Frequently Asked Questions - B-8APR Sound Ordnance
How do I connect the B-8APR subwoofer to my receiver?
Use a mono RCA cable from the subwoofer output on your receiver to the Line In on the subwoofer. Alternatively, you can use speaker level inputs if your receiver lacks a subwoofer output.
What is the best placement for the subwoofer?
Place it in a corner or along a wall for enhanced bass. Avoid placing it in the center of the room. Experiment with the phase switch to integrate with your main speakers.
How do I adjust the crossover frequency?
Set the crossover knob to match your main speakers' low-frequency limit. Typically, start at 80 Hz for home theater. Adjust based on your preference and the room acoustics.
Why is my subwoofer not turning on?
Check if the power cord is plugged in and the power switch is on. Ensure the auto on/off feature is detecting a signal. If using auto mode, play some audio to trigger it.
Can I use this subwoofer in a car?
No, this subwoofer is designed for home use with AC power (110-120V). It is not suitable for 12V car systems.
What does the phase switch do?
The phase switch (0 or 180 degrees) adjusts the timing of the subwoofer's output relative to your main speakers. Set it to the position that produces fuller, more coherent bass at your listening position.
How do I clean the subwoofer?
Use a soft, dry cloth to wipe the cabinet. For the grille, gently vacuum with a brush attachment. Never use liquid cleaners or spray directly on the unit.
What is the maximum power handling?
The built-in amplifier provides 150 watts RMS. Do not connect an external amplifier to the driver as it may damage the subwoofer.
Does the subwoofer have a warranty?
Yes, it typically comes with a 1-year limited warranty from Sound Ordnance. Keep your receipt for service claims.
Can I daisy-chain multiple subwoofers?
If your receiver has multiple subwoofer outputs, you can connect each subwoofer individually. Otherwise, use a Y-splitter to connect two subwoofers to one output, but ensure the total impedance load is acceptable.
