This is a much more expensive material which has extreme advantages over a typical Polypropylene cone for a marine environment. Polycarbonate is an excellent material due to its combination of durability, resistance to environmental factors, favorable acoustic properties. It is also a light-weight material that is strong and this means it will give the subwoofer a higher sensitivity rating which means it will play really loud even with an under-powered amplifier. These characteristics make it well-suited to withstand the harsh conditions of marine environments while providing high-quality sound performance.\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\r\n  \u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003e\u003cstrong\u003eImpressive Power:\u003cbr\u003e\u003c\/strong\u003eWith a maximum power of 1200 Watts and an RMS power of 300 Watts, this subwoofer packs a punch.\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\r\n  \u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003e\u003cstrong\u003eVoice Coil:\u003cbr\u003e\u003c\/strong\u003eThe 2.0\" 4-layer voice coils are extremely durable and high quality.
