Frequently Asked Questions - SUB8SM Theater Solutions
How do I connect the SUB8SM subwoofer to my AV receiver?
Connect the subwoofer's RCA line-in to the subwoofer output or LFE channel on your AV receiver. Alternatively, use the speaker-level inputs by running wires from the receiver's speaker terminals to the subwoofer. Make sure the volume is turned down before making connections.
Where should I place the subwoofer for best bass?
Place the subwoofer along the same wall as the front speakers and at least a few inches from the wall. Corner placement increases bass output, but can make it boomier. Leave the front port clear of obstructions and avoid enclosures that trap sound.
What crossover setting should I use?
Set the crossover frequency to about 80 Hz for most home theater systems, or match it to the lowest frequency your other speakers can reproduce. If you have small bookshelf speakers, a higher setting such as 100-120 Hz may blend better.
How do I use the phase switch?
The phase switch (0° or 180°) aligns the subwoofer's driver movement with that of your main speakers. Listen to music with strong bass and switch between positions. Choose the setting that gives the fullest, most natural bass at your listening position.
Why is there no sound coming from the subwoofer?
Check that the power cable is plugged in, the power switch is on, and the LED indicator lights up. Verify the connection to the LFE/RCA input and that the receiver's subwoofer output is enabled. Increase the volume control on the subwoofer and play a bass-heavy track.
Can I use the subwoofer with a stereo amplifier?
Yes, if your stereo amplifier has a pre-out or subwoofer output, connect it with a single RCA cable. If not, use the speaker-level inputs on the subwoofer, connecting them in parallel with the main speakers. Make sure all connections are secure and correct polarity.
How do I clean and maintain the subwoofer?
Unplug the subwoofer before cleaning. Wipe the cabinet and port with a soft, dry cloth. Do not use water, chemical cleaners, or spray liquids. Clean the grille gently to avoid damaging the woofer cone.
What should I do if the subwoofer hums?
A hum is usually caused by a ground loop or poor cable shielding. Check that all audio components are plugged into the same wall outlet or power strip. Try a different RCA cable and avoid routing signal cables near power cords. If the hum continues, a ground loop isolator may help.
Is the subwoofer safe to leave in standby mode?
Yes, the subwoofer's standby mode is designed to save power when no signal is detected. If you are away for a long period, it is safer to turn off the unit at the power switch or unplug it to protect against electrical surges.
Does the subwoofer require special speaker cables?
Standard 16-gauge speaker wire is sufficient for normal home use. For long cable runs, use thicker wire such as 14-gauge. Ensure the stripped ends are clean and firmly tightened in the binding posts to avoid short circuits.
