The BS-1030B is a small, 2-way bass-reflex type speaker featuring a wide frequency range suitable for use for announcements and music playback. The BS-1030B can be used for both high-impedance and low-impedance applications. The speaker's smoothly curved surface permits it to blend in with virtually all modern buildings. A built-in matching transformer permits the speaker to be used for both high-impedance and low-impedance (8 Ω) applications. The impedance can be easily changed from outside the speaker. A splash-proof design enables the BS-1030 to even be installed outdoors in a location not directly exposed to the elements such as under eaves. Mountable to wall surfaces directly or using with supplied or optional mounting brackets. Features Type: Wall Single/ Pair: Single Wall mountable: Yes
