LOW Frequency CUT-OFF for Systems with Subwoofers

GXR4 SPECIAL INSTRUCTIONS FOR IMPORT APPLICATIONS (TOYOTA/MITSUBISHI)

GXR4 models have flanges that can be removed to facilitate easy placement in tight spots, such as in some import vehicles (FIG. 3). Remove only the flange(s) that are necessary to make the speaker fit the chosen location. Secure the speaker with at least two opposing flanges. In some vehicles, you may have to bend or angle (but not break) one of the two flanges to get the proper fit when installing the speakers in your dashboard. To remove flanges, use tin snips. Do not use a sander or grinder, as that could cause fine metal shavings to fall into the voice coil and driver suspension units.

LOW FREQUENCY CUT-OFF FOR SYSTEMS WITH SUBWOOFERS

If you have a subwoofer in your system, you may want to decrease the amount of bass frequencies going to your mid-range speakers (which is what your “full range” speakers would be if you had a subwoofer in your system). Doing this will result in better mid-range detail and increased 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 amplifier and the other end connected to the positive lead of each of your speakers (FIG. 4). Bass blocker capacitors (200 microfarad @ 100volts, non-polarized) are available at most car stereo dealers, RadioShack and parts supply stores. The other route is to use an electronic crossover device that allows filtering below 100Hz or so. You can find these devices at your authorized Polk Audio dealer.
