Pioneer TS-WX120A Active Car Subwoofer
229,00 €
Pioneer TS-WX120A is an active subwoofer for a car audio system. Its 20 × 13 cm speaker has an aluminium diaphragm, while the adjustable 50-125 Hz low-pass filter helps blend its bass with the system’s other speakers. The 280 × 70 × 200 mm enclosure dimensions help you assess installation space. A wired controller can be placed away from the enclosure.
Pioneer TS-WX120A is an active subwoofer for a car audio system. It uses a 20 × 13 cm speaker with an aluminium diaphragm to add low frequencies to the sound from the car’s other speakers. One side of the enclosure measures 70 mm, but that figure alone cannot tell you whether the unit will fit in a particular space. Compare all three external dimensions with the space available before choosing an installation position. An adjustable low-pass filter and a wired remote control provide ways to tune and control the bass.
Construction and installation space
The speaker’s construction includes an aluminium diaphragm, a copper coil and a magnet marked Y-35. When planning an installation, the enclosure’s size, its 3.6 kg weight and access to the controller are the more useful practical details to consider.
The enclosure measures 280 × 70 × 200 mm. The order of these sides is not identified, so do not assume from the numbers alone which measurement represents its height. Check the available space against the complete enclosure and allow for the route of the wired remote control. Its cable is 6 m long; the distance along the route you intend to use matters more than a straight-line measurement to the control position.
A recommended sealed-box volume of 2.2 l is also stated for this subwoofer. This is an acoustic enclosure volume, not a measure of how much free space the unit needs inside the car. Use the external enclosure dimensions when assessing where it can be placed.
Adjusting the bass
The built-in low-pass filter can be adjusted from 50 to 125 Hz. It reduces higher frequencies at 12 dB per octave. This adjustment helps the subwoofer work with the car’s other speakers by controlling how much their reproduced frequencies overlap. The best setting depends on those speakers and on where the subwoofer is installed.
Start with a lower filter setting and listen to a recording you know well from the driver’s seat. If you hear a gap between the bass and the sound from the main speakers, raise the filter cutoff gradually. If low sounds become too easy to locate at the subwoofer’s position, try lowering the cutoff. Listen for a smooth transition through the whole system, since a number on the control cannot tell you how the speakers will sound together in your car.
The wired remote control lets you place the controller away from the subwoofer enclosure. Choose a position that is convenient to reach, then check the full cable route to that position. Bends and the path through the car can make the required cable length greater than the direct distance between the two points.
Understanding the power and frequency figures
The stated nominal input power is 50 W. A figure of 150 is given for maximum input power, but no unit of measurement is supplied with it. It should therefore not be treated as a confirmed 150 W specification or compared directly with another model’s power rating.
The stated 30-160 Hz frequency range indicates the part of the sound spectrum this subwoofer is intended to reproduce. Measurement limits are not provided for that range, so it does not show how loudly the unit reproduces each frequency within it. The listed sensitivity is 98 dB without measurement conditions, and the lowest resonant frequency is 76.6 Hz. These figures provide context, but listening to the complete system is more useful when choosing an installation position and filter setting.

FAQ
What is this subwoofer for?
It is designed to add low frequencies to a car audio system. Its active design means the amplifier section is built into the unit.
Does the 4 Ω impedance mean I need a separate amplifier?
No. This is an active model, and the 4 Ω figure describes its speaker load. That figure alone does not identify the type of connection it uses with a car stereo.
How should I choose a filter setting?
Adjust it while listening from the driver’s seat. Aim for a smooth transition between the main speakers and the subwoofer, without an obvious overlap in the frequencies they reproduce.
Where can I install the wired controller?
Choose a place you can reach comfortably and that the 6 m cable can reach. Measure along the cable route you plan to use.
Does 2.2 l tell me how much space the unit needs in the car?
No. It is the recommended sealed acoustic enclosure volume. Use the external enclosure dimensions to assess the space needed in the car.
Can I connect this model to my existing car audio system?
The information provided is not enough to determine that, because the connector types are not specified. Before buying, compare your car audio system’s connections with those on this model and ask the store for connector information if needed.
Is this model intended for a home stereo or cinema system?
It is classified as car audio equipment. For a home system, choose a model whose power supply and connections are intended for your home equipment.
