JL Audio CS110LG-TW1-2 Subwoofer Enclosure

The JL Audio CS110LG-TW1-2 subwoofer enclosure is a low-profile automotive bass system designed for installations where space is limited. Its enclosure contains one 10-inch 10TW1-2 subwoofer driver. With a depth of only 141 mm, it is easier to find a suitable installation location inside a vehicle.

Continuous power handling is rated at 300 W RMS, while the system has a nominal impedance of 2 ohms. It therefore requires an external amplifier that can operate correctly with this load.

A Preassembled System for Your Vehicle

The system is supplied assembled, internally wired, and ready for use. Installation involves selecting a suitable position, securing the enclosure, and connecting the speaker cable from the amplifier.

The low-profile PowerWedge design helps make effective use of shallow installation areas where the available space is restricted.

Construction and Protection

The sealed enclosure is made from CNC-cut, high-grade MDF panels. It does not have a bass-reflex port, so installation does not require additional clearance for a port opening.

The exterior is finished in black automotive-grade carpet. A silver embroidered JL AUDIO logo complements the understated appearance, while the carpeted surface blends naturally with the type of trim commonly found in vehicle luggage compartments.

A black steel-mesh protective grille is included. It covers the installed driver and reduces the likelihood of direct contact with the subwoofer cone.

Connecting the Amplifier

The system connects through a five-way binding-post terminal. The internal speaker wiring has already been completed, so there is no need to open the enclosure. The speaker cable coming from the amplifier connects directly to the external terminal.

The recommended amplifier power range is 75 to 300 W. When choosing an amplifier, check its output rating into a 2-ohm load. A power figure quoted at a different impedance does not show whether the amplifier is suitable for this enclosure.

The RMS figure describes sustained power handling rather than a volume setting. Amplifier gain must be adjusted according to the source signal. Excessive gain can produce audible signal distortion.

Choosing an Installation Location

The enclosure requires a flat, stable mounting surface. Its overall size and 7.90 kg weight must both be considered when planning the installation. The side fitted with the protective grille must remain unobstructed.

Leave enough room behind the terminal for the cable and its natural bending radius. This prevents the cable from being compressed against the vehicle trim and keeps the connection accessible if the system needs to be disconnected later.

The final bass balance is affected by the shape of the vehicle cabin and the position of the enclosure. Before securing it permanently, compare several locations that are practical for installation. Evaluate each position while listening from the normal driving seat.

Integrating It with the Vehicle Audio System

This passive enclosure does not contain an integrated amplifier or adjustment controls. System tuning is carried out on the external amplifier. Use its low-pass filter, gain control, and phase setting where those functions are available.

Adjust the low-pass filter to complement the frequency range reproduced by the vehicle’s main speakers. The aim is a smooth transition between the speakers and the subwoofer, not bass that sounds excessively prominent or detached from the rest of the system. Make changes in small steps and compare the results at the same listening volume.

If the amplifier offers multiple phase settings, compare them from the driver’s seat. Keep the setting that allows the bass to blend more naturally with the front speakers. The preferred setting depends on the actual installation position inside the vehicle.

Technical Specifications

FAQ

Is this a separate subwoofer driver?

No. The package includes the enclosure, an installed and internally wired subwoofer driver, and the protective grille. A separate external amplifier suitable for a 2-ohm load is also required.

How should I choose a suitable amplifier?

Check the amplifier’s continuous power output at the enclosure’s nominal impedance. Its output should fall within the specified recommended power range. Do not judge suitability solely by the amplifier’s maximum short-term power figure.

Can the enclosure be connected directly to a car stereo?

No. It requires an external power amplifier. A car stereo’s subwoofer output can provide a signal to the amplifier, but it cannot power the enclosure by itself.

Where is the most convenient place to install it in a vehicle?

Choose a location that accommodates the complete enclosure while keeping the connection terminal accessible. Do not place objects directly against the protective grille. Compare several possible enclosure positions before securing it permanently.

Is a separate low-pass filter required?

Filtering is normally handled by the external amplifier or the vehicle’s audio processor. Adjust the filter to suit the main speakers so that their frequency ranges join smoothly.

Is this enclosure intended for a home stereo or home cinema system?

No. It is designed for automotive audio systems. In a vehicle, it supplements the main speakers through a separate external amplifier.
