Hifonics HCC35CX 3.5" 2-Way Coaxial Car Speakers

The Hifonics HCC35CX is a pair of 3.5-inch, 2-way coaxial car speakers designed to replace compatible factory speakers in compact dash, door, or rear-panel locations. They provide a straightforward upgrade path for vehicles whose original small speakers sound worn, dull, or limited in detail. With a 4-ohm design and 25 watts RMS handling per speaker, they are suited to factory radios and modest aftermarket amplification.

A blue woven-fiber woofer cone handles the midrange, while the centrally mounted 1-inch aluminum dome tweeter reproduces upper frequencies. The stated 80 Hz to 20 kHz frequency response supports clear vocal and instrument detail across the speakers' intended operating range. Their 88 dB sensitivity helps them produce useful output from moderate power.

The HCC35CX uses a passive Butterworth crossover network to divide the signal between the woofer and tweeter. Its specified 6 kHz crossover point and 12 dB slope are intended to provide a controlled transition between the two drivers. This coaxial arrangement keeps both drivers together in a compact speaker footprint.

Construction includes butyl rubber surrounds, an epoxy-infused natural-fiber spider, and an anti-resonant stamped-steel basket. A ferrite magnet motor structure and pure copper voice coil provide the speaker's motor system. The voice coil uses a Kapton former and an overcoil cooling design to help manage heat during operation.

These speakers are a practical choice for replacing 3.5-inch factory locations where space is limited and a full component system is unnecessary. They are sold as a pair, allowing both speakers in a matched location to be upgraded together. Confirm the vehicle's opening size, available depth, mounting pattern, and wiring arrangement before installation.

Key Features

• 3.5-Inch Coaxial Design: Combines woofer and tweeter in one compact speaker assembly.
• 25W RMS Per Speaker: Matches moderate-power factory and aftermarket audio systems.
• Woven-Fiber Cone: Supports controlled midrange reproduction in a lightweight driver.
• Aluminum Dome Tweeter: Extends high-frequency reproduction to the stated 20 kHz limit.
• Passive Butterworth Crossover: Directs frequencies between the woofer and tweeter.
• Overcoil Cooling System: Helps dissipate voice-coil heat during extended listening.

Design & Installation

The HCC35CX combines a stamped-steel basket with a ferrite magnet motor, butyl rubber surround, epoxy-infused natural-fiber spider, and braided tinsel leads. Its woofer uses a blue woven-fiber cone, while the 1-inch dome tweeter uses aluminum. No speaker grilles are included.

Verify a 3.41-inch cutout and at least 1.5 inches of top-mount depth at the intended location before ordering. The speakers support spade-terminal connections or direct soldering, so vehicle-specific adapters, mounting hardware, or wiring adapters may be needed depending on the installation. Use a compatible 4-ohm amplifier or head-unit speaker output and avoid exceeding the 25-watt RMS rating per speaker.
