Hifonics 5x7/6x8 2-Way Coaxial Car Speakers, Pair

Hifonics Zeus ZS5768CX are 5x7/6x8" two-way coaxial car speakers delivering up to 250W peak power with Mylar dome tweeters and alpha-cellulose woofers for clear highs and tight mid-bass.

These coaxial speakers from Hifonics combine a lightweight Neo-Mylar dome tweeter with robust alpha-cellulose woofers and a copper voice coil to produce balanced sound for factory replacements or budget upgrades. Designed for resilient everyday use, the speakers include features that manage heat and moisture while the passive Butterworth crossover smooths the handoff between woofer and tweeter. They fit common 5x7 and 6x8 openings and are sold as a pair for easy left/right installation.

How do these speakers improve my car’s soundstage?

The Zeus ZS5768CX separates frequencies so vocals and instruments come through more distinctly than many stock speakers. The Neo-Mylar tweeter handles high frequencies with lower distortion while the alpha-cellulose woofer focuses on mid-bass clarity. Together, they create a fuller, more detailed soundstage across typical commuting volumes.

• Two-way coaxial layout improves stereo imaging and clarity.
• Mylar soft dome reduces harshness in high frequencies.
• Alpha-cellulose cone balances responsiveness and natural tone.
• Passive Butterworth crossover ensures smooth frequency transitions.

Are these speakers durable enough for daily driving?

Yes — Hifonics built these speakers with materials and assembly choices aimed at durability in a vehicle environment. The moisture-resistant rubber surround protects the cone edge from humidity, while the epoxy-infused natural fiber spider adds strength and flexibility to handle cone excursion. Heat management is improved by a pure copper voice coil and Kapton former that dissipate thermal energy during extended listening sessions.

• Rubber surround resists moisture and maintains cone stability.
• Epoxy-infused natural fiber spider provides long-lasting flexibility.
• Copper voice coil and Kapton former improve heat dissipation.
• Solid build tolerates daily vibration and temperature changes.

What are the power and technical specifications I should know?

The pair is rated for 90W RMS and 250W peak power handling, making them suitable for many factory and aftermarket head units or modest amplifiers. Sensitivity is about 88 dB (1W/1m), so they reproduce good volume without excessive power. Frequency response extends up to 20 kHz, letting the Mylar dome capture upper detail while the woofer covers mid-bass duties.

• RMS power handling: 90W per speaker.
• Peak power handling: 250W per speaker.
• Sensitivity: 88 dB (1W/1m) for efficient output.
• Frequency response up to 20 kHz for crisp highs.

How easy is installation and what should I prepare?

These coaxial speakers are intended as plug-and-play replacements for many 5x7 and 6x8 applications, making installation straightforward for DIYers and installers. Confirm mounting depth and hole dimensions in your vehicle before purchase, and have basic tools and wiring connectors on hand. If your factory connectors differ, adapter pigtails speed up the swap without cutting factory harnesses.

• Direct-fit for many 5x7 and 6x8 speaker openings.
• Check mounting depth and bolt pattern for compatibility.
• Use connector adapters to avoid modifying factory wiring.
• Pair works equally for driver and passenger sides.

Who is this for: The Hifonics Zeus ZS5768CX pair suits drivers seeking a reliable, budget-friendly upgrade from factory speakers who want clearer highs and stronger mid-bass without adding external crossovers or large amplifiers. Installers and DIY enthusiasts will appreciate the proven materials, heat-aware voice coil design, and the straightforward fit for many 5x7/6x8 applications. Choose these if you want improved tonal balance and everyday durability in a compact, two-way coaxial package.
