Comparable 1.5" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Wavecor FR040WA02 1-1/2" Neodymium Aluminum Cone Full-Range 8 Ohm 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: 0.5 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 Wavecor FR040WA02 1-1/2" Neodymium Aluminum Cone Full-Range 8 Ohm?
A simple ported box is not recommended for Wavecor FR040WA02 1-1/2" Neodymium Aluminum Cone Full-Range 8 Ohm: the textbook alignment (1.5 liters tuned to 203.2 Hz) needs a 5.9 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 Wavecor FR040WA02 1-1/2" Neodymium Aluminum Cone Full-Range 8 Ohm be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 0.057 liters with a Qtc of 1.739 (above Butterworth: Qtc cannot fall below Qts (1.23)), the system exhibits an F3 of 291.8 Hz.
What port dimensions should be used for Wavecor FR040WA02 1-1/2" Neodymium Aluminum Cone Full-Range 8 Ohm to avoid port chuffing?
A straight 5.0 cm port would need 5.9 cm of length, which does not fit a practical cabinet. Use a passive radiator or a folded/3D duct instead of a straight tube.
