Notes
Build notes
Sample data: values are illustrative, not measured.
15“ bass reflex sub using the 15SW115-8. Smaller and lighter than the 18“ equivalent. The SW series has higher Xmax than the DS, which matters at 38 Hz Fb.
Port
- Dual round ports, 100 mm diameter each
- Port length: 340 mm
- Tuning: 38 Hz (Fb)
Usage
Low-pass at 80-100 Hz. Pairs well with the 15“ mid horn for a compact two-way system.
