Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Tang Band W1-2025SA 1" Neodymium Full Range Driver?
A simple ported box is not recommended for Tang Band W1-2025SA 1" Neodymium Full Range Driver: the textbook alignment (1.5 liters tuned to 169.0 Hz) needs a 10.2 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 W1-2025SA 1" Neodymium Full Range Driver be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 0.05 liters with a Qtc of 0.672 (below Butterworth), the system exhibits an F3 of 288.0 Hz.
What port dimensions should be used for Tang Band W1-2025SA 1" Neodymium Full Range Driver to avoid port chuffing?
A straight 5.0 cm port would need 10.2 cm of length, which does not fit a practical cabinet. Use a passive radiator or a folded/3D duct instead of a straight tube.
