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 extra
reliability under extreme conditions, leading to higher
customer satisfaction, longer operation life, and much less
chance of failure or performance deterioration.
