JL Audio CS112LG-TW3 Sealed Car Subwoofer Enclosure
550,00 €
JL Audio CS112LG-TW3 is a sealed subwoofer enclosure for a car audio system. Its 2 Ω nominal impedance is important when choosing an amplifier, while its 400 W RMS rating describes continuous power handling. Consider its 129 mm depth when planning where it will fit. The enclosure has a black carpet finish, and a black steel mesh protective grille is included.
JL Audio CS112LG-TW3 is a sealed subwoofer enclosure designed to add bass to a car audio system. Before choosing it, check two things: whether your amplifier can operate with its 2 Ω nominal impedance, and whether the enclosure will fit where you intend to place it. Compare its width, height and depth with the available space, then measure the opening through which you will carry it into the car. If it will sit in the trunk, also consider whether the items you normally transport could press against the protective grille.
Enclosure and placement in the car
A sealed enclosure has no bass reflex port, so you do not need to reserve clearance for a port opening. You still need to account for the enclosure’s full external dimensions. Its relatively shallow depth may help when considering a location, but depth alone does not establish whether it will fit. Check the width and height against the trunk opening as well as the space inside. This avoids finding a suitable spot for the enclosure only to discover that you cannot get it there.
Black carpeting forms the enclosure’s exterior finish. A black steel mesh grille is included and covers the speaker side. Consider which way that side will face when planning its position, and leave space so transported items do not press on the grille. The enclosure’s net weight also matters when choosing a location and planning how to secure it. Select a fastening method suited to your vehicle’s equipment.
Choosing and setting up an amplifier
The 2 Ω nominal impedance describes the load presented to the amplifier channel connected to this enclosure. That channel must be suitable for operation with a 2 Ω load. If an amplifier’s power output is stated only at a different impedance, do not compare that figure directly with this enclosure’s power rating. Check the amplifier’s rating at the load it will actually drive.
The 400 W continuous power handling rating (RMS) describes long-term power handling; it is not a promise of a particular loudness level. It also does not mean that an amplifier with exactly that output is required. When selecting an amplifier, look at its output into 2 Ω. Once the system is connected, set the gain so the signal does not distort. A larger amplifier power figure alone does not mean the system will automatically sound louder or better. The source signal, filter settings and tuning in the car all affect the final result.
Blending the bass with other speakers
This enclosure reproduces low frequencies, so use the amplifier or audio processor settings to blend it with the car’s other speakers. If your system has a low-pass filter, start with a moderate setting and adjust it while listening. Aim for bass that supports the front speakers without making voices seem concentrated toward the trunk. The appropriate filter frequency depends on the range reproduced by the other speakers in your system.
If your amplifier offers phase control, compare its settings from your usual listening position. Keep the setting that makes the bass blend better with the front speakers. Phase control, when available, is an amplifier setting rather than a control on this enclosure. If you move the enclosure, listen again and revisit the filter and phase settings. The car’s cabin and the layout of the trunk can change what you hear, even when the equipment remains the same.

FAQ
Can I connect this enclosure to any car amplifier?
Choose an amplifier channel that can operate with a 2 Ω load. If the amplifier is not designed for that impedance, do not connect this enclosure to it.
Does the 400 W rating mean I must use an amplifier with exactly that output?
No. It is the enclosure’s continuous power handling rating. Evaluate an amplifier’s output at 2 Ω, and set the gain properly after connecting the system.
Can I use it in a stereo system with front speakers?
Yes, you can plan a car system that uses this enclosure alongside front speakers, provided the amplifier is suitable for the enclosure’s impedance. Adjust the low-pass filter with the range of the front speakers in mind.
Can I use it with a second subwoofer enclosure?
Yes, but only after planning the combined load on the amplifier. How two enclosures are connected changes the impedance the amplifier sees, so do not decide on the connection method from one enclosure’s rating alone.
Where should I place it in the car?
Choose a location based on the enclosure’s dimensions, the position of its grille and your ability to secure it firmly. Before fastening it in its final position, compare the sound from several possible locations.
Do I need to buy the grille separately?
No. The black steel mesh protective grille is included. It covers the speaker side, so allow space in front of it.
