The full-range speaker is IP65 rated, and its weatherproofing is complemented with exceptional cabinet
and grille resistance against sun, salt, moisture, and
chlorine.
u Long throw 5.25" (133 mm) woofer housed in a UL
94-5VB fire rated ABS plastic for extended LF
performance down to 55 Hz
u 90 W power handling provides for 108 dB maximum
SPL (114 dB Peak)
u 60 W transformer with 8 Ω pass-through
The LB20-PC60EW-5 includes a versatile U-Bracket
that has been designed with the installer in mind,
allowing for a wide range of installation applications.
The U-Bracket allows for 80 degrees of rotation.
The LB20-PC60EW-5 utilizes a 60 W transformer, that
offers a selection of 7.5 W (70 V only), 15 W, 30 W or
60 W delivered to the speaker system using either 70 V
or 100 V lines, or 8 Ω bypass for low impedance lines.
Selection is done with a convenient switch on the
input panel located on the rear of the speaker.
The wide range of LB20 surface mount speakers has
been designed to work together as a complete system
in a variety of different surface mount constructions,
and to be used in combination with other LB20 ceiling
and in-wall speakers.

Architectural and engineering specifications:
The loudspeaker shall be a surface mount, two-way,
full-range system, with an internal passive crossover.
The loudspeaker's low-frequency transducer shall be a
5.25" (133 mm) woofer, with a weather resistant poly
propylene cone, and a 1" (25 mm) voice-coil. The
loudspeaker's high-frequency transducer shall be a
0.75" (20 mm) Ferro fluid cooled driver, coupled to a
baffle-integrated waveguide.
The loudspeaker system shall meet the following
performance criteria: Power handling, 75 W of IEC
60268-5 continuous pink noise (6 dB crest factor);
Frequency response, 55 Hz - 20 kHz (-10 dB from rated
sensitivity); Sensitivity, 89 dB at one watt, 100 Hz - 10
kHz at one meter; Impedance, 8 Ohm nominal, 6.5
Ohm minimum.
The loudspeaker shall have a transformer suitable for
use on 70 V or 100 V distributed lines. The transformer
