optimal crossover setting
We recommend using an active crossover with a 12 to 18dB per octave low
pass lter slope, and setting it to an initial setting of 80 to 90Hz as a good
starting point. This is an optimal crossover setting on most vehicles.
inverting phase
Depending on the placement of your subwoofer enclosure and associated
components, it may be necessary to invert the phase of one or another of your
system’s connections in order to gain better subwoofer/mid-range blending.
Inverting the phase simply means switching the positive connections with the
negative connections at the amplier. If you choose to do this, invert the phase
of only one set of speakers (either your mains, or your subs, never both).
low frequency cut-off for mid-range
speakers in systems with subwoofers
Now that you have a subwoofer in your system, you may want to decrease
the amount of bass going to your midrange speakers. This will get you better
mid-range sound and increase the power handling. There are two ways to roll
off the bass before it gets to your mid-range speakers. One way is to use
a “bass blocker,” a capacitor placed in series with the speaker input. Bass
blockers are installed in series, one end connected with the positive lead from
your amplier and the other end connected to the positive lead of each of your
speakers. Bass blocker capacitors (200 microfarad @ 100V, non-polarized) are
available at any Radio Shack or electronic parts supply house. The other route
is to use an electronic crossover device that allows ltering below 100Hz or so.
Find these devices at your authorized Polk dealer.
