NEAR’s exclusive MDT™ metal-alloy diaphragm is about as light as is physically possible – nearly the ideal
massless piston. The benefits are immediately recognized in the musical accuracy, fine detail of sound,
and ease of listening. Here is a summary of MDT benefits:
• 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
In addition to MDT, another unique technology is incorporated into NEAR speakers: Magnetic Liquid
Suspension (MLS™). MLS eliminates the traditional mechanical centering device (the “spider”) for the
voice coil and replaces it with a magnetic fluid that remains permanently suspended in the gap of the
magnet, allowing the voice coil to stay centered and to operate with extreme linearity. In fact, the louder it
plays, the more accurate the centering forces become. Here is a summary of MLS benefits:
• Voice coil is constantly centered as it moves up and down, for lower distortion
• Voice coil is more efficiently heat-sinked by fluid instead of air
• Dual-layer voice coil with separate inner and outer windings reduces distortion at high output levels
• Greater linearity is accomplished because the mechanical spider is eliminated
• Constant lubrication of the gap prevents oxidation from outdoor use
• Long-term operation is more consistent since fluid doesn't change characteristics
• Longer excursions with smaller diameter woofers; spiders limit excursions
