4″ Waterproof 2-way Passive Wall-Mount Speaker Pair, Black Liveo series combines simplicity and elegance with sturdiness and ease of installation. Whether outdoor or indoor, low-impedance or constant-voltage line, Liveo guarantees the right solution for every application. The housing, with minimalist and elegant lines, is made of Polypropylene with UV-resistant treatment; this ensures robustness and greater durability to exposure to sun, moisture and rain. Plastic woofer, Mylar tweeter and plastic cover of rear connections make these speakers completely waterproof. Both transducers are selected to offer not only waterproofness and high durability, but also an excellent level of audio quality. The buit-in line transformer allows the speaker to be adapted to both constant-voltage – with 4 selectable power levels – and low-impedance systems. Each Liveo series speaker, in order to simplify installation as much as possible, comes with both a “C” bracket and a “ball-shaped” bracket, both with adjustable horizontal and vertical positions.
