Sound-Reinforcement Loudspeakers

Panaray sound-reinforcement loudspeakers feature full-range cone transducers in proprietary array conﬁgurations that provide exceptional reliability in adverse conditions,

while delivering natural vocal clarity. For more than ﬁve decades, Bose

natural sound quality, and wide coverage patterns. Available in both point-source and column line array acoustic designs, Panaray loudspeakers cover a wide variety of

installed-sound venues, for indoor and outdoor locations.

From the legendary Bose

901

to the Professional 802

Bose ﬁrst demonstrated the advantages of

full-range cone driver arrays with the revolutionary

901 Direct/Reﬂecting

high-ﬁdelity loudspeaker.

Based on extensive research in the ﬁelds of speaker

design and psychoacoustics, the groundbreaking

speaker system won immediate acclaim for its

extraordinary ability to more closely approximate the

essence and emotional impact of a live concert.

After noting that professional musicians were using

Bose 901 speakers as PA speakers, the company

developed the Bose 800, which maximized sound

quality through use of eight 4.5-inch drivers, and formed the Bose Professional Division.

This same acoustic design was reﬁned in the Bose Panaray 802 and became one of the

world's best-selling sound-reinforcement loudspeakers.

The extraordinary Bose 4.5-inch full-range cone driver

acoustic transducers in the world, with 99.9% still operating after 5 years.

The Bose 4.5-inch full-range cone driver pioneered many innovations in transducer

design, including aluminum helical voice-coil wire to improve efﬁciency, polyester-resin

frames for more precise manufacture, and Kevlar

environmental conditions.

has been improving the performance of full-range cone transducers to provide unmatched reliability,

The key technology of the 802

loudspeaker is the full-range cone

driver. Years of research have optimized

the combination of power handling,

efﬁciency, smooth frequency response,

and wide dispersion. More than 30 years

and millions of units in production have

proven this is one of the most reliable

impregnated cones to resist outdoor

Second generation: the Bose 2.25-inch full-range cone driver

With a desire to improve the high-frequency summation in column

line arrays, Bose developed the second generation full-range cone

driver, with a 50% reduction in diameter. The 2.25-inch size provides

increased horizontal dispersion and higher frequency summation

for vertical arrays. Additionally, the smaller form factor allows denser

packing of transducers for increased output in small enclosures. The

ﬁrst Bose Professional product to utilize the 2.25-inch full-range

driver was the Panaray MA12, which launched a resurgence in the

column line array category by providing exceptional vocal clarity

in difﬁcult acoustic spaces and packaging the drivers in a slim

enclosure that visually blends with any décor.

Latest advancement: 2.25-inch cone arrays with coaxial woofers

The most recent performance advancement for Bose Professional

cone-array loudspeakers combines the advantages of 2.25-inch

cone drivers in mid/high column line arrays with coaxially mounted

woofers for increased low-frequency response and maximum

output level.
