👎 Cons

The 700W power handling is likely a peak or max power rating, not continuous RMS, which is a more realistic measure of sustained performance.
Specific details on frequency response, impedance, or sensitivity are not provided, making it difficult to assess overall sound fidelity.
The 6.5-inch size, while common, might not provide the deepest bass response without additional subwoofers.
While water-resistant, a specific IPX rating for waterproofing is not mentioned, which could be important for harsh marine conditions.
The product does not mention any included grilles or mounting hardware beyond the speakers themselves, which may be needed for installation.
The "anti-resonant stamped basket" is a design feature, but the material (e.g., plastic, metal) is not specified.
The white color may show dirt or scuffs more readily than darker speaker finishes.
