Comparable 8.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Accuton C220-6-114E Ceramic 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
- The textbook alignment (5.9 L at 50.1 Hz) would need a 68.6 cm port; the recommendation is retuned to 5.9 L at 67.6 Hz so the port can be built.
