The DnD12 is a compact and efficient two-way sound reinforcement
loudspeaker system. The enclosure of the DnD12 is a multi-angle cabinet that can be employed as a stage monitor (at either of two angles) or
upright as a front-of-house speaker system. The low frequency driver in
the DnD12 is a high power, high efficiency 12" woofer. The high frequency Focused Array section is a unique dual driver pattern control
horn. The two HF drivers are angled in the vertical plane to maintain a
constant vertical coverage pattern at all frequencies.The pattern control
design of the DnD high frequency horn also maintains a constant coverage pattern in the horizontal plane, thus preventing the beaming (extreme
narrowing of coverage pattern) often found in systems of this type.
The DnD systems are equipped with a very effective PowerSense Plus™
two-stage protection system. This protection system virtually eliminates
driver damage due to over-powering. If excessive power is applied to a
DnD system, the first stage of protection will be activated. Output level of
the speaker system will be reduced by 3 dB, and a red LED indicator on the
input panel will be illuminated. If the power applied to the system remains
at this level, the system will continue to operate in the first stage protect
mode. If the power is increased beyond this level, the system will activate
the second stage of protection, which results in a large reduction in output
level and completely protects the drivers from any power applied.
The DnD12 enclosure is covered in rugged black carpet. The perforated
steel grille is specially formed to provide both increased stiffness and an
attractive appearance.The enclosure is equipped with a stand socket for
use with a speaker stand, and is also equipped with three mounting points
for fixed installation using Community's accessory mounting strap kit.
