Kenwood KFC-W2541 10" 4-Ohm Component Subwoofer

The Kenwood KFC-W2541 is a 10-inch, 4-ohm component subwoofer designed to add low-frequency output to a vehicle audio system. It is intended for listeners who want deeper bass than factory full-range speakers can produce. As a passive subwoofer, it is installed in a suitable enclosure and powered by a compatible external amplifier.

With 300 watts RMS power handling and a 33 to 300 Hz frequency response, the KFC-W2541 is built for dedicated bass reproduction. Its 84 dB sensitivity specification provides useful context when matching it with an amplifier and enclosure. The single 4-ohm configuration keeps system planning straightforward for a compatible mono or subwoofer amplifier channel.

Kenwood uses an injection polypropylene X-motif cone with a Diamond Array Pattern to help control resonance. The speaker also incorporates a stress-controlled spider, which is computer optimized to manage mechanical stress during operation. These design elements support consistent movement of the woofer assembly when reproducing bass material.

Thermal management is addressed through an aluminum bobbin, closed-yoke design, and advanced airflow control. The closed-yoke structure is paired with a ferrite magnet and steel basket. Together, these components form a durable platform for a custom subwoofer enclosure installation.

The KFC-W2541 can be used in either a sealed or ported enclosure based on the desired system approach. Kenwood specifies a 0.65-cubic-foot sealed enclosure or a 0.9-cubic-foot ported enclosure. It is also identified by Kenwood as a power match for the KAC-D5101 amplifier, making it a practical option for a matched Kenwood bass upgrade.

Key Features

• 10-Inch Subwoofer: Adds dedicated bass capability to a custom vehicle audio system.
• 300W RMS Handling: Supports amplifier matching for sustained bass playback.
• 4-Ohm Impedance: Simplifies pairing with compatible mono amplifier channels.
• X-Motif Cone: Helps control resonance for solid bass response.
• Thermal Management: Aluminum bobbin and airflow design manage heat.
• Dual Enclosure Options: Supports Kenwood-specified sealed or ported box designs.

Design & Installation

The KFC-W2541 uses a steel basket, ferrite magnet, urethane surround, ABS gasket, paper diaphragm, and injection polypropylene cap. Its special features include the injection PP X-motif cone with Diamond Array Pattern, closed yoke with advanced airflow control, aluminum bobbin, and stress-controlled spider. The speaker measures 10-13/16 inches wide and high, with an overall depth of 5-5/8 inches.

Plan the enclosure and vehicle location before installation. The subwoofer requires a 9-1/16-inch cutout diameter and 4-7/8 inches of mounting depth, while Kenwood specifies 0.65 cubic feet for a sealed enclosure or 0.9 cubic feet for a ported enclosure. Use a compatible external amplifier and wiring installation appropriate for a 4-ohm passive subwoofer; the optional CA-101G grille is available separately.
