Cerwin-Vega CVP10S4 10" 4-Ohm Subwoofer

The Cerwin-Vega CVP10S4 is a 10-inch passive car subwoofer designed to add dedicated low-frequency output to an aftermarket vehicle audio system. Its single 4-ohm voice coil provides a straightforward load for a compatible amplifier. It is intended for drivers who want to build or refresh a bass system with a separate subwoofer and enclosure.

With 150 watts RMS and 450 watts maximum power handling, the CVP10S4 is suited to amplifier matching based on continuous power rather than peak ratings. Its 87.1 dB sensitivity and 8 mm one-way Xmax support responsive bass performance within its operating limits. The 10-inch format can be a practical option where enclosure space is more limited than a larger subwoofer installation.

A polypropylene cone and treated foam surround form the moving assembly. The surround uses a dual-stitched connection and ribbed design intended to support cone movement. A structure-reinforcing dust cap is also used as part of the driver assembly.

The CVP10S4 uses a ferrite magnet motor, stamped-steel basket, and perimeter-vented voice-coil design. Its bumped backplate is engineered to allow increased excursion, while the venting supports heat dissipation. Large-gauge spring terminals simplify connection of speaker wire during installation.

This subwoofer can be used in sealed or ported enclosures, allowing the system design to be tailored to available space and listening goals. A sealed enclosure is commonly selected for a more compact installation, while a ported enclosure changes the system's output character. Confirm enclosure dimensions, amplifier capability, and vehicle clearances before installation.

Key Features

• 10-Inch Subwoofer: Adds dedicated bass without requiring a larger driver format.
• Single 4-Ohm Voice Coil: Provides simple amplifier and wiring compatibility.
• 150W RMS Handling: Supports appropriate continuous-power amplifier matching.
• Polypropylene Cone: Uses a light, rigid cone material.
• Perimeter Voice-Coil Venting: Helps dissipate heat during operation.
• Stamped-Steel Basket: Provides a stable mounting structure for the driver.

Design & Installation

The CVP10S4 combines a polypropylene cone, treated foam surround, ferrite magnet, and CAD-optimized stamped-steel basket. Its dual-stitched, ribbed surround and structure-reinforcing dust cap are part of the driver design. The subwoofer uses large-gauge spring terminals for speaker-wire connections.

Plan for a 236 mm mounting diameter, 253 mm hole diameter, and 134 mm mounting depth when designing the enclosure and checking vehicle clearance. Pair the subwoofer with an external amplifier compatible with a 4-ohm single-voice-coil load and size the amplifier around its 150-watt RMS rating. Use it in a properly designed sealed or ported enclosure; an enclosure and amplifier are required for operation.
