The speakers are designed with a frequency response of 45 Hz to 20 kHz, ensuring they can reproduce a wide range of audio frequencies. The sensitivity rating of 88 dB means that they can produce a significant volume level with a moderate amount of power. The impedance is 4 ohms, making them compatible with a wide range of car audio amplifiers.

The Autotek SM4cx Street 2-way Coaxial Car Speakers are not only powerful and efficient but also visually appealing. The speakers come with a black polymer grille that blends seamlessly with most car interiors. The mounting depth is 2.12 inches, allowing for easy installation in most vehicles.
