Comparable 16.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the TAD TL-1601b 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
- Large enclosure volume (208.2 L) requires extensive internal matrix bracing to prevent panel resonance.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for TAD TL-1601b?
Load Forge's calculated alignment puts TAD TL-1601b in a 208.2 liter vented enclosure tuned to 31.1 Hz, reaching an F3 cutoff of approximately 30.8 Hz.
Can TAD TL-1601b be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 92.4 liters with a Qtc of 0.707 (Butterworth), the system exhibits an F3 of 57.2 Hz.
What port dimensions should be used for TAD TL-1601b to avoid port chuffing?
Sized from cone displacement (Sd × Xmax), a minimum port diameter of 12.5 cm with a length of 9.3 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.
