The Polk Audio DB692 DB+ Series 6" x 9" Coaxial Speaker is a versatile option suitable for both car and marine environments. Its key strength lies in its waterproof rating with IP56 marine certification, making it resistant to water, UV rays, salt-fog, and humidity, which is perfect for use in boats and other outdoor vehicles.

With a peak power handling of 450W and RMS of 150W, this speaker can deliver powerful sound, and its 30-22kHz frequency response ensures a wide range of audio playback from deep bass to high treble. The inclusion of a 1/2" silk dome tweeter and a polypropylene woofer cone enhances sound quality and durability. Additionally, the Dynamic Balance technology helps reduce distortion and ensures a clear sound output.

The ease of installation, with supplied mounting hardware and stylish grilles, makes it a user-friendly choice for custom setups. However, users should note that while the speaker is waterproof, it requires a corded electric power source, which may not be as convenient as a wireless option. Additionally, its size and weight (around 7 pounds) might be a consideration for those with limited installation space. Despite these minor drawbacks, the Polk Audio DB692 offers a robust and high-quality audio solution for both car and marine use.
