Audio Code AXC-ZRO57 5x7" Midrange Loudspeaker

The Audio Code AXC-ZRO57 5x7" Midrange Loudspeaker delivers 250W RMS power handling at 4 ohms with a frequency response spanning 100Hz to 10kHz — a dedicated midrange driver engineered for active multi-way systems and custom car audio builds in the 5x7" / 6x8" OEM speaker format. Sold individually. The ZRO57 brings ZRO series midrange engineering to the oval speaker format found in a wide range of Ford, GM, Chrysler, and import vehicles, delivering the midrange clarity and upper bass punch that factory oval drivers simply can't match.

The AXC-ZRO57 is a dedicated 5x7" midrange loudspeaker, not a coaxial — it is designed to be crossed over and used as part of an active or passive multi-way system alongside a subwoofer and tweeter. The 5x7" form factor is interchangeable with 6x8" OEM locations, making the ZRO57 compatible with a wide range of factory door, dash, and rear deck locations across Ford, GM, Chrysler, and import vehicle platforms. At 250W RMS power handling, the ZRO57 is built for high-output active system builds without thermal compression at rated power. The 4-ohm nominal impedance is compatible with virtually any amplifier channel. Frequency response spans 100Hz to 10kHz — a focused midrange bandwidth that covers upper bass punch and core midrange presence before handing off to a tweeter above 5–7kHz. Sold individually — order two for a stereo pair.

Use the ZRO57 as the midrange driver in an active 3-way system: cross it over with a high-pass filter at 100–150Hz (to protect it from bass frequencies) and a low-pass filter at 4–6kHz (to hand off to a tweeter). Pair with a dedicated tweeter for the upper frequencies and a subwoofer for the low end. Drive with a dedicated amplifier channel rated 125–250W RMS at 4 ohms.

Why Choose the Audio Code AXC-ZRO57?

• 5x7" / 6x8" OEM Format: Fits the oval speaker locations found in a wide range of Ford, GM, Chrysler, and import vehicles — dedicated midrange performance in a factory-compatible size.
• 250W RMS Power Handling: High-output midrange capability built for active system builds without thermal compression at rated power.
• 100Hz – 10kHz Frequency Response: Focused midrange bandwidth covering upper bass punch and core midrange presence — designed for active crossover use in 3-way systems.
• 4-Ohm Impedance: Compatible with virtually any amplifier channel — no special impedance matching required.
• ZRO Series Engineering: Proven Audio Code ZRO midrange driver design in the oval format — the same high-output midrange philosophy as the ZRO 6 and ZRO 8, adapted for 5x7" / 6x8" locations.
• Dedicated Midrange Design: Engineered for active crossover use — cleaner, more focused midrange reproduction than any coaxial oval driver can deliver at high output levels.
• Audio Xtreme Code Build Quality: Engineered for competition and enthusiast applications where standard oval coaxials fall short on midrange output and clarity.

System Integration Recommendations

The AXC-ZRO57 is a dedicated midrange driver — it must be used with an active or passive crossover. In an active 3-way system: set a high-pass crossover at 100–150Hz to protect the driver from bass frequencies, and a low-pass crossover at 4–6kHz to hand off to a tweeter. Drive with a dedicated amplifier channel rated 125–250W RMS at 4 ohms. Pair with a dedicated tweeter for the upper frequencies and a subwoofer for the low end. A DSP amplifier with active crossover capability (such as the JBL DSP4086) is the ideal signal processing solution. Sold individually — order two for a stereo pair.

Frequently Asked Questions

Q: Is the AXC-ZRO57 sold as a pair or individually?
A: The AXC-ZRO57 is sold individually — one speaker per order. Order two for a stereo pair.

Q: Will the 5x7" ZRO57 fit my 6x8" OEM location?
A: Yes — 5x7" and 6x8" are interchangeable OEM speaker sizes. The ZRO57 fits both 5x7" and 6x8" factory locations. This size is common in Ford, GM, Chrysler, and many import vehicles. Contact us at Trinity Car Audio with your year, make, and model to confirm fitment before ordering.

Q: Do I need a crossover for the AXC-ZRO57?
A: Yes — the ZRO57 is a dedicated midrange driver and must be used with an active or passive crossover. Set a high-pass filter at 100–150Hz and a low-pass filter at 4–6kHz. A DSP amplifier with active crossover capability is the ideal solution.

Q: How does the ZRO57 compare to the AXC-ZRO69?
A: Both are Audio Code ZRO series dedicated midrange loudspeakers at 4 ohms and 250W RMS. The ZRO57 is a 5x7" oval driver (fits 5x7" and 6x8" locations) with 100Hz–10kHz response. The ZRO69 is a 6x9" oval driver with 100Hz–12.5kHz response and wider upper-frequency extension. Choose based on your vehicle's OEM oval speaker size.
