The inclusion of white grilles adds a sleek look to match most boat interiors.

Additionally, these speakers offer a frequency response of up to 21,000 Hz and a maximum output power of 65 watts, providing a robust and clear sound performance. The coaxial connectivity and 4-ohm impedance further enhance their audio delivery. Constructed from polypropylene, they are built to withstand UV exposure, which is an essential feature for marine environments.

However, it's worth noting that these speakers do not come with a retail box or additional accessories, as they are shipped in plain brown packaging. This might be a drawback for those looking for a more complete package. Furthermore, while the speakers are marketed with voice control capability, this feature may not be critical for all users. In terms of mounting, they are designed to be boat-mounted, ensuring a secure and straightforward installation.

The sealed motor structure and locking terminal covers further protect the internal components from water and dust.

With a power handling of up to 390 watts, these speakers can produce loud and clear audio, making them suitable for various marine activities.

However, the 21 KHz frequency response might be a bit high for some users looking for deeper bass. Mounting options are fairly straightforward, making installation easier even for those who aren't very handy.

One potential downside is that these speakers are corded electric, which might limit placement options depending on your boat's setup. They are relatively lightweight at 6 pounds, which should make them easy to handle during installation.

They feature a polypropylene woofer cone and a 1/2" silk dome tweeter, providing a good balance of durability and sound quality.

The speakers have a peak power handling of 450 watts and an RMS of 150 watts, which makes them robust enough for high-volume use without distortion, thanks to the Dynamic Balance technology that minimizes resonance and ensures clear sound dispersion.

The installation process is straightforward due to the included mounting hardware and stylish grilles, adding to the convenience.

Despite these strengths, it’s worth noting that the speakers are fairly heavy at 7 pounds, which might require secure mounting in some installations. Additionally, while they are designed to be splash-proof, they might not withstand submersion, making them less suitable for extreme marine conditions. The Polk Audio DB692 is an excellent choice for users seeking reliable, high-quality sound in both land and marine settings.
