Audio Code AC-25x 2.5" High-Frequency Tweeter

The Audio Code AC-25x 2.5" High-Frequency Tweeter is a compact, high-grade tweeter engineered for crisp, distortion-free high-frequency reproduction in active multi-way systems and component speaker builds. Sold individually. The AC-25x handles the upper frequency spectrum in a 2-way or 3-way active system, delivering the sparkling highs and fine detail that midrange drivers and subwoofers can't reproduce — completing the full-range soundstage in a custom car audio build.

The AC-25x is a dedicated high-frequency tweeter — it is designed to be crossed over and used as part of an active or passive multi-way system alongside a midrange driver and subwoofer. The high-grade diaphragm delivers sharp, distortion-free high-frequency reproduction that brings out the fine detail and air in your music — the cymbal shimmer, vocal sibilance, and upper harmonic content that lower-frequency drivers simply can't resolve. The ultra-compact 2.5" frame slots into custom dash pods, A-pillar locations, and factory tweeter locations without modification in most vehicles. The 4-ohm nominal impedance is compatible with virtually any amplifier channel. Sold individually — order two for a stereo pair.

Use the AC-25x as the high-frequency driver in an active 2-way or 3-way system: cross it over with a high-pass filter at 4–6kHz to protect the tweeter from midrange frequencies that could damage the diaphragm. Pair with a dedicated midrange driver (such as the Audio Code AXC NEO 6 or ZRO 6) and a subwoofer for a complete active system. Drive with a dedicated amplifier channel or a DSP amplifier with active crossover capability. Contact us at Trinity Car Audio for system design guidance.

System Integration Recommendations

The AC-25x is a dedicated tweeter — it must be used with an active or passive crossover. Always apply a high-pass crossover at 4–6kHz to protect the tweeter diaphragm from midrange frequencies. In a 3-way active system, pair with a dedicated midrange driver (such as the Audio Code AXC NEO 6, ZRO 6, or ZR05) and a subwoofer for full-range coverage. Drive with a dedicated amplifier channel or a DSP amplifier with active crossover capability. Sold individually — order two for a stereo pair.

Frequently Asked Questions

Q: Is the AC-25x sold as a pair or individually?
A: The AC-25x is sold individually — one tweeter per order. Order two for a stereo pair.

Q: Do I need a crossover for the AC-25x?
A: Yes — always use a high-pass crossover at 4–6kHz to protect the tweeter diaphragm from midrange frequencies. Running a tweeter without a crossover can damage or destroy the diaphragm. A DSP amplifier with active crossover capability is the ideal solution.

Q: What midrange driver pairs best with the AC-25x?
A: The AC-25x pairs naturally with Audio Code midrange drivers including the AXC NEO 6, AXC ZRO 6, AXC ZR05, and AXC NEO 5. Contact us at Trinity Car Audio for a complete system design recommendation based on your vehicle and goals.

Q: Where can I mount the AC-25x in my vehicle?
A: The ultra-compact 2.5" frame fits custom dash pods, A-pillar locations, sail panel locations, and factory tweeter cutouts in most vehicles. Contact us at Trinity Car Audio for mounting guidance specific to your vehicle.
