Description
The A12 features unique technologies to produce the highest
sound quality in the most durable and reliable loud
speakers
available.The A12 is a compact, high-powered speaker
that proj-
ects well in open spaces like theme parks, sports fields, and
plazas.
Precise sound reproduction is achieved with two 6.5" mid/bass
drivers employing both MDT and MLS technologies for superior
sound and weather resistance. The high-frequency driver is a 1.9"
horn-loaded diaphragm (1" exit). A built-in 128W transformer
makes the A12 compatible with 70V sound systems. The trans-
former can be easily bypassed for use in low-impedance systems
(16 ohms). Spiderless technology (MLS) and advanced materials
deliver out-of-the-box performance year after year. Speaker
diaphragms are manufactured with materials that will not be
altered by constant exposure to UV rays or water, cold or heat, or
extremely high or low humidity.
MDT (Metal Diaphragm Technology):
• High rigidity and low mass of metal versus traditional
papers and plastics
• Extremely stable cone structure over long periods of time
• Fast transmission of sound through the diaphragm means
low energy storage
• Special anodizing process creates a ceramic coating for
increased stiffness
• Efficient heat-sinking of voice coils under long-term,
high-power situations
MLS (Magnetic Liquid Suspension):
• Voice coil is constantly centered for lower distortion
•
Voice coil is more efficiently heat-sinked by fluid instead of air
• Greater linearity is accomplished because the mechanical
spider is eliminated
• Constant lubrication of the gap prevents oxidation from
outdoor use
