Suggested box alignments:
- Sealed box of 0.2 to 0.25 cubic feet (5.5 liters to 7 liters) should have a response of 3dB down on the low end of about 80Hz.
- A ported enclosure of 0.35 cubic feet (10 liters) with a 1.5" diameter vent by 4" long should have a 3dB down point of about 55Hz.
- A ported enclosure of 0.5 cubic feet (14 liters) with a 2" diameter vent by 7" long should have a 3dB down point of about 48Hz.
