Herdio 4" Marine Box Speakers 4 Black 240 W IP66

Four-inch marine box speakers

This set supplies four 4-inch marine box speakers built for open-cockpit vehicles such as boats, UTVs, ATVs, golf carts and off-road trucks. Each unit handles 240 W maximum power, presents a 4 Ω load and covers 80 Hz–20 kHz. The IP66-rated enclosures resist heavy water splashes and spray in salt-air environments.

Swivel brackets and fixed grilles

Eight mounting screws and four adjustable brackets are included; each bracket rotates through 180° horizontally so the speakers can be aimed after the box is fastened. The grille covers are not removable, so the drivers stay protected from debris while the brackets can be detached for service or re-positioning.

Compact sealed enclosure

Each speaker measures 4.4" wide, 4.3" high and 4.2" deep (112 mm × 110 mm × 102 mm), allowing surface mounting on tight gunwales, roll cages or dash panels. The sealed box design means no separate cut-out or cavity is required, and the four-ohm impedance matches most marine amplifiers without additional wiring changes.
