The \"Faraday Ring\" integrated into the voice coil increases power handling and reduces potential distortion, thus providing clean bass even at higher volumes than before. The cones of the R-Series subwoofers are Kevlar-reinforced, making the cone extremely durable without excessive weight increase.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eTop-tier performance, already in its second generation\u003c\/h3\u003e\n\u003cp\u003eBefore the R-Series, Alpine had the Type-R series, which became known for its performance, reliability, and truly tight bass reproduction.
