Certifications and approvals
Quality assurance
All Bosch loudspeakers are designed to withstand operating at their rated power for 100 hours in accordance with IEC 268-5 Power Handling Capacity (PHC) standards. Bosch has also developed the Simulated Acoustical Feedback Exposure (SAFE) test to demonstrate that they can withstand two times
their rated power for short durations. This ensures improved reliability under extreme conditions, leading to higher customer satisfaction, longer operating life, and lessons the chance of failure or performance deterioration.

Selection is done by a convenient switch on the rear enclosure.
A two meter long twin core loudspeaker cable (in matching color with the cabinet) is connected to the loudspeaker. The core ends are stripped ready for use. The mounting brackets are fitted with anti theft torx screws, covered with plastic covers in matching color of the cabinets.
The cabinets can be mounted horizontally to allow the loudspeaker to be directed up or down, or vertically to allow left and right rotation by means of a steel U- shaped wall bracket (standard supplied).
The rotatable logo can be easily adjusted to match the mounting orientation.
