The Power T4 6.5” component system mimics the performance of our flagship model but includes a crossover that’s effortless to install. The LCP (Liquid Crystal Polymer) dome tweeter features a phase plug that guides high frequency waves toward the listener for an extended frequency response. The woofer features a woven LCP fiber for optimum frequency response. These combined with an asymmetrical 12dB Butterworth crossover offers audiophile sound quality in an efficient 2-way system.FEATURES AT A GLANCE 1" (25mm) ring radiator LCP dome tweeter w/ aluminum phase plug LCP (Liquid Crystal Polymer) fiber sandwich woofer cone Die cast aluminum frame FlexFit slot woofer mounting Fatigue and tear resistant linear Nomex spider VAST (Vertical Attach Surround Technique) Butyl rubber surround DDC (Discreet Dual Clamp) tweeter mounting system Grilles and mounting hardware included Selectable +2, 0, -2 dB tweeter level settings Selectable bi-amp switching Asymetrical 12dB/Oct Butterworth crossover network Flush and surface (angled) tweeter mounting hardware included 1 Year Warranty Multi-pole™ neodymium motor structure Sold in pairs (2 each) Selectable on/off axis setting
