Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for FaitalPRO 12PR310 (16Ω)?
Load Forge's calculated alignment puts FaitalPRO 12PR310 (16Ω) in a 52.1 liter vented enclosure tuned to 46.8 Hz, reaching an F3 cutoff of approximately 64.3 Hz.
Can FaitalPRO 12PR310 (16Ω) be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 65.1 liters with a Qtc of 0.948 (above Butterworth), the system exhibits an F3 of 63.9 Hz.
What port dimensions should be used for FaitalPRO 12PR310 (16Ω) to avoid port chuffing?
Sized from cone displacement (Sd × Xmax), a minimum port diameter of 10.0 cm with a length of 13.5 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.
