Comparable 16.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Supravox 380-2000 LC low frequency driver / 96dB / 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
- Large enclosure volume (444.4 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 LC low frequency driver / 96dB / 8 Ohms?
Load Forge's calculated alignment puts Supravox 380-2000 LC low frequency driver / 96dB / 8 Ohms in a 444.4 liter vented enclosure tuned to 27.2 Hz, reaching an F3 cutoff of approximately 25.8 Hz.
Can Supravox 380-2000 LC low frequency driver / 96dB / 8 Ohms be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 193.3 liters with a Qtc of 0.707 (Butterworth), the system exhibits an F3 of 48.1 Hz.
What port dimensions should be used for Supravox 380-2000 LC low frequency driver / 96dB / 8 Ohms to avoid port chuffing?
Sized from cone displacement (Sd × Xmax), a minimum port diameter of 12.5 cm with a length of 2.3 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.
