Polk Audio's db Series subwoofers give you trademark Polk performance without stressing your wallet. These subs combine high-tech materials with a laser-optimized motor structure for smooth, powerful bass response.
The db840DVC 8" subwoofer boasts a rigid polypropylene cone and durable Santoprene™ surround built to handle big power over the long run. Polk Audio tests their subs rigorously for environmental effects caused by sun, moisture, and extreme temperature changes — they'll withstand whatever mother nature can throw at them. Polk Audio's marine certification means you can confidently take these subs out to sea and dive into some deep bass. The dual 4-ohm voice coils allow you to wire your system to draw max power from your mono amp or to safely hook up multiple subs. Match a db sub to a suitable enclosure, and enjoy impressive low-frequency performance rarely found in this price range.
