Two enclosure recommendations are listed for
each model, one sealed and one ported. The
sealed enclosure will, in most cases, give you the
best overall sound quality and take up the least
space in your vehicle.The ported enclosure design
will deliver additional output over the sealed
enclosure (about 3-4 dB more) and will also
maintain excellent sound quality, but it will require
significantly more space to install. The
recommended ported enclosure is not designed
for peaky “competition SPL” performance, it is
designed for music listening. It will be very loud
and sound extremely good when set up properly.
In addition to the enclosure recommendations,
we also provide recommended amplifier settings
for JL Audio amplifiers used with W7’s. Some of
this information is also applicable with other
brands of amplifiers (like crossover points and
slopes), some is not (like the voltage levels
specified for input sensitivity settings). You will
notice that our recommended settings do not
include any bass EQ boost... this is because W7’s
rarely require any equalization to produce smooth
frequency response. If you have an equalizer in
your system (or one is included in your head unit
or amplifier), defeat all bands below 125 Hz
before dialing in your new system settings. Please
turn off all sound processing that would affect the
subwoofers (loudness circuits for example).
