Infinity Reference REF697MF 6"x9" Coaxial Speakers

Product Overview

Bring fuller mid-bass and more detail to your car audio system with the Infinity Reference REF697MF 6"x9" three-way coaxial speakers. Their oversized Plus One+ woofer, dedicated tweeter, and supertweeter extend the sound range without requiring a separate subwoofer.

Key Features & Benefits

• Three-way design: A 1" edge-driven textile dome tweeter and textile semi-dome supertweeter reproduce detail across the high frequencies.
• Plus One+ woofer: The oversized polypropylene cone moves more air than a standard 6"x9" woofer for deeper, punchier bass.
• Hi-roll rubber surround: Supports controlled cone movement for consistent bass response over time.
• +3 dB tweeter boost: Lets you add high-frequency presence when a lower door mounting position affects the sound.
• Efficient output: The 94 dB sensitivity rating helps produce strong output from a given power level.
• Up to 100W RMS: Power handling gives you room to pair the speakers with a capable amplifier.

Technical Specifications

Why Choose This Product?

The REF697MF combines a larger woofer cone with two high-frequency drivers, giving you bass and treble detail from one coaxial speaker pair. Its tweeter boost switch offers an adjustment for installations where the speakers sit lower in the doors.

The stated impedance technology is designed to present a true 4-ohm load to the head unit or amplifier. That can help keep the source unit within its intended operating range when choosing speakers for a system.

Installation & Compatibility Notes

Check the 3.075" top-mount depth against the available space behind your doors or factory panels before installation. The speakers are designed to fit behind factory grilles or panels in most installations; grilles are not included.

The box includes mounting hardware and adhesive-backed foam gaskets. Confirm your intended head unit or amplifier setup and speaker fitment before purchase.
