Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for BMS 6CN160?
Load Forge's calculated alignment puts BMS 6CN160 in a 6.0 liter vented enclosure tuned to 87.6 Hz, reaching an F3 cutoff of approximately 88.1 Hz.
Can BMS 6CN160 be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 2.7 liters with a Qtc of 0.707 (Butterworth), the system exhibits an F3 of 157.3 Hz.
What port dimensions should be used for BMS 6CN160 to avoid port chuffing?
Sized from cone displacement (Sd × Xmax), a minimum port diameter of 6.8 cm with a length of 18.8 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.
