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.
