Alpine built their top-of-the-line Type-X Pro Series component speaker systems from the ground up to bring you uncompromised sound quality. These component speakers offer supreme accuracy and extended response, so you can enjoy "concert hall" sound in your vehicle.

The SPX-13PRO system includes two 5-1/4" woofers, two 1-1/4" ring radiator tweeters, and two outboard crossover networks. The woofer's hybrid glass fibre cone uses a unique cross-ribbed design that increases stiffness and controls resonance, contributing to the speaker's exceptional clarity. A Natural Butyl Rubber surround provides a solid suspension for the woofer cone, while the cast aluminum frame eliminates flexing and unwanted vibrations. A patent-pending cooling system ensures these woofers will play whatever you throw at them, even in the most extreme conditions.

The ring radiator tweeter, the same type you'll find in high-end home audio speakers, offers less mass than a typical dome tweeter, and its linear motion results in extremely smooth response. The tweeter's built-in wave guide helps to disperse the high frequencies more effectively. You can adjust the angle of the tweeter for best results in your listening position.

The external crossover includes 6 phase settings that optimize performance when your components aren't mounted close together. The 4-level tweeter control adjusts high-frequency output for the perfect sound for your vehicle. Enjoy in-your-face immediacy and audiophile sound quality with Alpine's Type-X Pro Series components in your vehicle.
