Comparable 16.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Supravox 380-2000 EXC LC Haut-parleur de grave / 8 Ohms does not fit your target box volume or tuning. Each entry links to its full enclosure design and Thiele/Small parameters.
⚠️ Engineering Notice for Builders
- The textbook alignment (205.9 L at 34.3 Hz) would need a 50.6 cm port; the recommendation is retuned to 205.9 L at 36.0 Hz so the port can be built.
- Xmax is not published, so the port size is an empirical estimate (area ≥ 12 in² per ft³ of net volume, minimum by driver size), not a displacement calculation. Check air velocity in Load Forge Studio.
- Large enclosure volume (205.9 L) requires extensive internal matrix bracing to prevent panel resonance.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Supravox 380-2000 EXC LC Haut-parleur de grave / 8 Ohms?
Load Forge's calculated alignment puts Supravox 380-2000 EXC LC Haut-parleur de grave / 8 Ohms in a 205.9 liter vented enclosure tuned to 36.0 Hz, reaching an F3 cutoff of approximately 36.2 Hz.
Can Supravox 380-2000 EXC LC Haut-parleur de grave / 8 Ohms be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 91.3 liters with a Qtc of 0.707 (Butterworth), the system exhibits an F3 of 71.8 Hz.
What port dimensions should be used for Supravox 380-2000 EXC LC Haut-parleur de grave / 8 Ohms to avoid port chuffing?
Xmax is not published for Supravox 380-2000 EXC LC Haut-parleur de grave / 8 Ohms, so the port is an empirical estimate: a 26.8 cm diameter with a length of 44.2 cm (area at least 12 in² per ft³ of net volume). Check the air velocity at your power level in Load Forge Studio.
