GENERAL PRODUCT DESCRIPTION
The LF215-4A is a dual 15" / 380mm subwoofer with the same
footprint as the Altec Lansing DE6412 and DE9412 Duplex
full-range speaker systems. In addition to its use with Altec's DE
& DS-series full-range speaker systems, the LF215-4A can be easily
incorporated into component-based sound systems. The
LF215-4A has been designed to provide extended low frequency
performance in Auditoriums, Performing Arts Centers, Houses
of Worship, or any facility requiring low frequency reinforcement
for full-range music reproduction.
Two of the Altec model 4156-8A 15" / 380mm woofers
are used in the LF215-4A. The drivers may be connected in
parallel (for a single four ohm load) or driven individually (for
two, eight ohm loads) via a switch and separate driver inputs.
This robust component has been designed to deliver tight,
punchy low frequency reproduction in vented speaker cabinets.
The 4156-8A has a corrosion resistant die-cast frame and
moisture-resistant cone for maximum durability in all
environments.
The 13-ply birch plywood enclosure is paintable, and features
steel reinforced suspension points. Altec Lansing includes a
forged eyebolt suspension kit with each subwoofer. Input
connections are via barrier strip or Neutrik
The LF215-4A is offered in either charcoal grey or white, with
contrasting cloth covered metal grille. Altec Lansing includes
neutral grille cloth with each subwoofer, allowing you to dye the
cloth to integrate the subwoofer into the surroundings.
The LF215-4A is designed to work in conjunction with Altec's
DE6412 and DE9412 Duplex
systems. Presets are available for the Altec Lansing 4048A
4-in x 8-out DSP Processor, allowing the system designer to easily
incorporate the LF215-4A into multi-channel applications.
