User manual BOSTON ACOUSTICS RK5

[. . . ] But outdoor listening is usually part of more active forms of recreation. So considerations such as stereo imaging or proper surround sound are not the main concern. For outdoor speakers most often the main goal is to provide good sound coverage over the area where you enjoy your outdoor activities. [. . . ] There are two main listening areas ­ around the table on the patio (a) and the lounge chairs (b) out in the yard. Two speakers are placed against the walls of the house, facing in toward the patio. This provides good coverage to the area where the table and chairs are. Another pair of speakers are placed against the fence facing the lounge chairs to provide sound coverage for that area. In these examples the RK5, being a monoonly speaker, would have normal stereo separation. the RK6T2 and RK8T2 could be wired for mono to produce normal stereo separation. Or they can be wired so both channels are reproduced by each speaker, sacrificing stereo imaging for more even sound distribution of both channels. After the speaker locations have been chosen, you must run wires from the speakers to the amplifier that drives them. If the wire must be run more than 75 feet or if more than speaker channels are used, a high voltage distribution system is recommended. Such systems use a special amplifier that has a "70V" (or in some countries, "100V") output. This allows the relatively small gauge speaker wires to be run over great distances without signal degradation. The RK series speakers have provisions for mounting the transformer inside a cover located on the bottom of the speaker where the wires emerge. It is important that all the speakers in a system are hooked up with similar polarity or "in phase. " The speaker terminals on amplifiers are color coded and marked for polarity ­ typically red is + and black is ­. The RK series models have "pig tail" wire leads that extend from the bottom of the cabinet. The wires are color coded in the usual way ­ red is + and black is ­. [. . . ] 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.
