Polk DB+ Series Coaxial Speaker

The Polk Audio DB462 DB+ Series coaxial speaker offers marine-certified audio performance for demanding environments. With dimensions of 10.2 x 15.2 cm (4 x 6 inches), this black speaker combines a tweeter and woofer in a coaxial design for coherent sound reproduction. The marine certification indicates resistance to saltwater corrosion, UV radiation, and moisture, making it suitable for marine applications, outdoor installations, or humid environments. Made from durable materials, the DB462 features a polymer basket and rubber surround for long-term reliability. The coaxial configuration provides improved sound imaging compared to separate component designs. This speaker works with standard car audio or marine amplifier systems and has a power handling that corresponds to its size class. Installation requires standard mounting procedures with the included hardware. The black finish offers visual discretion in various settings. Polk Audio's DB+ Series represents the successor to earlier DB designs, with refinements in materials and construction. For optimal performance, compatibility with the enclosure and amplifier matching should be checked. The product is delivered without additional accessories other than mounting hardware. Technical specifications include impedance values and frequency response characteristics typical for this category. Despite the marine certification, users should consult manufacturer guidelines for specific installation requirements and environmental constraints.
