Comparable 2.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Tang Band W2-2136S does not fit your target box volume or tuning. Each entry links to its full enclosure design and Thiele/Small parameters.
⚠️ Engineering Notice for Builders
- Limited linear excursion (Xmax: 2.0 mm); set a high-pass subsonic filter at 25–30 Hz when driven with high power.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Tang Band W2-2136S?
A simple ported box is not recommended for Tang Band W2-2136S: the textbook alignment (1.5 liters tuned to 144.6 Hz) needs a 15.2 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 W2-2136S be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 0.062 liters with a Qtc of 0.707 (Butterworth), the system exhibits an F3 of 269.6 Hz.
What port dimensions should be used for Tang Band W2-2136S to avoid port chuffing?
A straight 5.0 cm port would need 15.2 cm of length, which does not fit a practical cabinet. Use a passive radiator or a folded/3D duct instead of a straight tube.
