⚠️ Engineering Notice for Builders
- The textbook alignment (44.0 L at 30.2 Hz) would need a 220.4 cm port; the recommendation is retuned to 88.0 L at 31.7 Hz so the port can be built.
- Port length (92.2 cm) exceeds a straight internal run; use an elbow bend, slotted vent or 3D folded duct to fit the enclosure.
