Frequently Asked Questions - FXW-122 SPL

How do I connect the subwoofer to my receiver?

Use a subwoofer cable to connect the Sub Out port on your receiver to the Line In jack on the subwoofer. Alternatively, you can use the speaker-level inputs if your receiver lacks a sub out.

Where should I place the subwoofer for best performance?

Place the subwoofer in a corner or against a wall to reinforce bass. Avoid placing it in the center of the room. Experiment with placement to reduce standing waves.

What is the correct setting for the crossover frequency?

Set the crossover frequency to around 80 Hz for typical home theater. Adjust higher for smaller speakers (e.g., 120 Hz) or lower for larger speakers. Fine-tune by ear.

Why is the subwoofer not producing any sound?

Check power and signal connections. Ensure the subwoofer is powered on and the volume is turned up. Verify that your receiver's subwoofer output is enabled. Also, check the phase switch setting.

How do I adjust the phase setting?

The phase switch (0° or 180°) corrects timing alignment with main speakers. Play a bass-heavy track and switch between positions; choose the one that produces the loudest, tightest bass.

Can I use this subwoofer with a car audio system?

This subwoofer is designed for home use with AC power. For car use, you would need a DC-to-AC inverter and a suitable amplifier, which is not recommended.

What is the maximum power handling?

The RMS power handling is 200 watts. Peak power may be higher, but continuous operation at high levels may cause distortion or damage.

How do I clean the subwoofer?

Unplug the subwoofer and wipe the cabinet with a soft, dry cloth. Do not use any liquids or harsh chemicals. The driver cone can be dusted gently.

The subwoofer makes a humming noise. What should I do?

Humming is often caused by a ground loop. Ensure all audio components share the same power strip. Try a different outlet or use a ground loop isolator on the signal cable.

Is the subwoofer repairable?

Yes, basic repairs like replacing the amplifier module or driver are possible. Contact SPL customer support for service options. Do not attempt internal repairs yourself.

Enclosure Dimensions

Included in this manual are a number of different enclosure suggestions. These are by no means the only enclosures to use, but the provide a starting point to determine the correct enclosure for your needs many factors must be addressed (amount of power, vehicle, placement, crossovers, etc) Therefore, as always, SPL recommends that your subwoofer be installed by an authorized SPL dealer.

Enclosure Construction

All enclosures should be made of .75" (3/4") material only. When possible, make the baffle 1.5" (1 12 ) thick and add .75" (3/4") to the depth of the enclosure to compensate. All volumes INCLUDE vent/port and subwoofer displacements. DO NOT change the volume unless you plan on adding a substantial amount of bracing. For added performance, applying a coat of fiberglass resin to the interior walls will greatly improve sealing the enclosure. Adding a thin layer of poly-fill will improve response by smoothing out reflections within the enclosure.
