The Focal 165AS3 is a 3-way component speaker system designed to bring a full, detailed soundstage to your vehicle. By separating the frequencies between a 165 mm woofer, an 80 mm midrange driver, and a tn43 inverted aluminum dome tweeter, this set ensures that bass remains dynamic while vocals and high notes stay crisp and clear. Both the woofer and midrange cones are crafted from a double fiberglass structure (dFS), which provides the necessary rigidity for precise audio reproduction, all supported by lightweight ABS polymer baskets. With a nominal power of 80 W and a maximum capacity of 160 W, these speakers are versatile enough to be powered directly by your head unit or paired with an external amplifier thanks to their 90 dB sensitivity. You can fine-tune the audio to your preference using the tweeter level adjustment, which offers settings of -3, 0, or +3 dB. The system covers a frequency range from 55 Hz to 20 kHz, managed by crossovers with points at 300 Hz and 5 kHz to keep each driver operating in its ideal range. Installation is straightforward with a woofer mounting depth of 62.9 mm and a midrange depth of 42.5 mm, making them compatible with various car door configurations. The package includes protective grilles and multiple tweeter installation accessories to help you find the best placement for your specific interior. This setup is an excellent choice for listeners who want a sophisticated audio experience where every instrument and voice is clearly defined.
