fold give strong output from 40-120 Hz with a characteristic scooped voicing suited to reggae and dub systems.
Horn geometry
- Mouth area: ~5400 cm² (wide-mouth scoop)
- Throat matched to driver Sd (1210 cm²)
- Single-fold path; driver fires upward into the fold
- Expansion ratio: ~1.35
Usage
Horizontal stacking of scoops increases coupling and directivity at low frequencies. Typical crossover to mid horn at 100-120 Hz.
