Masteronly 3.5" Outdoor Speakers | 200W Waterproof Wall Mount Speaker Pair for Patio, Pool & Boat

Transform Any Outdoor Space Into a Premium Sound Experience

Whether it's a sunset dinner on the patio, a pool party, or a day out on the boat — the Herdio HOS-301 delivers rich, powerful audio that stands up to the elements. Built tough. Sounds incredible.

🔊 SUPERIOR SOUND QUALITY

Engineered with a 3.5" aluminum injection cone woofer and a 1.0" dome tweeter, the HOS-301 delivers a wide, balanced soundstage across 80Hz–20kHz. With 200W peak power (pair) and 100W RMS, every note — from deep bass to crisp highs — comes through with stunning clarity. Note: These are passive speakers and require a separate amplifier or receiver.

💧 WATERPROOF & BUILT FOR THE OUTDOORS

Rain, humidity, splashing — no problem. The marine-grade ABS enclosure is fully weatherproof with a water-resistant painted finish and a rust-proof removable grille. Designed to perform season after season, wherever you install them.

🔧 EASY INSTALL WITH 180° SWIVEL BRACKETS

Aim your sound exactly where you want it. The included 180° swivel mounting brackets feature a quick-lock system and anti-slip design, making installation fast and secure — on walls, ceilings, pergolas, or boat decks.
