These white Pyle indoor/outdoor waterproof speakers are excellent for use on boats, decks, patios, or by the pool - anywhere outdoors. And they're compatible with 70 V PA systems - this model includes built-in transformer tappable at 3.75, 7.5, and 15 watts. They're completely waterproof, thanks to the rugged plastic enclosure. And they're powerful - 200 watts max. A 3.5' long throw woofer with 30 oz. magnet provides the midbass, while a ½' polyamide dome tweeter pushes sweet highs. These speakers deliver a frequency response of 100 Hz to 20 kHz. Mount using the included spring loaded U-mounting brackets. Sold as a pair.
