Comparable 8.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Visaton 292-548 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
- Large enclosure volume (156.2 L) requires extensive internal matrix bracing to prevent panel resonance.
- Limited linear excursion (Xmax: 2.0 mm); set a high-pass subsonic filter at 25–30 Hz when driven with high power.
