CA-SK03057ET

The CA‑SK03057ET is a pair of 5×7″ coaxial car speakers from Carbon Audio’s ET Series, designed as a direct aftermarket upgrade for factory door or rear deck speakers. These full‑range speakers are engineered to deliver clearer, louder, and more dynamic audio than many stock speaker installations, making them a solid choice for everyday listening and improved in‑car sound quality. 

5×7″ Coaxial Design: Two 5 × 7″ speakers with integrated tweeters for balanced midrange and high‑frequency response. 

Power Handling: ~90 W RMS continuous power per speaker with up to ~300 W peak capability, supporting stronger output when paired with moderate amplification. 

4 Ω Impedance: Standard 4‑ohm impedance ensures compatibility with most car stereos and aftermarket amplifiers. 

Wide Frequency Range: Designed to reproduce sound from roughly 78 Hz to 20 kHz, providing a full listening experience across music genres. 

Carbon Fiber Cone: High‑strength carbon fiber‑reinforced cone improves durability while helping provide crisp response and reduced distortion. 

Efficient Sensitivity: Around 86 dB sensitivity helps the speakers produce strong output even with moderate power. 

Shallow Mounting Depth (~55 mm): Allows for easier installation in many 5×7″ or 6×8″ speaker cutouts where space is limited.
