Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Tang Band W2-2040S?
A simple ported box is not recommended for Tang Band W2-2040S: the textbook alignment (1.5 liters tuned to 105.9 Hz) needs a 31.4 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 Tang Band W2-2040S be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 0.05 liters with a Qtc of 0.57 (below Butterworth), the system exhibits an F3 of 169.0 Hz.
What port dimensions should be used for Tang Band W2-2040S to avoid port chuffing?
A straight 5.0 cm port would need 31.4 cm of length, which does not fit a practical cabinet. Use a passive radiator or a folded/3D duct instead of a straight tube.
