Rockville RWB90B 8ft 2-Way Marine Wakeboard Tower Speakers - Clear

In this review the Rockville RWB90B pair is evaluated as a purpose-built set of marine and off-road speakers for users who need loud, clear sound in open-air environments. These 8' 2-way speakers promise 200W RMS (300W peak) and a 1' polymide dome neodymium tweeter for detailed highs, and the biggest reason to buy is the combination of marine-grade durability and adjustable 360-degree swivel mounting that lets you aim sound precisely from a wakeboard tower, roll bar, or roll cage.

Key Features

• High-fidelity audio: The 8' polypropylene mica cone and 1' polymide dome tweeter deliver balanced midrange and crisp highs that cut through wind and water spray for better open-air listening.
• Marine-grade construction: Fully marinized components, rustproof stainless steel terminals, and UV-coated nylon brackets resist salt and freshwater exposure for long-term outdoor use.
• 360-degree swivel mount: Adjustable brackets with embedded steel fit 1.26 in to 2.87 in bars so the speakers can be positioned and aimed for optimal coverage on boats, Jeeps, or ATVs.
• Easy installation: The package includes stainless hardware, 65mm and 80mm screws, and integrated grills to simplify mounting on wakeboard towers and roll bars with minimal extra parts.
• Advanced crossover design: Built-in crossover and santoprene surround provide controlled excursion and focused PA-style voice-over clarity in open-air scenarios.

Who It's For

The RWB90B is ideal for boat owners, wakeboarders, and off-road enthusiasts who need weatherproof speakers that can be aimed to cover passengers or an activity area. Installers who value straightforward hardware and compatibility with common tower and roll bar diameters will appreciate the included stainless screws and swivel brackets.

Those who want studio-level indoor fidelity or very shallow-mount in-dash solutions should look elsewhere; these speakers are tuned for outdoor SPL and durability rather than tight, room-refined bass or compact dash integration.

Pros & Cons

Pros

• Robust, marine-grade parts and UV-resistant brackets for reliable outdoor use.
• Strong, clear mid and high output from the 1' neodymium tweeter and polypropylene mica cone.
• Versatile 360-degree swivel mounts that fit a wide range of tower and roll bar sizes.

Cons

• Build and swivel function received mixed feedback from some users, so expect occasional variability in long-term durability.
