Comparable 10.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the GAS Audio Power MAD S3-10D2 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 (19.9 L at 34.9 Hz) would need a 142.8 cm port; the recommendation is retuned to 25.9 L at 36.6 Hz so the port can be built.
- Port length (97.1 cm) exceeds a straight internal run; use an elbow bend, slotted vent or 3D folded duct to fit the enclosure.
