The new AuraSound NRT Subwoofers set a new standard for bass performance. Designed for extremely long throw and high output, all four models feature Aura's patented Neo-Radial Technology (NRT) magnetic structure yielding unsurpassed linearity and exceptionally low distortion. The cones are made of aluminum alloy, which has a much higher stiffness-to-weight ratio than traditional paper or polypropylene cones. This allows the cones to resist deformation in small enclosures and to withstand the abuse of competition use. It also allows the cones to operate as true pistons at all power levels ensuring the best performance from whisper levels to thundering SPL contests.


Mobile Reference Subwoofers
featuring NRT Technology
Mobile Reference subwoofers feature AuraSound's proprietary NRT technology and are designed for extremely long throw and high output, all four models feature Aura's patented Neo-Radial Technology (NRT) magnetic structure yielding unsurpassed linearity and exceptionally low distortion.

The cones are made of aluminum alloy, which has a much higher stiffness-to-weight ratio than traditional paper or polypropylene cones. This allows the cones to resist deformation in small enclosures and to withstand the abuse of competition use. It also allows the cones to operate as true pistons at all power levels insuring the best performance from whisper levels to thundering SPL contests.

To control the cone/voice coil assembly under excursion, a three-suspension system is utilized and is comprised of the large rubber half-roll surround and dual oversize composite spiders. The voice coils are made from custom edgewound aluminum wire for maximum efficiency and are manufactured with very high temperature materials and adhesives for very high power handling. The spiders are ventilated to reduce backpressure and the resulting distortion it causes. Custom die cast aluminum frames were developed to provide the excursion capabilities these woofers require, and to offer a strong and rigid structure to handle the abuse of on the road use. A distinctive industrial design featuring the first mobile audio application of color shifting "ChromaFlair" paint sets these woofers apart visually, just as their sound does sonically.
