📝 Reviews

💬 “Sound is very balanced with decent mid-bass… These speakers are very inefficient (83 dB) needing a lot of power.” — Crutchfield customer

💬 “Compact outdoor loudspeaker with long-throw 3.5″ woofer and 3/4″ dome tweeter; waterproof housing.” — Amazon product page

💬 “A versatile outdoor speaker… stake-mounted with included hardware; loud, clear music exactly where you want it.” — Crutchfield editorial
