Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for FaitalPRO 8FE300 (16Ω)?
Load Forge's calculated alignment puts FaitalPRO 8FE300 (16Ω) in a 11.5 liter vented enclosure tuned to 59.5 Hz, reaching an F3 cutoff of approximately 83.3 Hz.
Can FaitalPRO 8FE300 (16Ω) be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 14.4 liters with a Qtc of 0.933 (above Butterworth), the system exhibits an F3 of 83.5 Hz.
What port dimensions should be used for FaitalPRO 8FE300 (16Ω) to avoid port chuffing?
Sized from cone displacement (Sd × Xmax), a minimum port diameter of 6.8 cm with a length of 21.9 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.
