NRT Subwoofers
NRT Subwoofers
Originally introduced by Aura as the 1808, the AuraSound loudspeaker transducers
are considered by many audio enthusiasts and specialty loudspeaker manufacturers
to be the best available. From the miniature NSW1Cougar to the enormous NS18
woofer, all feature AuraSound's patented NRT magnet structure for maximum
fidelity with life-like dynamics and minimal distortion. Magnetic shielded
is inherent in the NRT magnet structure.

Specialty Transducers
NRT Subwoofers 
AuraSound Specialty Transducers are unique products that have evolved from
the legendary AuraSound 1808 sub woofer and benefit from recent AuraSound
research and development into small transducers utilizing patented NRT and
Whisper technologies. AuraSound transducers are considered by many audio enthusiasts
and specialty loudspeaker manufacturers to be the best available, bar none.
From the miniature NSW1 "Cougar" to the enormous NRT18 woofer, all
feature AuraSound's patented NRT magnet structure for maximum fidelity with
life-like dynamics and minimal distortion. Magnetic shielded is inherent in
the NRT magnet structure.
AuraSound's Whisper technology embodied in the NSW1 and NSW2 features large
voice coil, miniature speakers which have excellent excursion and high power
handling and surprising bass performance for their diminutive size.
