The RH-AUDIO bgm speaker with slim column shape is made out of the wooden enclosure and fabric grille, employing full rang 4inch speaker driver which produce good clear sound and acoustical clarity.
Made with built-in transformers which suit both 70V and 100V high-voltage audio distribution systems, the line voltage system can have their speakers daisy chained in parallel together without worry. Because the 70v or 100v speakers come with transformers, impedance is not an issue unless an excessive amount of speakers are going to be installed together. It is recommended to use multiple wire runs back to the bgm amplifier as opposed to a single run. This will reduce location problems that occur and make it easier to find by isolating it on individual small speaker runs.
Fitted with a length of connecting cable, finished in grey color, easy and secure wall mount through the mounting hook. And this column speaker has the character of line array so it can provide high sound pressure as 3 dB that is half ofthe amount of decreasing sound pressure compared with one unit speaker. In case of cell speaker, the space that can be influenced by direct sound pressure is small due to the pattern of vertical but the column speaker can cover the large location such as lobby, exhibition, amusement park ,stations and so on because it is possible to send output far away.
