• Heavy-gauge aluminum bracket
• Corrosion-resistant driver frame & mounting hardware
• Attractive styling with "Armadillo" ridges for stiffness
• Coaxial speaker system
  
  

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
