399-8B/16B GENERAL PRODUCT DESCRIPTION
Altec Lansing's 399-8B and 399-16B compact, high frequency,
compression drivers have been designed for use in high level sound
reinforcement systems where both wide bandwidth and substantial
acoustic output level are essential. When used with Altec Lansing
Mantaray
TM
high frequency horns, the energy produced by these drivers
can be directed to cover an audience accurately and completely. Their
wide range response, when complemented by Altec Lansing low
frequency loudspeaker systems, will provide smooth reproduction of
speech and music for installations in auditoriums, churches, stadiums, and
arenas.
The robust Pascalite diaphragm extends the driver's power handling
capability, while maintaining superior high frequency bandwidth. The
compact magnetic motor-structure, utilizing a 6.7 lbs. (3.0 kg) ferrite
magnet, provides a 2.05 T gap flux density. An exclusive Tangerine
radial phasing-plug assures a smooth upper range response.
The excellent performance characteristics of these drivers make them the
high frequency component of choice for all large sound systems when
premium dynamic reproduction is required.
MR II 564B/594B GENERAL PRODUCT DESCRIPTION
Altec Lansing's MR II 564B and MR II 594B Mantaray
horns feature efficient mid and high frequency response with proper
loading down to 500 Hz, plus excellent directivity control over their
respective 60°Horizontal x 40°Vertical and 90°Horizontal x 40°Vertical
coverage patterns.
The geometry of the MR II 564B and MR II 594B reduces the problem of
high frequency beaming and maintains uniform dispersion at all
frequencies within the rated frequency range. Therefore, the same
quality sound will be heard by listeners sitting off-axis and on-axis to the
MANTARAY
TM
horn.
Altec Lansing MANTARAY
TM
horns are constructed of heavy-duty, weather
resistant fiberglass. This construction technique results in a horn design
that is surprisingly lightweight, yet extremely rugged and non-resonant.
