Infinity Reference REF607F 6.5" Coaxial Speakers

The Infinity Reference REF607F is a 6.5" two-way coaxial speaker designed as a direct factory-upgrade that delivers stronger midbass and a natural, detailed high end. Its Plus One+ oversized polypropylene woofer cone and edge-driven tweeter with level control are built for an accurate, versatile listening experience in real car installs.

• Plus One+ oversized polypropylene woofer cone: Moves more air than a conventional 6.5" woofer, boosting midbass and adding fullness to the low-mid range for a more impactful overall sound.
• Hi-roll rubber surround: Keeps the cone controlled and durable over years of use, improving long-term performance and reducing distortion at higher output.
• 1" textile edge-driven dome tweeter with 3.0 dB level adjustment: Delivers clear highs with low fatigue; the 3 dB adjustment helps tailor the soundstage when mounting positions vary in the door.
• True Four Ohm Impedance technology: Operates as a 3-ohm speaker plus wire to present a true 4-ohm load to the head unit, ensuring broad compatibility with factory or aftermarket sources without impedance mismatch.
• Power handling: Handles up to 60W RMS (180W peak), providing ample headroom for everyday amplifications and musical transients without overdesigning the system.
• Frequency response: 52–21,000 Hz for a wide range from bass fundamentals through crisp treble, supporting a cohesive front-stage image.
• Sensitivity: 93 dB @ 2.83V, indicating relatively efficient output from a standard head unit or modest amplification.
• Top-mount depth: 2.44" for compatibility with a variety of vehicle housings and dash/door voids.
• Grilles: Grilles are not included; designed to fit behind factory grilles or panels in most applications, with optional grilles available for custom installations.
• Warranty: 1 year.
• What’s in the box: Two 2-way speakers, mounting hardware, 2 adhesive-backed foam gaskets, instruction manual.

Benefits: This pair is well suited for upgrading factory-supplied 6.5" speakers in vehicles where a natural soundstage and stronger midbass are desired without additional processing. The 4-ohm-compatible design works with virtually any source unit, avoiding impedance issues while delivering efficient, musical output. The combination of a robust woofer, durable surround, and adjustable tweeter allows you to tailor the front stage for a more cohesive, engaging listening experience across genres—from hip-hop to rock to podcasts—while keeping installation practical and reliable.
