Description

Product Overview

Get a two-way speaker upgrade into a shallow door cavity with the Infinity Reference REF607FSL 6.5-inch shallow-mount coaxial speakers. The pair combines a Plus One+ polypropylene woofer with a 1/2-inch textile balanced-dome tweeter for midbass and clear high-frequency detail in a compact installation.

Key Features & Benefits

Shallow-mount design: A 1.78-inch top-mount depth suits tight spaces where standard-depth speakers may not fit.
Plus One+ woofer: Its polypropylene cone has more surface area than a standard 6.5-inch cone to move more air for midbass.
Textile dome tweeter: The 1/2-inch balanced dome provides high-frequency extension for detailed listening.
Adapter rings included: The rings help match the speakers to various OEM openings.
True Four Ohm Impedance technology: The 3-ohm speaker and wire create a 4-ohm load for integration with common factory and aftermarket head units.

Why Choose This Product?

The REF607FSL is designed for installations where mounting depth is a key constraint. Its two-way layout keeps a woofer and tweeter in each speaker, while the shallow profile helps make use of tight factory locations.

The 57 Hz lower frequency limit supports bass presence from the 6.5-inch driver. With 55W RMS power handling and 93 dB sensitivity at 2.83V, these speakers are suited to systems using common head units or modest amplifiers.

Installation & Compatibility Notes

Check the available mounting depth and speaker opening before installation. The top-mount depth is 1.78", and the included plastic adapter rings are designed for various speaker openings. Factory grilles are suitable for most applications; separate grilles are not included.

The listed impedance technology describes a 3-ohm speaker plus wire as a 4-ohm load. Confirm that the intended head unit or amplifier is appropriate for the speaker load and power handling.

Frequently Asked Questions
