Outdoor weatherproof speakers are made of rugged material that won't fade in sunlight due to UV resistant qualities. The casing enhances the natural sounds from the high-quality speakers by suppressing any unnecessary resonance. The speakers produce great sound quality at almost any volume level no matter how cold, icy, wet, hot, dry, or muggy the weather is outside. They also excel outdoors due to their a rust-proof aluminum grille. They can sit outside and stand up to the elements, including the sun, water, and wind. And they sound great, too, with detailed, clean highs and powerful lows.
