SPX-17PRO - Alpine 6.75" Type-X Pro Series Component Speaker System

The Type-X PRO speaker embodies Alpine's no-compromise attitude to speaker performance and design. The award-winning Type-X PRO component speakers have been engineered from the ground up with the audio enthusiast in mind. They utilize advanced technologies and exotic materials often found in high-end home audio speakers to deliver dynamic sound quality with exceptional accuracy. This means you get to hear stunning musical detail, amazing lifelike sound, and incredible imaging. With Type-X PRO speakers, Alpine gives you a true sound experience in the automotive environment Hearing is Believing When engineering the award winning SPX-17PRO/SPX-13PRO, producing speakers with uncompromising sound quality was priority #1 for Alpine. Our singular focus was developing an advanced speaker system that delivers an unparalleled, dynamic musical experience. SPX-17PRO/SPX-13PRO speakers allow for extended frequency response, higher resolution, and deeper powerful bass. These drivers bring out all the detail in any type of music for an unbelievably multi-dimensional sound that totally envelops the listener. Woofer Material The extreme Type-X design starts with exotic woofer materials. SPX-17PRO/SPX-13PRO speakers use a hybrid glass fiber cone, which incorporate special pressed-in cross-ribs for increased stiffness. This sophisticated design helps break up major resonant modes and opens up the true character of the material for accurate bass response and mid-range sound clarity. The patent-pending NRSC (Non-Resonant Suspension Coupling) further enhances this by further preventing resonant modes for an unrestricted depth of sound. Rounding out the woofer design is a solid machined Billet Aluminum Phase plug that prevents phase interactions of the sound waves for more focused sound.
