Comparable 12.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Eminence SWAMP THANG-16 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: 0.8 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 Eminence SWAMP THANG-16?
Load Forge's calculated alignment puts Eminence SWAMP THANG-16 in a 21.1 liter vented enclosure tuned to 96.0 Hz, reaching an F3 cutoff of approximately 124.2 Hz.
Can Eminence SWAMP THANG-16 be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 26.4 liters with a Qtc of 0.877 (above Butterworth), the system exhibits an F3 of 130.0 Hz.
What port dimensions should be used for Eminence SWAMP THANG-16 to avoid port chuffing?
Sized from cone displacement (Sd × Xmax), a minimum port diameter of 10.0 cm with a length of 5.0 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.
