The Pyle Hydra Series is a pair of 3.5″, 200 watt, heavy-duty mini box weatherproof speakers-ideal for the deck, the backyard, by the pool or on your boat or other marine vehicle. They’re completely waterproof, featuring a rustproof grilel that’s removable for cleaning. These 3 way speakers provide the full spectrum of sound, thanks a 3.5″ aluminum injection cone woofer with a 24 oz. magnet for the low end, a 1.75″ wide dispersion cone for the midrange, and a 1″ super dome tweeter for the highs.
