Full bandwidth pink noise is applied to the 402-II speaker and amplified to a level at the loud-
speaker terminals corresponding to 1 watt as referenced to the nominal impedance. The average
sound pressure level (dB-SPL) is measured at 1 meter from the speaker in an anechoic environment.
2
Full bandwidth pink noise is applied to the 402-II speaker and amplified to a level at the loud-
speaker terminals corresponding to the long-term rated power handling of the speaker. The average
sound pressure level (dB-SPL) is measured at 1 meter from the speaker in an anechoic environment.
3
Full bandwidth pink noise, meeting International Electrotechnical Commission (IEC) Standard
#268-5, with a spectrum corresponding to average program material.
4
Full bandwidth noise, meeting the IEC Standard #268-5 is applied to the 402-II speaker and
amplified to a level at the loudspeaker terminals corresponding to the power handling of the
loudspeaker. The loudspeaker must show no visible damage or measurable loss of performance
after 100 hours of continuous testing.

General Description
The Bose 402 Series II loudspeaker
®
is a 120-watt speaker designed for
permanent installations and portable
use indoors and outdoors. As a new
addition to the Bose line of Installed
AnyWhere loudspeakers, it meets
TM
our strict standards for outdoor use.
The 402 Series II loudspeaker offers
the following features:
• Voice and music reproduction over
a broad dispersion area
• A rugged, portable enclosure with
metal grille
• Slim, aesthetic styling in black or
white
• Weather-resistant design to ensure
reliable performance indoors and
outdoors
• A full complement of brackets and
stands available for a variety of
product uses
Each 402 Series II loudspeaker uses
four (4) 11.34 cm full-range drivers
mounted in symmetric vertical pairs
on a faceted Articulated Array
loudspeaker baffle assembly. The
drivers feature low-impedance, edge-
wound Ferrite V ceramic magnets,
and molded polyester frames. Their
advanced cone and motor system
gives them high linear excursion
capability and power output. Environ-
mental durability is built into soft
parts – cone, surround and spider –
and coated onto the hard parts of the
driver. These materials optimize the
weather resistance of the loud-
speaker when it is installed outdoors.
402 Series II loudspeakers are used
in combination with the PANARAY
system digital controller or the Bose
1600 or 1800 amplifiers. The amplifi-
ers work in combination with the 402
plug-in EQ card to provide active
equalization for the system.
The PANARAY system digital control-
ler assures smooth, accurate spectral
