| New Bosch Ceiling Mounted Loudspeaker
By Branko Miletic | Wednesday | 19/03/2008
Bosch Security Systems? new ceiling-mounted loudspeaker system combines high speech intelligibility with good music reproducibility. The system?s innovative hemi-directional design generates sufficient sound pressure to cover around 600 sq meters (depending upon mounting height), making it very well suited for large venues with high ceilings.
Omni-directional public address loudspeakers offer many advantages, such as broad coverage and little installation effort. A drawback of current designs, however, is inconsistent sound reproduction over the coverage area, with flat spots in the high-frequency response. Bosch has addressed this drawback in its new hemi-directional PA loudspeaker with an innovative acoustic design. Using 14 specially positioned speaker drivers combined with advanced filtering, the design eliminates flat spots in the frequency response. The result is consistent, high-quality sound reproduction over the whole coverage area. The advanced design also results in a broad frequency response over the audio range from around 60 Hz to over 17 kHz, resulting in extremely high-quality music reproduction.
