Focal ACX 165 S | Auditor Series 6.5" 2-Way Shallow Coaxial Speakers
The Focal ACX 165 S is an ultra-slim 165 mm (6.5") coaxial kit designed for vehicles with restricted mounting depth. As part of the Auditor EVO line, these speakers bring Focal's legendary French engineering to an entry-level price point. With a mounting depth of only 48.5 mm (1.9 in.), they are specifically built to "disappear" into shallow door panels while providing a significantly more dynamic and neutral sound compared to factory equipment.
Product Highlights
-
Ultra-Shallow Design: One of the slimmest 6.5" speakers on the market, making it the "go-to" solution for vehicles like the Toyota Tacoma or Subaru where space behind the door panel is limited.
-
Mylar Inverted Dome Tweeter: A hallmark of Focal DNA, this tweeter design offers excellent spatial dispersion and a wide soundstage, ensuring clear highs even when mounted low in a door.
-
Polypropylene Cone: Provides a neutral, natural tonal balance with the high rigidity required for punchy mid-bass and reduced distortion.
-
High Sensitivity: Rated at 91 dB, these speakers are highly efficient and can be easily driven by a factory head unit, though they truly shine when paired with a dedicated amplifier.
Key Features
-
Integrated Crossover: The high-fidelity crossover is built directly onto the basket, simplifying installation by eliminating the need to mount external boxes.
-
Butyl Rubber Surround: Ensures long-term reliability and resistance to the harsh automotive environment (heat and humidity) while maintaining consistent cone movement.
-
Black Lacquer Finish: The tweeter is finished in a sleek black lacquer, allowing it to blend seamlessly into modern vehicle interiors.
-
Rigid Steel Basket: A durable, vibration-resistant frame provides a solid foundation for the motor, ensuring clean audio reproduction at higher volumes.
