The Champion Series subwoofers have evolved from Pioneer’s award-winning “SPL Champion Edition” lineup, known for their deep and powerful bass production. The TS-A301D4 12 in. dual-voice coil component subwoofer features a large and powerful motor assembly for improved efficiency and sensitivity. The subwoofer baskets are optimized using a reinforced structure design for added strength and reduced vibration to deliver excellent sound quality. This 12 in. subwoofer has a continuous power of 500 watts with a maximum peak of 1,600 watts. It features an advanced 2-piece cone designed with a highly rigid and durable Honeycomb IMPP composite cone structure plus a rigid drive cone to deliver high output levels with reduced distortion. This speaker should be placed in an enclosure for best performance (enclosure not included).
