It's time for a pair of high-quality outdoor speakers like the Atrium 45 from Polk Audio. The speakers each feature all-stainless-steel and brass hardware for years of rustproof reliability and a rustproof aluminum bracket that permits multiple mounting options and full 90 degree rotation: you can aim them to deliver the best possible sound in a variety of positions. The Atrium 45 speakers have a wide dispersion pattern, and they're very efficient, operating on as little as 10 watts per channel. They're designed to deliver good sound quality across a large listening area, but Polk recommends multiple-pair setups if you want high sound levels in an outdoor setting, as sound tends to dissipate more quickly outdoors than in.
