User manual BOSTON ACOUSTICS VOYAGER 4

[. . . ] All models in the Voyager line are true two-way designs with all acoustic parts sealed and gasketed against penetrating weather. Drawing from over a decade of all-weather speaker expertise, Boston built the Voyager series to minimize exposure of acoustic parts to weather and with materials proven to resist the elements: polypropylene cabinets with UV light and impact resistance, all-aluminum grilles and brackets, gold-plated speaker connectors. [. . . ] It is important that your speakers are hooked up with similar polarity or "in phase. " A simple listening test will tell you if your speakers are connected properly. While listening to music with your amplifier set to MONO, reverse the connections at one speaker only. The listed power recommendations assume you will operate your system in a way that will not produce distortion. Even these rugged speakers can be damaged by a modest amplifier if it produces distortion. Prolonged or repeated operation of your speaker with a distorted signal from the amplifier can cause damage that is not covered by the warranty. Taking a few minutes to place your speakers correctly ensures that your speakers will sound best in any indoor or outdoor environment. Typically, placement near a wall or other surface will increase the bass output of the speaker. Outdoors, placement under the eaves of a roof reduces exposure to constant direct sunlight and precipitation, which will extend the speaker's life. Placement under the eaves or on a wall near the ground will increase bass. In situations where you need to avoid disturbing neighbors, you may wish to install the speakers on a post or railing facing the house and listening area (the sound area will be more contained). Before running permanent wires and mounting the speaker, you may wish to test the speaker placement first for coverage and good stereo sound. [. . . ] When the speakers are installed in hard-to-reach locations, you may brush them with a soft broom. Avoid directing a garden hose at the speaker--it can damage the drivers or dislodge the wiring. [. . . ]
