Pair Rockville RMSTS65B 6.5in 800w Waterproof Marine Boat Speakers

In this review the Pair Rockville RMSTS65B 6.5in marine speakers are evaluated for boat and outdoor use; they are best for buyers who need a rugged, waterproof pair that can handle an external amplifier and deliver loud output. The main reason to consider them is their marinized construction and CEA compliant power rating of 100 watts RMS per speaker (400 watts peak), which promises a higher power ceiling than budget marine speakers. This set comes with speaker wire and mounting screws so installation is straightforward for a DIYer.

Key Features

• Fully waterproof: The speakers are completely marinized against salt and fresh water to protect components during regular boat use.
• Power handling: With 100 watts RMS per speaker and 400 watts peak, they offer headroom for louder playback when paired with an amplifier.
• Durable hardware: Stainless steel terminals and a molded ABS basket reduce corrosion risk in marine environments.
• Tweeter and voice coil: A 1in titanium tweeter and oversized CCAW Kapton voice coil improve high-frequency clarity and thermal durability under load.
• Included accessories: The pair ships with 16.4 ft of speaker wire and mounting screws so you can mount them immediately without hunting for parts.
• Weather-treated cone: The polypropylene mica-injected cone and rubber surround resist UV and moisture for longer life outdoors.

Who It's For

The RMSTS65B pair is aimed at boat owners, marine audio DIYers, and outdoor enthusiasts who need a weatherproof speaker that can tolerate exposure to sun, spray, and occasional immersion. It is also appropriate for car owners who want a durable 6.5in two-way speaker set that can benefit from an external amplifier.

These are not the best choice for audiophiles seeking pristine, studio-level fidelity or for anyone expecting faultless reliability without proper system matching; some buyers report mixed sound impressions and a few instances of short-term failures, so buyers who need long-term, worry-free reliability for commercial installations should consider higher-end marine models.

Pros & Cons

• Higher power handling (100W RMS per speaker) makes them suitable with an external amp.

• Clear, bright highs from the 1in titanium tweeter when paired appropriately.

Cons

• Sound quality receives mixed feedback from customers, so tonal performance may vary by system and source material.
• Several customers reported units failing after limited use, indicating potential reliability issues in some cases.
