u Suitable for speech and music reproduction
u Extreme compact size
u Suitable for use in humidity-, chlorine- and salty
environments
The LC5‑WC06E4 is an extreme compact ceiling
loudspeaker, suitable for speech and background
music reproduction. The design of the front grille
perfectly matches with current available recessed
luminaires, integrating light and sound.
The optional back‑box LC5‑CBB fully protects the rear
of the loudspeaker from dust and dripping water from
above, making the combination IP 44 protected.
The loudspeaker frame, grille and back‑box are
manufactured from self‑extinguishing ABS according to
UL 94 V 0.
This ceiling loudspeaker is suitable for use in low
ceiling applications with low noise level. The small
driver used in the unit stands for delivering good
sound quality from a small sized unit and provides a
wide opening angle for the important frequency
octaves. Fewer loudspeakers are needed to cover a
given area, and the noticeable “fading” that occur as a
listener walks from one loudspeaker to another area is
eliminated.
The loudspeaker (with assembled back‑box) is suitable
for use in humidity-, chlorine- and salty environments.
u Selectable 70 V ,100 V and 8 Ohm input
u EN 54‑24 certified

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
improved reliability under extreme conditions, leading
to higher customer satisfaction, longer operating life,
and lessons the chance of failure or performance
deterioration.

Installation/configuration notes
Installation is easy with two integral leaf springs that
securely hold the loudspeaker in its cut‑out. The
integral leaf springs can be adjusted in three positions
to accommodate ceiling thicknesses from 5 mm to
25 mm. The size of the ceiling cut‑out opening is
standardized on available 3” (76.2 mm) cutting hole
saws.
No tool required for fitting the loudspeaker into the
ceiling cut‑out.
The loudspeaker has built‑in protection to ensure that,
in the event of a fire, damage to the loudspeaker does
not result in failure of the circuit to which it is
connected. In this way, system integrity is maintained;
ensuring loudspeakers in other areas can still be used
to inform people of the situation.
The loudspeaker has ceramic screw‑terminal
connection blocks, thermal fuse and heat-resistant
high temperature wiring.
Connections are made using two 2‑way screw terminal
blocks at the rear of the loudspeaker, where each
incoming and outgoing conductor of the same
potential can be connected to a separate terminal.
Power tapping on both 70 V and 100 V allows
selection of full‑power, half‑power, quarter‑power and
eight‑power radiation, and 8 Ohm.
The optional back‑box (LC5‑CBB) protects the rear of
the loudspeaker from water and dust, falling objects,
makes the unit vermin proof and prevents sound
traveling via the ceiling cavity to adjacent areas. The
back‑box is assembled with the loudspeaker by means
of a snap‑in construction and has on top two
knock‑out holes for two rubber cable grommets
(11 mm/0.43”), standard supplied.
