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

Bass Performer
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
y
ou will incur.
Ultimate SPL Bass Box (not designed for competition use)
