2 JL AUDIO 15W3v2
*Xmax specifications are
derived via one-way voice
coil overhang method with
no correction factors
applied.
**Efficiency (1W/1m) is not
an accurate indicator of a
subwoofer’s output
capability and should not be
used as a comparison to
other subwoofers to
determine which one is
“louder”.
***Re (DC resistance) is
measured with the voice
coils in series, for parallel-
wired specification divide Re
by 4. All other
specifications remain the
same.
