The C-12MB has been designed specifically for use as a mid basstransducer.
This 12 inch (315mm) diameter driver has been optimized for
use as either a direct radiator mid bass driver or for use in a hornloaded
mid bass design. The Challenger series II C-12MB is optimized for a
combination of low frequency response and efficiency. The C-12MB
has been designed for maximum efficiency thru the operating range
of 60Hz to 2000Hz.The frequency range of 120Hz to 2000Hz is the
critical mid band range where vocal fundamentals as well as fundamentals
of most musical instruments are found.This area is critical to
system clarity and intelligibility and the C-12MB, with its newly developed
highly damped cone material, is optimized.
The large format 4 inch (101.6mm) voice coil diameter produces alarge
cross sectional area for maximum heat transfer and power compression.
The rectangular geometry voice coil provided a professional level
of power handling and critical reliability. Like all models in the Challenger
Series II, the C-12MB features a large diameter Ferrite based
permanent magnet coupled to an aluminum die cast chassis. Because
of its very high efficiency design, the C-12MB is designed for mid bass
applications only. For system designs where additional bass is required
the C-12MB is a superior choice. |
