Amazon.com Product Description
Built to withstand the toughest marine environments--including always-wet ski and wakeboarding boats--Polk Audio's DB 804 DVC subwoofer offers topnotch low-frequency performance and durability at a wallet-pleasing price. The sub is outfitted with an 8-inch "dish" polypropylene cone woofer that delivers enough rim-rattling bass to make any song sound rich and deep. The woofer is further supported by a vented cone/coil coupler that stiffens the cone, thus ensuring greater mechanical stability and lower distortion. Add in the dual, four-layer Kapton voice coils and the pole piece--both of which are triple vented to withstand high power handling--and you have a powerful, full-bodied sub that satisfies everyone from casual listeners to serious audiophiles. The sub's frequency response checks it at a healthy 30 Hz to 200 Hz, with a peak power handling of 360 watts (180 watts continuous). In addition, the DB 804 DVC's voice coil alignment, motor, and suspension were optimized using a state-of-the-art Klippel laser analyzer, resulting in superior cone linearity, a flatter response, and minimal distortion. Additional features include a Santoprene surround that stands up to the harshest automotive environments--including temperature, humidity, and sunlight extremes--and fire-retardant flat Nomex spiders that are thermally stable while providing extended linear motion. Though the marine certification makes the sub a particularly good choice for seafaring listeners, it also fits comfortably in cars, trucks, and other vehicles. The DB 804 DVC requires a mounting cutout diameter of 7.06 inches and is backed by a three-year warranty on parts and labor. What's in the Box
