All Bosch loudspeakers are certified to meet IEC 268-5 power amplifier (PHC) standards and can operate continuously for 100 hours at rated power. Bosch has also conducted simulated acoustic feedback exposure tests to ensure they can withstand twice the rated power in a short period of time. This ensures higher reliability in extreme conditions, improves customer satisfaction, extends service life, and significantly reduces the chance of failure or performance degradation. Safety in accordance with EN 60065 emergency BS 5839-8/EN 60849 regional certification Europe CE
