Comparable 10.2" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the SEAS XM006-04 L26RO4Y2 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 (14.0 L at 35.5 Hz) would need a 126.3 cm port; the recommendation is retuned to 14.0 L at 40.8 Hz so the port can be built.
- Port length (93.9 cm) exceeds a straight internal run; use an elbow bend, slotted vent or 3D folded duct to fit the enclosure.
