Frequently Asked Questions - T-Sub-AX15B Wharfedale

How do I connect the Wharfedale T-Sub-AX15B to my audio system?

Use a balanced XLR cable from your mixer's subwoofer output to the sub's input. Alternatively, use RCA cables if your source has an RCA output. Ensure the subwoofer's volume is turned down before powering on.

What is the optimal placement for the subwoofer?

Place the subwoofer on the floor, preferably in a corner or against a wall to enhance low-frequency response. Avoid placing it in the middle of the room. Keep it at least 6 inches away from walls for proper port ventilation.

How do I set the crossover frequency?

Adjust the crossover knob to match your main speakers' low-frequency limit. A typical setting is around 80 Hz. The crossover is a low-pass filter, so frequencies above the set point are sent to the main speakers.

Why is the subwoofer not producing sound?

Check that the power cord is plugged in and the power switch is on. Verify the input cable is connected properly. Ensure the subwoofer's volume is turned up. Also, check that the signal source is sending a low-frequency signal.

Can I use the subwoofer in a portable PA system?

Yes, the T-Sub-AX15B is designed for both installed and portable applications. It has a robust build and handles high SPL. Ensure adequate ventilation and do not exceed the rated power.

What is the phase switch for?

The phase switch (0° or 180°) corrects phase alignment between the subwoofer and main speakers. Experiment with both positions to hear which gives a fuller, more coherent bass response at your listening position.

How do I clean the subwoofer?

Use a soft, dry microfiber cloth to wipe the cabinet. For stubborn dirt, slightly dampen the cloth with water. Do not use any chemical cleaners, alcohol, or abrasive materials as they may damage the finish.

What type of fuse does the subwoofer use?

The subwoofer uses a standard 5x20 mm glass fuse. The rating is indicated on the fuse holder. Replace only with the same amperage and voltage rating (e.g., T3.15A L250V). If the fuse blows repeatedly, consult a qualified technician.

Is the subwoofer compatible with 100V line systems?

No, the T-Sub-AX15B is designed for standard low-impedance audio systems (4 or 8 ohms). It is not a 100V line speaker. Use with a suitable amplifier only.

What is the warranty period?

Wharfedale typically offers a 2-year warranty for passive speakers and 1-year for active electronics. Confirm with your dealer. The warranty covers manufacturing defects but not damage from misuse or unauthorized repairs.

Everyone loves bass!

That is exactly why we have created the T-Sub-AX15B - our all-new new 700 w Continuous, 1400 w Peak 15" active subwoofer.

The internal Class D amplifier delivers huge output power into the custom quad-layer 15" Wharfedale Pro LF driver to produce extreme subs and low end pressure into any system.

Built for big bass, the plywood constructed cabinet is rock solid and is protected in durable Rhino Rock paint.

You'll not only 'feel' the T-Sub-AX15B, but you will also see it! A new illuminated WP logo badge subtly glows and adds to the overall on-stage "power" of the new T-Sub.

T-Sub-AX15B is the perfect companion for a Typhon, a Titan or a Tourus Wharfedale Pro active loudspeaker.

Hold on to your socks!

T-Sub-AX15B is going to blow them off!

SETTING UP

1. Ensure the mains switch is in the off position.
2. Set the level control to minimum (Fully anticlockwise).
3. Connect all signal cables.
4. Connect the power cable.
5. Switch on source equipment, ensuring that the master level is at minimum.
6. Switch on the T-Sub-AX15B subwoofer.
7. Raise the level control on the T-Sub-AX15B.
8. If the limit LED illuminates lower the level control, if more level is required you will need more speakers. Occasional flashes are acceptable.
9. When powering down your system ensure that the level control has been lowered to minimum before switching off the power.
