[Shotimes] subwoofer replacement

[Bill Murray]

If the JBL box is indeed .33 ft3, the 6w0 is too small.  According to
JLs site, the 6w0 works best in a sealed enclosure between .15-.22 ft3.
I would side more towards the smaller side to get the tightest and most
accurate sound possible.  The 8w0 on the other hand requires .3-.6 ft3,
so the JBL box would be about perfect for the 8w0.  So I'd still go with
an 8", plus an 8" is much more available from other manufactures, then a
6" is.  And the 8" will be louder, if thats what you're looking for by
upgrading.

Bill:
 I think your right on the signal level. Also that small of a driver
needs
to be pushed harder to get as low as possible. The box volume is
acutally
almost perfect for the JL Audio speaker. We have somewhere around .33
ft3 in
the box and that's within the recomened range for the subwoofer. The 8"
models usually are looking for more volume. I thought about a free air
setup
but nobody I talked to had any good comments. I also could not find
anybody
with decent sound running one.
