GENERAL PRODUCT DESCRIPTION
Altec Lansing’s new DE6412-8A two-way 12” Duplex
®
point-source speaker
system is designed to provide a high output solution for reverberant spaces.
The DE6412-8A is an excellent choice for Auditoriums, Performing Arts
Centers, Houses of Worship or any application requiring high output
reproduction of both music and speech program material.
The DE6412-8A features Altec’s unique 12” Duplex
®
point-source speaker
component. This Duplex
®
“Engine” uses a single magnet structure, with
the high frequency diaphragm on the back of the magnet and the low
frequency voice coil and cone on the front of the structure. The result of
the proximity of the voice coils is a point-source alignment. Altec Lansing’s
use of this point-source Duplex
®
, or coaxial, design maximizes speech
intelligibility by minimizing the interference from adjacent devices that so
often occurs in traditional two-way speaker systems.
The 12” Duplex
®
“Engine” is installed in a bass horn cabinet. This trapezoid
enclosure provides predictable control in both the horizontal and vertical
planes to below 500Hz (see polar charts, page 3). The use of a bass horn
cabinet insures that much of the low frequency energy is kept off the
performance area, even when the speakers are flown overhead.
The DE6412-8A “Engine” is built around Altec’s large format 1.4” exit
throat high frequency compression driver, using a 2.8” Pascalite™
aluminum alloy diaphragm. The high frequency energy is fed from the
driver through the center of the magnet structure into a 60˚ x 40˚
Mantaray
®
high frequency horn. On the front of the magnet structure,
Altec uses a high efficiency 12”/300mm cone woofer optimized for bass
horn enclosures.
The paintable trapezoid cabinet is constructed from strong 13-ply birch
plywood, with steel reinforced suspension points. Altec includes the
suspension hardware kit with each speaker. Color choices are charcoal gray
or white, with contrasting cloth covered metal grille. The DE6412-8A has
an internal 1,200Hz passive network that can be easily switched over to
bi-amp operation. Connectors are barrier strip or Neutrik
®
Speakon
®
connectors. Altec Lansing includes neutral grille cloth with each subwoofer,
allowing you to dye the cloth to integrate the subwoofer into the
surroundings.
For extended low frequency performance, the LF215-4A is a dual
15”/380mm flyable subwoofer that has the same trapezoid footprint as the
DE6412-8A. Altec Lansing’s model 4048A 4-in x 8-out DSP processor has
available presets for a variety of design requirements.

SPECIFICATION NOTES
1 The frequency response of the loudspeaker system is measured at a distance of no less than 3 meters to obtain full range data. The level is
then corrected to be equivalent to a 2.83 V 1 m measurement. A near field measurement of the loudspeaker system is performed for
frequencies below 500 Hz. This data is then combined with the full range measurement to give an accurate composite frequency response
curve.
2 The limits of the frequency response are referenced to -3 dB of the systems rated sensitivity.
3 The sensitivity of the loudspeaker system is the log based average SPL taken over the intended bandwidth of operation for the system with a
2.83 V swept sine stimulus. The data is measured and level corrected in a manner consistent with note 1.
4 The power handling capacity of the loudspeaker system is tested using a full range form of AES Standard 2-1984. The test stimulus is band
limited (40 Hz – 16 kHz) pink noise with a 6 dB crest factor. The applied RMS voltage is determined using the minimum impedance of the
system. The amplifier used to drive the system has a minimum operating headroom of 6 dB referenced to the RMS voltage.
5 The maximum output level of the loudspeaker system is calculated based on the sensitivity and the power handling capabilities of the
system.
6 The coverage angles for the loudspeaker system are taken as the -6 dB points of the directivity response and averaged from 500 Hz – 16 kHz.
7 The minimum impedance of the loudspeaker system is taken over its intended band of operation.
8 The distortion measurements of the loudspeaker system are performed at a distance of 1 m with RMS input voltages corresponding to 1%
and 10% of rated system power handling calculated using minimum system impedance. The distortion percentages are log based averages
from 300 Hz – 3 kHz.
9 Before attempting to suspend the loudspeaker system, consult a certified structural engineer. This loudspeaker system can fall from
improper suspension, resulting in serious injury and property damage. Suspend this loudspeaker system using no less than two of its
suspension points. Maximum enclosure rigging angle is 45°. Use only the correct mating hardware, forged shoulder machinery eye bolt, Mil
Spec MIL 51937-3. All associated rigging is the responsibility of others.
