Comparable 8.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the LaVoce LAVMAF08200AF 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 (1.5 L at 147.4 Hz) would need a 28.5 cm port; the recommendation is retuned to 3.0 L at 103.2 Hz so the port can be built.
- Limited linear excursion (Xmax: 2.6 mm); set a high-pass subsonic filter at 25–30 Hz when driven with high power.
