The Z-Series TS-Z65F 6-1/2" coaxial speaker system makes the very best way to add smooth, open, sound quality to your car. Equipped to handle power up to 110 W RMS, Pioneer built the Z-Series to harness that wealth of information and reproduce music incredibly close to the original performance. To ensure a premium audio experience, the Z-Series TS-Z65F uses Twaron, a lightweight, heat-resistant fiber that is exceptionally strong and stable to create a woofer cone that will confidently handle your music's midrange and lows without undesirable resonance. An oversized aluminum dome tweeter reproduces the most demanding tones, while maintaining accuracy in high-level playback. With a frequency range up to 96,000 Hz, enjoy authentic reproduction of your finest recordings, with all the overtones and harmonics making music real. With these gold-trimmed Z-Series speakers installed in your doors, turn up your music with confidence and savor all the nuances you've been craving in the car.
