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. EBP 59 48 97 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. Model # Sealed Minimum (Cu. Ft.) Maximum (Cu. Ft.)
