⚠️ Engineering Notice for Builders
- The textbook alignment (12.3 L at 26.6 Hz) would need a 120.2 cm port; the recommendation is retuned to 12.3 L at 29.3 Hz so the port can be built.
- Xmax is not published, so the port size is an empirical estimate (area ≥ 12 in² per ft³ of net volume, minimum by driver size), not a displacement calculation. Check air velocity in Load Forge Studio.
- Port length (98.2 cm) exceeds a straight internal run; use an elbow bend, slotted vent or 3D folded duct to fit the enclosure.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Edge EDS15D2-E0?
Load Forge's calculated alignment puts Edge EDS15D2-E0 in a 12.3 liter vented enclosure tuned to 29.3 Hz, reaching an F3 cutoff of approximately 29.6 Hz.
Can Edge EDS15D2-E0 be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 10.8 liters with a Qtc of 0.707 (Butterworth), the system exhibits an F3 of 48.5 Hz.
What port dimensions should be used for Edge EDS15D2-E0 to avoid port chuffing?
Xmax is not published for Edge EDS15D2-E0, so the port is an empirical estimate: a 6.8 cm diameter with a length of 98.2 cm (area at least 12 in² per ft³ of net volume). Check the air velocity at your power level in Load Forge Studio.
