The
Infinity Reference REF507CF is a
premium 5.25-inch, 2-way component car speaker system designed to deliver high efficiency, clear vocals, and detailed high frequencies as a major factory upgrade.
Key Technical Specifications
-
Power Handling: 65 Watts RMS per speaker (130W per system) | 195 Watts Peak per speaker (390W per system).
-
Impedance: 3-Ohm architecture (safely combines with factory wiring for a true 4-ohm load to pull extra power from your source).
-
Sensitivity: 93 dB at 2.83V.
-
Frequency Response: 67 Hz – 21,000 Hz.
-
Woofer Mounting Depth: 1.9 inches (ideal for shallow factory locations).
Core Performance Features
-
Plus One™ Polypropylene Cones: Patented design offers a larger cone surface area than standard 5.25" speakers, providing enhanced bass and stronger midrange response.
-
Edge-Driven Textile Tweeters: Delivers smooth, crisp highs that maintain clarity without distortion or listener fatigue even at high volumes.
- Adjustable Tweeter Output: Includes an integrated crossover level control switch (+0 dB / +3 dB) to optimize linear performance depending on your vehicle's installation placement.
Electrical & Acoustic Specifications
-
Continuous Power Handling (RMS): 65 Watts per speaker (130 Watts total per matching system pair).
-
Peak Power Handling: 195 Watts per speaker (390 Watts total per matching system pair).
-
Nominal Impedance: 3.0 Ohms. Designed with True Four Ohm Impedance technology, the speaker’s low impedance intentionally safely combines with factory-installed high-gauge speaker wiring to present a safe 4-ohm load to your aftermarket or factory head unit, optimizing power extraction.
-
Sensitivity: 93 dB measured at 2.83 Volts.
-
Frequency Response: 67 Hz to 21,000 Hz.
Transducer Architecture
-
Mid-Woofer Driver: Features a 5-1/4" (5.25-inch) patented Plus One™ Polypropylene cone. This design increases the overall active cone surface area relative to standard baskets in its size class, resulting in higher low-frequency acoustic output and greater midrange tracking accuracy.
-
Woofer Surround: Constructed with high-roll rubber to support extended linear cone excursion.
-
Tweeter Assembly: Uses 3/4" (0.75-inch) edge-driven textile dome tweeters. This construction lowers distortion and prevents high-frequency acoustic break-up compared to traditional balanced-dome configurations.
Crossover Network & System Tuning
-
Passive Filters: Outboard 2-way crossover networks isolate proper frequencies to respective drivers.
-
Tweeter Attenuation Control: Integrated switch allows system optimization with a selectable 0 dB or +3 dB boost level to compensate for off-axis or low-door speaker positioning.
Physical Dimensions & Mounting Data
-
Top-Mount Depth: 1-15/16" (1.9 inches).
-
Cutout Diameter: 4-1/2".
-
Frame Dimensions: 5.077" x 5.077".
- Tweeter Integration: Shipped with Starfish™ brackets for easy alignment inside shallow factory structural mounts, alongside surface and flush-mount alternative housings.
