settings—Crossover: 70Hz, High-Pass: 12dB, and Low-Pass: 24dB. The optimal setting for these options may vary depend- ing on your room and listening preferences. Experiment and listen for what sounds best to you.

7If you have completed steps 1–5 and still have weak or booming bass consider adjusting the 25Hz Level knob to compensate for these anomalies. Experiment with the controls and listen to the result. Try to find a position that sounds cor- rect to you. Experiment by changing the Level control while adjusting this knob. Find a position that gives you deep extended bass and good blending with your main speak- ers. If you still have weak or booming bass you may want to move your subwoofer’s location and go through these setup steps again (especially if the sub is located in or near a room corner). Remember, room position has a major impact on overall bass performance.

Using Speaker Level Inputs

This connection method is recommended if your subwoofer will be used in a 2-channel only system with full-range front loud- speakers. To connect using Speaker Level Input the speaker cable should be terminated using banana style plugs. The Low- Pass Filter knob is applied to the signal received through these inputs. If the Custom Low-Pass button is activated it will override the Low-Pass Filter knob.

Speaker Level Inputs are an alternative to using RCA or XLR inter- connects. If you use the Speaker Level Inputs do not use RCA or XLR at the same time for Left In / Right In connections. If you use

the Speaker Level Inputs it is okay to still use RCA or XLR for the LFE connection.

Connect the left and right outputs of your amplifier to the sub- woofer’s Speaker Level Input (Left In/Right In). Use quality speaker cable and banana plugs. Be consistent and make sure the + and – terminals from your amplifier are attached to the matching + and – terminals on the subwoofer.

If your amplifier only has one set of outputs you may connect your amplifier to your speakers as normal and run an addition- al set of cables from your speakers to the subwoofer’s Speaker Level Input.
