The A12 features unique technologies to produce the highest sound quality in the most durable and reliable loudspeakers available. The A12 is a compact, high-powered speaker that projects 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 transformer 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

• High-powered, all-weather speaker
• High efficiency and power handling for optimal performance
• One model for both 70V and low-impedance systems
• 225W at 16 ohms
• 70V Power settings: 128, 64, 32, 16, 8 watts
• Dual 6.5" metal-alloy MDT mid/bass speaker cones are extremely stable in all environments
• MLS Ferrofluid voice coil suspension replaces distortion-causing mechanical spider
• Horn-loaded, 1" exit compression driver features a 1.9" Mylar diaphragm for consistent long-term performance
• 90° Horn delivers constant coverage over listening area • Dual-layer voice coil with separate inner and outer windings for high output and ultra-low distortion
• Advanced polymer compound surrounds resist UV rays, chemicals, and salt spray
• Gold-plated, rust-proof input connectors
• High-density, injection-molded cabinet resists chipping and scratching
• Low-resonance cabinet structure
• Specially designed vent covers help keep water out
• Heavy-gauge stainless steel mounting yoke with 180° swivel
• Easy-to-grip, oversized mounting knobs
• Speaker mounts with knobs attached for easier, safer installation in hard-to-reach locations
• Corrosion-resistant woofer frames and mounting hardware for long-lasting, like-new appearance
• Black cabinet color, attractive styling using patented Armadillo ridges that improve durability as well as sound
• Adjustable Tilt-Mount Adapter attaches to mounting yoke (Model TMA812, sold separately)
