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

u Compact yet robust ABS enclosure

u Supplied with adjustable mounting bracket

u Water and dust protected IP65

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 U­shaped wall bracket (standard supplied).
The rotatable logo can be easily adjusted to match the
mounting orientation.
