The \"Faraday Ring\" integrated into the voice coil increases power handling and reduces potential distortion, which in turn provides clean bass reproduction even at higher volumes than before. The cones of the R2-Series subwoofers are Kevlar-reinforced, making the cone extremely durable without excessive weight gain.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eTop-tier performance, now 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 very tight bass reproduction.
