A port velocity of 20% or under is good for everday use and 5% or under for SPL competition . Port velocity
translates to port noise, so the lower the number, the less port noise you will incur.
An EBP of less then 45 is SUGGESTED for only a sealed box and greater then 65 for a ported box.

The larger a sealed box is, the lower the sub will play, but the less power it will handle. The smaller a sealed box is,
the higher the frequency the sub will play, and the more power it will handle.
