Infinity REF467F 4x6" 2-Way Coaxial Car Speakers

The Infinity REF467F is a pair of 4x6-inch, 2-way coaxial car speakers designed to replace worn or limited factory speakers in compatible vehicle locations. Its compact format is intended for standard 4x6-inch applications while delivering a broader, more detailed presentation than many original-equipment speaker systems. This is a practical option for drivers building a straightforward front- or rear-speaker upgrade.

Each REF467F speaker is rated for 45 watts RMS and 135 watts peak power handling. With 92 dB sensitivity at 2.83V and a 3-ohm nominal impedance, the pair is designed to work in automotive audio systems that can provide clean, appropriate power. The rated frequency response is 75 Hz to 21 kHz, covering core midrange and high-frequency content while leaving the deepest bass to a dedicated subwoofer if desired.

The 2-way coaxial layout combines a woofer and tweeter in each speaker assembly, helping simplify installation where the vehicle uses a single 4x6-inch speaker location. Infinity Reference speakers use edge-driven textile tweeters intended to reproduce smooth, clear high frequencies. This makes the REF467F well suited to listeners looking for clearer vocals, percussion, and upper-frequency detail from a compact replacement speaker.

Infinity's Plus One woofer cone architecture uses increased cone area compared with conventional cones in its class. The additional radiating area is designed to support sensitivity, low-frequency output, and midrange performance within the available mounting footprint. The REF467F also uses a compact, optimized frame intended to help it fit a broad range of factory speaker locations.

For a balanced system, the REF467F can be used with a factory radio or an aftermarket receiver or amplifier that is compatible with its impedance and power requirements. An amplifier should be selected and adjusted with the 45-watt RMS-per-speaker rating in mind rather than the peak rating. Confirm speaker-opening dimensions, mounting depth, cutout size, wiring polarity, and vehicle-specific installation requirements before purchase.

Key Features

• 4x6-Inch Coaxial Format: Fits compatible compact factory speaker locations.
• 2-Way Speaker Design: Combines woofer and tweeter in each speaker.
• 45W RMS Handling: Supports appropriately matched aftermarket amplification.
• Edge-Driven Textile Tweeter: Designed for smooth, clear high-frequency playback.
• Plus One Woofer Architecture: Uses increased cone area for efficient output.
• Optimized Frame Size: Compact basket design aids factory-location fitment.

Design & Installation

The REF467F uses Infinity Reference-series engineering, including edge-driven textile tweeters, Plus One woofer cone architecture, and an optimized speaker frame. Its 4x6-inch coaxial construction keeps the woofer and tweeter together in a single assembly, making it appropriate for locations that do not provide separate tweeter mounts. The speaker's specified external dimensions are 6-3/16 by 3-15/16 inches, with a total depth of 2-3/16 inches.

Verify that the vehicle has adequate clearance for the 1-7/8-inch mounting depth and a compatible 5-9/16 by 3-3/8-inch mounting cutout. Install each speaker with correct positive and negative polarity, use the supplied foam mounting tape as appropriate, and check whether vehicle-specific adapters, brackets, harnesses, or fasteners are needed. The package includes one pair of coaxial speakers and an owner's manual; confirm fitment before installation.
