GENERAL PRODUCT DESCRIPTION

Houses of Worship and Auditoriums require speaker systems that can
accurately reproduce the human voice and not miss a beat when the task
is live or recorded high fidelity music. Standard two-way speaker systems
are adequate, but suffer from cancellations and interference from
adjacent HF and LF sources. Altec Lansing’s solution is a Duplex® single
magnet, point-source component that minimizes these cancellations
without sacrificing speech intelligibility or high fidelity, full-range music
reproduction.

The DX1012-8A uses a unique Duplex

®

ENGINE component featuring a

large format high frequency driver and a 12"/300 mm low frequency
speaker & voice coil mounted to the front of the same magnet structure.
This point-source design means that all of the acoustic energy is
generated in a 1.5" space. The high frequency driver is mated to a 90˚
conical high frequency horn, insuring smooth coverage across the rated
bandwidth.

A 13-ply poplar paintable cabinet has internal reinforced L-brackets
presenting multiple suspension options (horizontal and vertical
orientation). Three forged eyebolts are included with each speaker. The
model DX1012-8A-G is a charcoal gray painted cabinet with contrasting
light gray cloth covered metal grille.

The DX1012-8A-W is a white cabinet with contrasting beige cloth
covered metal grille.

Should you need to paint the cabinet to match the décor of the facility, a
piece of neutral grille cloth is included with each speaker. This grille cloth
can be dyed to match the speaker cabinet color, or to integrate the
frontal area of the cabinet into the architectural space.

Where extended low frequency performance is required in Auditorium
and House of Worship systems, the Altec Lansing Professional model
LF115-8A single 15" flyable subwoofer provides an excellent complement
to the DX1012-8A.
