Infinity Reference REF697MF 6"x9" Coaxial Speakers

Infinity Reference REF697MF 6x9 3-way coaxial speakers built for car audio enthusiasts who want deeper bass and extended high-end without a subwoofer, thanks to the Plus One+ oversized woofer and a three-way design.

• Three-Way Coaxial Design: A dedicated 1" edge-driven textile dome tweeter plus a textile semi-dome supertweeter delivers clear highs and added air across the treble range.
• Plus One+ oversized polypropylene woofer cone: Moves more air than a standard 6x9, producing deeper, punchier bass without needing a separate subwoofer.
• Hi-roll rubber surround: Supports controlled cone movement for durable, consistent bass response over time.
• +3 dB tweeter boost switch: Allows compensation for less-than-ideal mounting locations, helping you preserve high-frequency presence when the speakers sit lower in the door.
• True Four Ohm Impedance technology: A 3-ohm voice coil with vehicle wiring yields a true 4-ohm load to the head unit or amplifier, promoting compatibility with most factory or aftermarket source units and reducing risk of overloading the radio's internal amp.
• Power handling: Handles up to 100W RMS (300W peak), giving you headroom to pair with a capable amplifier for cleaner, louder output.
• Frequency response: 46–30,000 Hz, enabling strong bass through the low end and extended highs for detailed imaging.
• Sensitivity: 94 dB @ 2.83V, indicating efficient output for a given power level and good loudness from a moderate amp.
• Top-mount depth: 3.075", a factor to consider for fit behind factory panels or doors in many applications.
• Grilles: Not included, designed to fit behind factory grilles or panels in most installations.
• Warranty: 1 year.
• What's in the box: Two 3-way speakers, two bottom mount rings, mounting screws and speed clips, two adhesive-backed foam gaskets, instruction manual.

In a typical car audio build, the REF697MF pair provides substantial mid-bass and high-frequency presence without a subwoofer, especially when driven by a suitable amplifier. The supertweeter and boost switch help tailor the top end for door-mounted installations, while the 4-ohm load compatibility keeps the head unit or amplifier within its comfortable operating range. The included mounting hardware and gasket set simplify installation behind factory panels in many vehicles.
