Cerwin-Vega SM69F4 6x9" Marine 2-Way Coaxial Speakers

The Cerwin-Vega SM69F4 is a pair of 6 x 9-inch, 2-way coaxial speakers made for marine, motorcycle, and powersports audio installations. It provides a flush-mount speaker option for systems exposed to sun, moisture, wind, and open-air riding noise. The 4-ohm design is suited to compatible aftermarket amplifiers and speaker outputs.

Each system combines a 6 x 9-inch woofer section with a 25 mm titanium dome tweeter. This configuration is designed to cover midrange and high-frequency information from one mounting location. Its specified frequency response is 60 Hz to 18 kHz.

The SM69F4 is rated for 150 watts RMS and 300 watts peak power handling. A 93 dB sensitivity rating at 1W/1m supports useful output from an appropriately matched amplifier. The extended-excursion design lists 4 mm of Xmax.

For outdoor durability, Cerwin-Vega specifies an IP65 marine-grade-compliant design with 100% UV-stable materials. The speaker uses a thermal-molded, UV-coated waterproof composite injection cone and a high-temperature injection-molded composite basket. These construction details are intended for marine and powersports environments rather than conventional protected cabin installations.

Integrated digital RGB LED lighting lets the speakers become part of a coordinated illuminated audio system. Cerwin-Vega identifies the optional RPMDLED multi-function digital RGB LED lighting remote control for lighting control. With its 8.64 x 6.0-inch cutout requirement and 3.15-inch mounting depth, the SM69F4 is suited to custom panels, boat surfaces, fairings, and compatible lid installations with sufficient clearance.

Key Features

• 6 x 9-Inch Coaxial Design: Combines woofer and tweeter sections in one flush-mount speaker.
• 25 mm Titanium Dome Tweeter: Handles high-frequency reproduction in the 2-way system.
• 150W RMS Power Handling: Supports amplification matched to the speaker's continuous rating.
• IP65 Marine-Grade Compliance: Supports use in marine and exposed powersports installations.
• Waterproof Composite Cone: Uses UV-coated composite construction for outdoor durability.
• Integrated Digital RGB LEDs: Adds selectable lighting capability with the available RPMDLED controller.

Design & Installation

The SM69F4 uses a thermal-molded, UV-coated waterproof composite injection cone, a titanium dome tweeter, and a high-temperature injection-molded composite basket. Its Radial Zip Ring cone design is specified for expanded high-frequency reproduction, while the Max Xmax suspension design is intended for marine and motorcycle-fairing applications. The speakers are supplied as a pair and use a 4-ohm nominal impedance.

Confirm a mounting opening of 8.64 x 6.0 inches and allow at least 3.15 inches of mounting depth before installation. Use a stable mounting surface and wire each speaker to an amplifier or source compatible with a 4-ohm load and the stated power rating. Plan RGB lighting wiring separately if lighting control is desired; Cerwin-Vega lists the RPMDLED controller as available, and grilles are listed as an option.
