Comparable 6.5" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Dayton Audio 295-104--epique-e180he-44 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 (24.2 L at 29.6 Hz) would need a 46.5 cm port; the recommendation is retuned to 24.2 L at 31.1 Hz so the port can be built.
