Autotek Street Machine SM525CX 5.25" 2-Way Coaxial Speakers – 250 Watts
The Autotek SM525CX 5.25-inch coaxial speakers are engineered to provide a high-fidelity, high-impact audio upgrade for your vehicle’s factory speaker locations. As part of the Street Machine series, these speakers utilize Alpha-Cellulose poly cones, which offer a perfect blend of rigidity and lightweight performance to produce rich midrange and punchy mid-bass. The high-frequency detail is handled by oversized 1-inch Neo-Mylar soft dome tweeters, delivering soaring, crystal-clear highs while remaining resistant to the harsh temperature swings of a car interior. With an anti-resonant stamped steel basket and a built-in passive Butterworth crossover, the SM525CX ensures a smooth, musical transition between frequencies for a balanced and immersive listening experience.
