DS 100SE

Loudspeakers

Engineers' and Architects'

Specifications

Each loudspeaker shall be a 100-watt, ported

loudspeaker system utilizing two 2.25" (57mm)

mid-high frequency drivers mounted vertically

on a rotatable, faceted baffle and a separate

5.25" (133mm) woofer. The loudspeaker shall

be used for installation on walls and other flat,

solid surfaces.

Each loudspeaker shall have a nominal rated

impedance of 8 ohms and shall be wired

in parallel with a line voltage matching

(step-down) transformer with an accessible,

front-mounted level selector appropriate for

setting various output taps. The loudspeaker

input connections will allow for direct connection

to either 70V, 100V or low-impedance amplifiers.

Exposed cosmetic surfaces of the loudspeaker

shall be paintable, and the acoustically

transparent grille component shall be

formed of powder-coated steel.

Each loudspeaker shall have a bandwidth of

65 Hz – 16 kHz and a maximum acoustic output

of 105 dB-SPL referenced to a full bandwidth

pink noise input at 1 meter at the loudspeaker's

rated power. The input connection shall consist

of a three-position barrier connector on the

included mounting bracket. Each loudspeaker

shall be wired to the mounting bracket via

a 4-pin, pre-wired connector.

Power settings available shall be: 12.5W, 25W,

50W, 100W @ 70V; 25W, 50W, 100W @ 100V;

and 100W @ 8Ω (when referenced to IEC noise

for 100 hours). The nominal dispersion shall be

180° H x 75° V at -6 dB (average 1 – 4 kHz).

When used with optional junction boxes,

which include a pre-wired ceramic connector

and a thermal fuse, the loudspeaker shall meet

numerous standards for combination music

and evacuation systems around the world.

The loudspeakers shall be the Bose

DS 100SE loudspeakers.
