Polk Audio DB692 6x9 Marine 3-Way Coaxial Speaker | Car & Boat

Overview

The Polk Audio DB692 6" x 9" 3-Way coaxial speaker is engineered to perform in both car and marine environments. It blends a polypropylene woofer cone with a 3/4" silk dome tweeter and a 1/2" super tweeter, all driven through a built-in crossover to deliver smooth, precise sound across a broad range. With 450W peak power and 4-ohm impedance, it’s designed to elevate everyday listening without demanding extra gear.

Dynamic Balance technology uses laser imaging to optimize material pairing and minimize resonance. The result is a cleaner, distortion‑free response with wide dispersion, so music sounds balanced from different seating positions. The 30 Hz to 22 kHz frequency range helps you hear both the low fundamentals and the subtle high harmonics, whether you’re cruising along or parked in a marina lot.

Durability is built in. The DB692 belongs to Polk’s DB+ family, featuring a coated steel basket and splash‑proof construction that’s tested for salt fog, UV exposure, and humidity. These tests mimic conditions you might encounter on water or in high‑sun, high‑humidity environments, helping ensure reliable performance over time.
