Functions
The LBC3951/12 has a perforated metal grille with a
plastic surround, finished in an attractive off-white
RAL color. The unobtrusive styling of this loudspeaker
complements today’s interior lighting.
The loudspeaker features a very wide opening angle,
which means fewer units are required to cover a given
area. The wide frequency range means better speech
and music reproduction. The unit is supplied with a
100 V matching transformer with taps on the primary
winding for full-power, half-power, quarter-power and
eighth-power radiation.
The loudspeaker (with special treated paper cone) is
IPx4 water protected from the front and can be
applied in humid environments, for example in
bathrooms, saunas, atriums and swimming pool areas.
