1. Full bandwidth pink noise is applied to the 302A and ampliﬁ ed to a level at the loudspeaker terminals corresponding to 1 Watt as referenced to the nominal impedance. The average

sound pressure level (dB-SPL) is measured at 1 metre from the speaker in an anechoic environment.

2. Full bandwidth pink noise is applied to the 302A and ampliﬁ ed to a level at the loudspeaker terminals corresponding to the long-term rated power handling of the speaker. The

average sound pressure level (dB-SPL) is measured at 1 metre 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 302A and ampliﬁ ed 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

302A loudspeaker is a 200-Watt loudspeaker designed

for surface-mount installations in indoor and outdoor commercial

applications. It offers the following features:

Wide-range reproduction over a broad dispersion area

A multi-tap line transformer that provides easy-to-change tap settings

for 25W, 50W, 100W and 200W (in 70V or 100V conﬁ gurations)

Transformer encased in a custom molded compartment on the speaker

bracket

Aesthetic design available in black or white to blend with decor

Mounting hardware that permits fast and easy installation

Weather resistant design and hardware to ensure reliable performance

indoors or outdoors

Installation

All hardware, the transformer, bracket, and installation instructions are

included with the loudspeakers.

The loudspeakers are designed to be mounted on a wall, ceiling, or

overhang, using the supplied U-brackets, which attach to the internal

threaded inserts. The loud speaker slips easily into the mounting bracket

and can be tilted down by 30˚ when mounted vertically or 90˚ when

mounted on a horizontal surface.

Loudspeaker conﬁ guration

The BOSE

302A loudspeaker can be used with all Bose ampliﬁ ers. It

is also compatible with industry standard professional ampliﬁ ers. The

302A loudspeaker is used as a distribu ted speaker system with its built-

in transformer. The 302A is packaged two units per carton.
