Comparable 8.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Dayton Audio Reference RS100P-8 Full-range 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 (2.7 L at 69.9 Hz) would need a 77.7 cm port; the recommendation is retuned to 2.7 L at 90.9 Hz so the port can be built.
- Limited linear excursion (Xmax: 3.7 mm); set a high-pass subsonic filter at 25–30 Hz when driven with high power.
