Rockville 2 WET-40B 4ft Wall Speakers 70V/8 Ohm - Weatherproof Swivel

In this review the Rockville WET-40B 4' wall speakers are evaluated for small commercial zones and outdoor residential use; they are best for users who need a compact, weatherproof option with flexible mounting and simple 70V integration. The two-speaker pair focuses on durability and installation ease, with an IPX55 waterproof cabinet and a 360 degree swivel bracket that makes aiming sound straightforward. The bottom line: if you need reliable, weather-resistant wall speakers for patio, retail or hallway coverage, this pair delivers practical performance without complicated setup.

Key Features

• IPX55 Waterproof Cabinet: The waterproof ABS cabinet and aluminum grill let these speakers survive heavy rain and outdoor exposure without rusting or water damage.
• 70V or 8 Ohm Compatibility: A built-in transformer and tap switch let installers choose 70V line distribution or standard 8 ohm operation for flexible system designs.
• 360 Degree Swivel Bracket: The ball joint bracket provides full directional aiming so sound can be steered to the listening area without moving the cabinet.
• Weather-Resistant Hardware: Powder coated steel brackets pass a 96 hour salt spray test so the mountings resist corrosion in coastal or humid environments.
• Balanced Driver Set: A 4' polypropylene woofer and a 13mm PEI tweeter offer clear highs and usable low end for voice and background music applications.

Who It's For

The WET-40B pair is aimed at small business owners, restaurants, offices and homeowners who need discreet wall speakers that stand up to the elements and are simple to wire into a 70V paging or music system. Installers will appreciate the waterproof terminals and the built-in transformer for multi-zone commercial setups.

These are not designed for high-fidelity audiophiles seeking deep bass or large-room concert sound; anyone who wants very high sensitivity or extreme low frequency output should consider larger drivers or powered outdoor speakers instead.
