All loudspeakers of Bosch meet the IEC 268-5 maximum output power (PHC) standard and can work for 100 hours at rated power. In addition, Bosch has developed analog acoustic feedback exposure (SAFE) tests to demonstrate that its loudspeakers can operate at twice the rated power in a short time. At the same time, it also provides additional reliability for loudspeakers to work under harsh conditions, which not only improves customer satisfaction, prolongs service life, but also reduces the probability of failure or performance degradation.
