Comparable 5.25" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Wavecor WF132TU02 5-1/4" Paper Cone Mid-Woofer 4 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
- Xmax is not published, so the port size is an empirical estimate (area ≥ 12 in² per ft³ of net volume, minimum by driver size), not a displacement calculation. Check air velocity in Load Forge Studio.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Wavecor WF132TU02 5-1/4" Paper Cone Mid-Woofer 4 Ohm?
Load Forge's calculated alignment puts Wavecor WF132TU02 5-1/4" Paper Cone Mid-Woofer 4 Ohm in a 12.9 liter vented enclosure tuned to 54.5 Hz, reaching an F3 cutoff of approximately 49.7 Hz.
Can Wavecor WF132TU02 5-1/4" Paper Cone Mid-Woofer 4 Ohm be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 5.7 liters with a Qtc of 0.707 (Butterworth), the system exhibits an F3 of 98.2 Hz.
What port dimensions should be used for Wavecor WF132TU02 5-1/4" Paper Cone Mid-Woofer 4 Ohm to avoid port chuffing?
Xmax is not published for Wavecor WF132TU02 5-1/4" Paper Cone Mid-Woofer 4 Ohm, so the port is an empirical estimate: a 6.8 cm diameter with a length of 23.5 cm (area at least 12 in² per ft³ of net volume). Check the air velocity at your power level in Load Forge Studio.
