ecifications
Remember to build
our box to the total volume, not
ust air space, as total volume includes all displacement.
An EBP of less then 45 is SUGGESTED for onl
a sealed box and
reater 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 hi
her the frequenc
the sub will pla
, and the more power it will handle.
All ports listed are circle ports unless otherwise stated. Surface area of a circle port =

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
ou will incur.
