Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for RCF MR8N301?
A simple ported box is not recommended for RCF MR8N301: the textbook alignment (1.7 liters tuned to 318.6 Hz) needs a 12.4 cm port, and no nearby retune stays buildable without a bass hump. A sealed box, a passive radiator or a folded duct is the practical choice.
Can RCF MR8N301 be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 0.75 liters with a Qtc of 0.707 (Butterworth), the system exhibits an F3 of 546.1 Hz.
What port dimensions should be used for RCF MR8N301 to avoid port chuffing?
A straight 12.5 cm port would need 12.4 cm of length, which does not fit a practical cabinet. Use a passive radiator or a folded/3D duct instead of a straight tube.
