Hifonics ZS5768CX 5x7/6x8" 2-Way Coaxial Speakers

The Hifonics ZS5768CX is a pair of 5x7/6x8-inch two-way coaxial car speakers designed for replacing compatible factory door, rear-deck, or panel-mounted speakers. They provide a straightforward upgrade path for vehicles using this common oval speaker format. A supplied 6x8-inch adapter plate helps support installation in applicable 6x8-inch locations.

Each speaker is rated for 90 watts RMS and 250 watts peak power handling at 4 ohms. With an 88 dB sensitivity rating and a 46 Hz to 20 kHz frequency response, the pair is suited to factory-radio replacement systems as well as properly matched aftermarket amplification. The coaxial layout places the tweeter within the woofer assembly to combine midrange, bass, and high-frequency reproduction in one mounting position.

The sound design combines an Alpha-Cellulose poly woofer cone with a 1-inch Neo-Mylar soft-dome tweeter. The rigid, lightweight cone is intended to support responsive midbass performance, while the soft-dome tweeter handles upper-frequency detail. A passive Butterworth crossover directs frequencies between the woofer and tweeter for a controlled transition.

Hifonics uses a pure-copper voice coil on a lightweight Kapton former, with an overcoil cooling arrangement that exchanges air through the spider area. The epoxy-infused natural-fiber spider is designed to balance flexibility with structural support. A ferrite magnet motor and stamped-steel basket provide the foundation for the speaker assembly.

The ZS5768CX is a practical choice for listeners upgrading worn or limited factory speakers without moving to a separate component-speaker system. Its moisture-resistant rubber surround and high-temperature adhesive support use in typical vehicle environments. Pair it with a compatible 4-ohm factory or aftermarket audio channel, while confirming vehicle-specific mounting depth, cutout, and wiring requirements before installation.

Key Features

• 5x7/6x8-Inch Fitment: Fits the stated speaker size category and includes a 6x8-inch adapter plate.
• Two-Way Coaxial Design: Integrates the woofer and tweeter into each speaker assembly.
• 90W RMS Handling: Supports 90 watts RMS and 250 watts peak per speaker.
• Neo-Mylar Tweeter: A 1-inch soft-dome tweeter delivers high-frequency reproduction.
• Alpha-Cellulose Woofer Cone: Lightweight, rigid cone material supports responsive midbass performance.
• Passive Butterworth Crossover: Helps transition frequencies between the woofer and tweeter.

Design & Installation

These speakers use an anti-resonant stamped-steel basket, ferrite magnet motor, pure-copper voice coil, Kapton former, and epoxy-infused natural-fiber spider. The woofer uses an Alpha-Cellulose cone with a moisture-resistant rubber surround and high-temperature adhesive. No speaker grilles are included, reflecting their intended use in many factory replacement locations where the vehicle already provides a grille.

Confirm that your vehicle accepts 5x7-inch or 6x8-inch speakers and verify both the mounting cutout and depth before ordering. The listed chassis depth is 2.13 inches, and the quick-start guide lists a 4.92 x 7.09-inch cutout measurement. Use the included 6x8-inch adapter plate where appropriate, connect using the spade terminals or soldered connections, and match the speakers to a compatible 4-ohm audio channel.
