About: DS18 PRO-HY6.4B 6.5" 225W RMS Coaxial Hybrid Mid-Range Loudspeaker with Built-in Driver - 4 Ohm (Each) 

DS18's PRO-HY6.4B Hybrid speakers break barriers to bring you the best of both worlds. Designed to conquer the elements, the PRO-HY6.4B is built with water-resistant paper cones to get LOUD against nature's forces! These speakers are built to withstand the harshest conditions, all while maintaining peak performance. The PRO-HY6.4B’s feature a high-volume 6.5" speaker and a 1" voice coiled driver, both rated at an astonishing 225W RMS and 450W MAX power handling. With a sensitivity of 96dB and a frequency response ranging from 100Hz to 20KHz, these speakers deliver crystal-clear sound across the entire audible spectrum. DS18's PRO-HY6.4B driver features a diaphragm crafted from titanium, renowned for its remarkable stiffness-to-weight ratio. This premium material guarantees extraordinary clarity, allowing you to hear every nuance and detail in your favorite music with pristine accuracy. The driver's magnet material is none other than neodymium, a powerful and lightweight material that ensures superior control and response. Every detail matters in the construction of the PRO-HY6.4B’s: its voice coil diameter of 1.5" and former made of glass fiber guarantee impeccable performance and durability. The cone, crafted from water-resistant paper, ensures longevity and resistance against the elements. The cloth surround, and retooled aluminum basket all contribute to an exquisite aesthetic that perfectly complements the exceptional audio quality.
Elevate your car audio system to new heights and let the PRO-HY6.4B redefine your audio expectations.
