Audio Code AXC ZR05 5.25" Bullet Midrange Loudspeaker

The Audio Code AXC ZR05 5.25" Bullet Midrange Loudspeaker delivers 150W RMS / 300W peak power at 4 ohms with a 93dB sensitivity rating and an integrated bullet phase plug — engineered for high-output midrange reproduction in competition SPL builds, custom door pods, and active multi-way systems. Sold individually. Frequency response spans 200Hz to 16kHz, covering the full midrange band from upper bass presence through the lower treble — one of the widest upper-frequency extensions in the Audio Code midrange lineup.

The AXC ZR05 is a dedicated 5.25" 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 integrated bullet phase plug controls the dispersion pattern of the midrange frequencies, reducing off-axis coloration and improving on-axis clarity and focus — a design feature common in competition SPL and high-output car audio builds. The 5.25" nominal diameter fits standard OEM door, dash, and rear deck locations where a 6.5" driver won't fit, making the ZR05 a practical midrange solution for a wider range of vehicle platforms. At 93dB sensitivity (1W/1m), the ZR05 is the most efficient driver in the Audio Code midrange lineup — delivering exceptional output levels from modest amplifier power, ideal for multi-channel systems where amplifier channels are shared across multiple drivers. The 4-ohm nominal impedance is compatible with virtually any amplifier channel. Power handling is 150W RMS / 300W peak. The 200Hz–16kHz frequency response extends further into the upper frequencies than the ZRO 6 (12kHz) or ZRO6-S (7kHz), giving the ZR05 more high-frequency reach before handing off to a tweeter. Sold individually — order two for a stereo pair.

Use the AXC ZR05 as the midrange driver in an active 3-way system: cross it over with a high-pass filter at 200–250Hz (to protect it from bass frequencies) and a low-pass filter at 6–8kHz (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 4-channel amplifier or a DSP amplifier with active crossover capability.

Why Choose the Audio Code AXC ZR05?

• Integrated Bullet Phase Plug: Controls midrange dispersion for improved on-axis clarity and focus — a competition SPL and high-output build design feature.
• 93dB Sensitivity (1W/1m): The highest sensitivity rating in the Audio Code midrange lineup — exceptional output efficiency from modest amplifier power.
• 200Hz – 16kHz Frequency Response: Wide upper-frequency extension — more high-frequency reach than the ZRO 6 or ZRO6-S before handing off to a tweeter.
• 150W RMS / 300W Peak Power Handling: Built for active system builds without thermal compression at rated power.
• 5.25" Format: Fits OEM door, dash, and rear deck locations where a 6.5" driver won't — practical midrange solution for a wider range of vehicle platforms.
• 4-Ohm Impedance: Compatible with virtually any amplifier channel — no special impedance matching required.
• Audio Xtreme Code Build Quality: Engineered for competition and enthusiast applications demanding high-output, focused midrange reproduction.

System Integration Recommendations

The AXC ZR05 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 200–250Hz to protect the driver from bass frequencies, and a low-pass crossover at 6–8kHz to hand off to a tweeter. Drive with a dedicated amplifier channel rated 75–150W 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 ZR05 sold as a pair or individually?
A: The AXC ZR05 is sold individually — one speaker per order. Order two for a stereo pair.

Q: How does the ZR05 compare to the AXC ZRO 6?
A: The ZR05 is a 5.25" bullet midrange at 150W RMS with 93dB sensitivity and 200Hz–16kHz response. The ZRO 6 is a 6.5" bullet midrange at 250W RMS with 96dB sensitivity and 100Hz–12kHz response. The ZR05 has wider upper-frequency extension (16kHz vs 12kHz) and fits smaller OEM locations; the ZRO 6 handles more power and extends lower. Choose based on your install location and system goals.

Q: Do I need a crossover for the AXC ZR05?
A: Yes — the ZR05 is a dedicated midrange driver and must be used with an active or passive crossover. Set a high-pass filter at 200–250Hz and a low-pass filter at 6–8kHz. A DSP amplifier with active crossover capability is the ideal solution.

Q: What amplifier should I use with the AXC ZR05?
A: A dedicated amplifier channel rated 75–150W RMS at 4 ohms is ideal. In a multi-way active system, a 4-channel or DSP amplifier with active crossover capability is the preferred solution. Contact us at Trinity Car Audio for a complete system design consultation.
