The Challenger Series II C-18LF has been designed to provide very high
acoustic output from 40Hz to 120Hz. This 18 inch (476mm) diameter
woofer has an optimized efficiency/bandwidth product that provided
maximum efficiency with standard sound reinforcement frequency
range requirements for subwoofer applications. It is typical to band
limit large format touring systems and permanent installation public
address systems to prevent the input of damaging ultra low frequency
material. Because this low frequency protection is generally set to the
range of 40Hz the C-18LF has been optimized to provide maximum
output in the typical operating range.The large diameter voice coil
design features a 4 inch (101.6mm) voice coil diameter and large cross
sectional area coil for maximum heat dissipation.The C-18LF alsofeatures
an aluminum based edge wound voice coil construction.
The C-18LF is a Ferrite magnetics based design that also features a
rugged aluminum die cast chassis.The mechanical suspension system
has been optimized for high linear displacement within the rated operating
range and input power rating of the transducer.
This high efficiency design will produce high impact bass performance
and is well suited for touring sound applications and permanent installation
systems where live music is the dominant input signal. |
