The AUTOCRANK AT3618 is a 6.5-inch (160mm) coaxial car speaker designed for robust audio performance. It features a maximum power handling of 350 watts and an RMS power handling of 60 watts, ensuring it can deliver strong sound output. The speaker uses an injection-molded polypropylene cone, which contributes to durability and sound clarity. It also includes a PEI (Polyetherimide) balanced dome tweeter for clear high-frequency reproduction. The frequency response spans from 55 Hz to 20 kHz, covering a wide range of audio frequencies. With a sensitivity rating of 91 dB (measured at 2.83V and 1 meter), it efficiently converts power into sound. Additionally, the onboard crossover helps to manage the distribution of audio frequencies between the woofer and tweeter, enhancing overall sound quality.
