Infinity REF697F 6x9" 2-Way Coaxial Car Speakers

The Infinity REF697F is a pair of 6x9-inch, 2-way coaxial car speakers designed as a direct sound-quality upgrade for compatible factory speaker locations. They combine a woofer and tweeter in each speaker, making them a practical option for vehicles that use 6x9-inch openings. Their compact frame is engineered to support installation in a broad range of vehicles.

These speakers are suited to drivers who want clearer high frequencies, stronger midrange presence, and more low-frequency output than worn or basic factory speakers can provide. With 100 watts continuous power handling and 94 dB sensitivity at 2.83V, they can be used with compatible factory or aftermarket audio systems. An external amplifier may be used when its output is properly matched to the speakers.

The REF697F uses edge-driven textile dome tweeters to reproduce upper-frequency detail with a smooth character. The tweeter output can be adjusted by 3 dB, allowing the high-frequency balance to be tailored for the mounting location and listening preference. This is useful when speaker placement makes the system sound overly bright or subdued.

Infinity's Plus One+ woofer cone architecture increases effective cone area compared with conventional cones in the same class. The polypropylene woofer cone and hi-roll rubber surround are designed to support controlled movement and everyday automotive durability. Together, these elements help the speaker cover its rated 46 Hz to 20 kHz frequency response range.

As a coaxial pair, the REF697F provides a straightforward path for upgrading front or rear speaker positions that accept 6x9-inch speakers. Its 3-ohm nominal impedance is intended to work with typical vehicle speaker wiring as part of Infinity's True Four Ohm Impedance approach. Confirm vehicle-specific fitment, mounting clearance, and wiring requirements before installation.

Key Features

• 3-Ohm Nominal Impedance: Designed for compatibility with common vehicle audio systems.

Design & Installation

The REF697F uses a polypropylene Plus One+ woofer cone with a hi-roll rubber surround, paired with a 1-inch textile edge-driven dome tweeter. Its 2-way coaxial layout places the tweeter at the center of the woofer assembly, while the optimized basket design is intended to fit many factory speaker locations. The speakers have an external frame size of 9-5/16 by 6-7/16 inches and a total depth of 3-5/8 inches.

Check the vehicle's speaker opening, mounting depth, panel clearance, and factory connector arrangement before purchase. The required mounting cutout is 8-1/2 by 5-3/4 inches, and mounting depth is 3-1/8 inches. The package includes two speakers, two spacers, mounting screws, speed clips, foam mounting tape, and an owner's manual; vehicle-specific harness adapters, brackets, wiring, or an amplifier may be needed separately.
