JL Audio CS112G-TW3 Sealed Car Subwoofer Enclosure

570,00 €

The JL Audio CS112G-TW3 is a sealed car subwoofer enclosure for adding bass to a car audio system. Its 2 Ω nominal impedance helps you select a suitable amplifier output, while its 400 W RMS rating provides a continuous power handling figure for comparison. The black-carpeted enclosure measures 365 mm wide, 413 mm high and 267 mm deep. A protective grille is included.

Description

JL Audio CS112G-TW3 is a sealed car subwoofer enclosure designed to add bass to a car audio system. Before choosing it, check three things: whether your amplifier can drive its 2 Ω nominal load, how its 400 W continuous power handling (RMS) relates to the amplifier’s output, and whether the complete enclosure will fit in your car. The enclosure is finished in black carpet, and a protective grille is included.

What the sealed enclosure means

The sealed enclosure is part of this product. You do not need to find a separate box for the subwoofer or decide what type of box to build. When planning its position, measure the space needed for the complete enclosure rather than judging it by the visible speaker alone.

Black carpet covers the enclosure. Before settling on a position, consider how it will stand and whether it will interfere with everyday use of the boot. The protective grille covers the speaker side. This matters particularly if you carry other items in the same space. The grille provides a barrier, but the position should still leave it clear of anything that might press against it.

Choosing and setting up an amplifier

The 2 Ω nominal impedance is the key figure when matching this enclosure with an amplifier. Choose an amplifier output that can operate with a 2 Ω load. If your existing amplifier is intended only for higher impedances, it is not suitable for this model.

400 W RMS describes the enclosure’s continuous power handling. It does not mean the subwoofer will always draw or use that amount of power. When comparing amplifiers, look at their continuous output ratings at 2 Ω. A prominently advertised maximum power figure alone does not tell you how an amplifier will perform when connected to this enclosure.

Start with a modest amplifier level, then blend the bass with the rest of the car’s speakers. If the amplifier has a low-pass filter, begin with a setting that keeps clearly audible vocal frequencies out of the subwoofer. Make further adjustments while listening to music you know well. The bass should support the main speakers without overwhelming them or drawing attention away from the vocals.

If your system offers phase or time-alignment controls, assess their effect from the driver’s seat. Change one setting at a time and listen for a more even transition between the bass and the other speakers around the frequencies where they meet. The controls available to you depend on the amplifier or audio processor in your system.

Finding a place in the car

The enclosure measures 365 mm wide, 413 mm high and 267 mm deep. Use these external dimensions to check the intended location. Allow room for the connection and position the enclosure so that the grille is not pressed against another surface.

Its 12.7 kg net weight also matters when choosing a position. Select a place where the enclosure can stand steadily. Before completing the installation, try the proposed position and listen from the driver’s seat. Moving a sealed enclosure closer to a boot wall can change how much bass you hear. Check the route into the boot as well: an enclosure may fit its intended position but still be difficult to pass through the boot opening.

FAQ

What amplifier should I choose for this enclosure?

Look for an amplifier with an output rated to handle a 2 Ω load. When assessing power, compare continuous output figures at the same impedance rather than maximum power figures presented on different terms.

Can I connect it directly to my car stereo?

That depends on what the stereo’s outputs can drive. This enclosure has a 2 Ω nominal impedance and needs an amplifier output suitable for that load. A signal output alone cannot power the speaker.

How should I start blending its bass with my other speakers?

Begin with a low amplifier level and enable a low-pass filter if one is available. Adjust gradually while listening to a familiar recording. Aim for bass that fills out the sound without distracting from the vocals.

Can I use it in a system with multiple subwoofer enclosures?

In a multiple-enclosure system, the total load presented to the amplifier matters. If you add a second enclosure, you cannot assess the combination using only the 2 Ω impedance of one enclosure. Choose the wiring arrangement according to the load your amplifier permits.

What should I check before putting it in the boot?

Check that the complete enclosure will pass through the boot opening, even if there is enough room for it in the chosen position. Also consider how much space will remain for the items you carry every day.

How can I protect the grille side when carrying other items?

Position the enclosure so that carried items do not rest against or press on the protective grille. Leave a separate space for those items even though the speaker side is covered.
