Certifications and Approvals
All plastic parts are manufactured from self-extinguishing
high-impact ABS material (according to UL 94V0).
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 operating life, and much less chance
of failure or performance deterioration.
