Focal 10 WM<\/strong> is a standalone 25 cm subwoofer driver designed for the low-frequency section of a car audio system. It is not a complete, ready-to-use subwoofer enclosure. Installation requires a suitable cabinet, an external amplifier, and low-pass filtering.<\/p>\n

The 400 W nominal power rating<\/strong> is the main reference point when selecting an amplifier. The 800 W figure indicates maximum power and must not be treated as a continuous operating rating. Two 4 \u03a9 voice coils provide additional wiring options, but the resulting load must always be compatible with the amplifier.<\/p>\n

Construction and Its Purpose<\/h2>\n

The W-type cone<\/strong> is paired with a butyl surround. The surround is the flexible connection between the moving cone and the stationary part of the driver. It allows the cone to move as the subwoofer reproduces low frequencies.<\/p>\n

The voice coil diameter<\/strong> is 120 mm. This measurement should not be confused with the required mounting cutout or the overall diameter of the driver. The voice coil former is made from fibreglass, while the winding uses a two-layer construction.<\/p>\n

The voice coil is wound with copper-clad aluminium wire<\/strong>, commonly identified as CCAW. This describes the material used for the coil winding, not the cable used to connect the driver to an amplifier. The grey driver weighs 8.10 kg, so the front panel of the enclosure must be strong enough to support its weight securely.<\/p>\n

Voice Coil Wiring and Amplifier Load<\/h2>\n

The 4+4 \u03a9<\/strong> designation means that the driver has two separate 4 \u03a9 voice coils. Connecting the coils in parallel produces an approximately 2 \u03a9 nominal load for the amplifier. Connecting them in series produces an approximately 8 \u03a9 load.<\/p>\n

Use a parallel connection only when the amplifier channel is stable with a 2 \u03a9 load. A series connection is appropriate when the amplifier requires a higher load. The polarity must remain consistent across both voice coils, regardless of the selected wiring arrangement.<\/p>\n

The specified 3.1+3.1 \u03a9 DC resistance<\/strong> is not an alternative system impedance rating. A measured voice coil resistance is normally lower than its nominal impedance. Amplifier matching and wiring decisions should therefore be based on the stated 4+4 \u03a9 specification.<\/p>\n

Amplifier and Filter Setup<\/h2>\n

This driver does not contain a built-in amplifier or control panel. Low-frequency filtering, output level, and phase adjustment must be handled by an external amplifier or audio processor. The low-pass filter should be set in conjunction with the vehicle\u2019s main speakers so that the frequency ranges do not overlap unnecessarily.<\/p>\n

Begin with a low gain setting and listen from the normal driving position. Increase the level gradually until the bass supports the main speakers without overpowering them. Compare the available phase or polarity settings and choose the option that produces the smoothest result around the selected crossover frequency.<\/p>\n

Enclosure and Installation Location<\/h2>\n

The 25 cm size class identifies the general category of the driver, but it does not guarantee compatibility with an existing enclosure. Before installation, compare the required cutout diameter, mounting depth, and fastening positions. These dimensions cannot be determined from the 25 cm designation alone.<\/p>\n

Enclosure volume and bass-reflex port dimensions cannot be selected from the power ratings alone. They depend on the electromechanical parameters of the specific driver. An unsuitable enclosure volume will alter the system\u2019s frequency balance and the operating conditions of the cone.<\/p>\n

Because the driver weighs 8.10 kg, it requires a rigid front baffle and secure mounting. Sufficient clearance must be left around the surround so that the moving cone cannot touch trim panels or other nearby surfaces. The completed enclosure must also be firmly secured inside the vehicle.<\/p>\n

FAQ<\/h2>\n

Is this a ready-to-use subwoofer?<\/h3>\n

No. It is a standalone driver that must be installed in a properly calculated enclosure. It also requires an external amplifier and equipment capable of filtering the audio signal.<\/p>\n

How should the two voice coils be wired?<\/h3>\n

Parallel wiring produces an approximately 2 \u03a9 nominal load, while series wiring produces an approximately 8 \u03a9 nominal load. The correct arrangement depends on the permitted channel load of the amplifier.<\/p>\n

Should I select an amplifier based on the 800 W rating?<\/h3>\n

No. Match the amplifier primarily to the driver\u2019s 400 W nominal power rating. The maximum rating does not represent continuous operation.<\/p>\n

Will the driver fit my existing 25 cm enclosure?<\/h3>\n

The size class alone is not enough to confirm compatibility. The mounting cutout, installation depth, and fastening positions must match. The enclosure volume must also be suitable for this particular driver.<\/p>\n

Where are the crossover frequency and phase adjusted?<\/h3>\n

These settings are adjusted on the external amplifier or audio processor. Evaluate the result from the driver\u2019s seat while listening to the subwoofer together with the vehicle\u2019s main speakers.<\/p>\n

Can it be used in a home stereo or cinema system?<\/h3>\n

Electrical connection would require an amplifier compatible with the resulting load and a specially designed enclosure. This driver belongs to the car audio equipment category and is not an active home loudspeaker.<\/p>\n

Can two of these drivers be installed in one system?<\/h3>\n

Every additional driver changes the total load presented to the amplifier. The voice coil wiring, amplifier power, and enclosure construction must therefore be recalculated. The package contains one driver.<\/p>\n","protected":false},"excerpt":{"rendered":"
