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 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.
