Notes
Build notes
Sample data: values are illustrative, not measured.
Two 12NBX100-8 drivers in a shared bass reflex enclosure, wired in parallel to present 4 Ω. The dual-12 format gives a larger Sd than a single 15“ with a more compact footprint per driver.
Port
- Two round ports, 100 mm diameter each
- Port length: 310 mm
- Tuning: 44 Hz (Fb)
Wiring
Both drivers in parallel: nominal 4 Ω load. Ensure the amplifier is 4 Ω rated. Drivers should be matched (same production batch if possible) to keep displacement symmetrical.
