Comparable 8.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the ETON 12-610/25 HEX Woofer 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 (7.4 L at 53.6 Hz) would need a 56.9 cm port; the recommendation is retuned to 7.4 L at 80.4 Hz so the port can be built.
