Ceiling Speaker for public address systems
BS-30 | BS-120

Two-way public address system for speech and music transmission of exceptionally good quality for installation in ceilings or for ceiling suspension or similar ceiling constructions. 4 two-way chassis with an excellent degree of effi-
ciency and extraordinary sound characteristics. In addition, it is supported by a high-range horn. Housing consists of varnished medium density fibreboard with mounting lugs for suspension via steel cables.
Whereas conventional ceiling speakers are characterized by a hemispherical sound radiation below 1 KHz, we optimized the radiation characteristics thanks to 4 chassis, so that a defined focussing dimension can still be achieved
even in the critical mid-range zone.
Due to its balanced radiation characteristics, high efficiency and maximum level this speaker is strictly in line with the particular requirements of environments with long-lasting resonation, high ceilings and high interference noise level.
