HP4S BK Boat 3-Pack

Outfit your boat, patio, or indoor lounge with a six-speaker set designed for clear sound and confident placement. The Rockville HP4S 4" box speakers pair weather-resistant construction with a compact footprint that mounts cleanly on walls, rails, and hard surfaces. Swivel brackets let you aim audio across a deck, toward seating, or down a dock walkway for balanced coverage. With IPX44 water resistance and rust-resistant grilles, they’re suited to mist, rain, and humid environments. The result is bright detail, punchy midrange, and a tidy, modern black finish that complements today’s marine and outdoor aesthetics.
