Magnetic Liquid Suspension (MLS™)
The Magnetic Fluid used in all NEAR speakers was developed especially for NEAR
MLS means better music enjoyment
Magnetic Liquid Suspension (MLS) was patented by New England Audio Resource (N.E.A.R.) and is a superior method for guiding a speaker's voice coil assembly through the magnetic field. This technology is used throughout the NEAR® product line to yield exceptional sound quality.
MLS eliminates the traditional mechanical "spider" and replaces it with an advanced low viscosity magnetic fluid that stays permanently suspended in the gap of the magnet, allowing the voice coil to remain centered and to operate with superior linearity. In fact, the louder it plays, the more accurate the centering forces become. The results are lower distortion, greater linearity, more consistent long-term performance and longer cone excursions. This allows the use of smaller diameter woofers without sacrificing bass extension.
Clarity at every volume
Without the burden of overcoming the resistance of mechanical spiders, MLS woofers respond more quickly to musical impulses for the kind of clarity and minute detail retrieval usually found only in ultra high-end indoor speakers. What’s more, the clarity and detail are there even at low volume levels and at every ambient temperature. Where traditional speakers don’t start sounding good until cranked to a moderately loud level, NEAR speakers sound clear and intelligible from late-night whisper to rock concert loud. Where traditional speakers perform poorly in extreme heat and cold, NEAR speakers sound great from below freezing to desert hot (-20 to +160 degrees F; -29 - +71 C). There’s nothing like ice fishing to the sound of Reggae pumping from your NEAR speakers.

Rock solid reliability
MLS also contributes to NEAR speakers’ legendary reliability. The fluid prevents debris from entering the gap, preventing rubs and buzzes that drive homeowners and integrators crazy. In addition, the fluid draws heat from the aluminum voice coil, increasing power handling and reliability as well as minimizing impedance shifts that roughen frequency response and lead to compressed sound. Lastly, MLS eliminates other failure opportunities – that of the spider material breaking down due to temperature and humidity stress, and failure of the glue used to secure the spider to the basket and voice coil. Unlike fabric spiders NEAR’s magnetic solution does not break down or change in any way, even when subjected to years of environmental stress. NEAR speakers perform consistently year after year after year. |

MLS Benefits
- Voice coil is constantly centered as it moves, for lower distortion
- The magnetic fluid draws heat away from the voice coil for better reliability and performance
- Eliminating the mechanical spider eliminates a major source of speaker distortion
- Constant lubrication of the gap prevents oxidation, even in outdoor uses
- Magnetic fluid maintains constant compliance over a wide range of ambient temperatures
- Longer excursions are possible using smaller diameter woofers, without sacrificing bass extension
