AuraSound Speakers
-
AuraSound, Inc. specializes in the production of high SPL, bass-rich, low distortion sound from compact transducers.
-
AuraSound's Neo-Radial Technology (NRT)- a unique teardrop-shaped motor structure- offers unconventional design and unsurpassed efficiency and performance. This allows louder play and more bass while generating substantially less distortion than ordinary loudspeakers.
-
Designed for extremely long throw, high efficiency, and high power capacity.
-
Unsurpassed linearity and exceptionally low harmonic distortion.
-
Aluminum alloy cones: much higher stiffness-to-weight ratio than traditional paper or polypropylene.
-
Virtually no magnetic leakage, even better than the best shielded drivers. Ideal for home theater applications.
-
Lower weight and smaller size.
-
Underhung voice coil totally controlled by the magnetic system.
-
AuraSound NRT Subwoofers set a new standard for bass performance!
