Description

Product Overview

Bring balanced sound to your car with the Hifonics ZS525CX ZEUS 5.25-inch 2-way coaxial speaker pair. Alpha-cellulose woofer cones, moisture-resistant rubber surrounds, and 1-inch Neo-Mylar soft dome tweeters handle low and high frequencies in one speaker assembly.

Use them to replace or upgrade speakers in standard 5.25-inch car audio locations that meet the stated cutout and depth requirements.

Key Features & Benefits

Two-way coaxial design: A woofer and tweeter in each speaker cover mid-bass through high frequencies.
Alpha-cellulose cones: The lightweight, rigid cone material supports responsive mid-bass.
Moisture-resistant rubber surrounds: The surrounds couple to the cones and are designed to resist moisture.
Neo-Mylar soft dome tweeters: The 1-inch tweeters deliver high-frequency output, while their impact-resistant elements are designed for reliability.
Overcoil cooling: Air exchanges over the voice coil through the spider to help manage heat during playback.
Protective grilles included: Use the grilles when the speakers are not mounted behind vehicle panels.

Tweeter details	1 inch; clear highs while handling plenty of power without sounding harsh. Neo-Mylar soft dome tweeter elements are impact resistant.
Kapton	Lightweight and efficiently dissipates heat.
Cone details	Alpha-cellulose cones are lightweight for speed and rigid for deep bass.
Surround / cone coupling	Moisture-resistant rubber surround with high mid-bass impact. High-temperature adhesive creates a permanent bond between the cone and surround.
Voice coil / former assembly	Pure copper creates a strong magnetic field with a very thin extrusion. Kapton is lightweight and efficiently dissipates heat.
Spider	Epoxy-infused natural fiber; the natural fiber allows flexibility, while the epoxy gives strength during manufacturing.
Cooling system	Overcoil: air is exchanged over the voice coil through the spider.
Crossover	Passive Butterworth; smooth transition of frequencies from midrange/midbass to the tweeter element.
Frame	Anti-resonant stamped steel basket; strong, with minimal harmonics or distortion from flex or ringing.
Motor	Ferrite magnet creates a strong magnetic field while remaining small enough to fit nearly every application.
Connectors	Spade; use spade connectors or solder direct for the best connection.
Grilles	Yes; protects the speaker from accidental damage. Not used if the speaker is mounted behind a vehicle panel.
Compatibility	Standard 5.25-inch (13.3 cm) car audio speaker locations requiring an 11.4 cm cutout diameter and at least 5.1 cm of mounting depth.
What's included	Pair of Hifonics ZS525CX 5.25-inch coaxial speakers; protective speaker grilles; quick start guide.

Why Choose This Product?

The ZS525CX combines its woofer and tweeter in a 2-way coaxial layout, making both frequency ranges part of one speaker assembly. A passive Butterworth crossover transitions frequencies from the midrange and mid-bass to the tweeter.

Its stamped steel basket, pure copper voice coil, Kapton former, and overcoil cooling system are specific design choices for this speaker. Check the power handling and 4-ohm impedance against your audio system when selecting a replacement or upgrade.

Installation & Compatibility Notes

These speakers are described for standard 5.25-inch (13.3 cm) car audio locations with an 11.4 cm cutout and at least 5.1 cm of mounting depth. Compare those measurements with your available space before installation.

The connectors are spade type; the source also states that direct soldering can be used. Protective grilles are included, but are not used when the speakers are mounted behind vehicle panels.
