The Aurasound "Whisper" NSW2-326-8A 2" extended range driver is packed with next-gen speaker technology. An NRT™ neodymium radial magnet motor submerses the 32.6 mm, underhung voice coil in magnetic flux for supreme control, low distortion, high output (for its size), and wide frequency range without stray magnetic fields that could potentially damage sensitive electronics, while the extreme venting provided by a capless pole piece evacuates air that would otherwise be compressed (in a driver this size).
A titanium cone is mated to a foam surround to reduce cone breakup, for an extremely linear frequency response from 250 to 15,000 Hz. The low, 250 Hz free air resonance combines with 3 mm of Xmax (6 mm maximum peak-to-peak excursion) to allow for low crossover points, meaning you can pair the Whisper with nearly any woofer up to 5 feet away (2-1/2 ft. is the recommended maximum) seamlessly.
Aurasound built the NSW2-326-8A with a non-resonant, minimalistic, rear-mount frame for close center-to-center placement which is especially important in line arrays to minimize comb filtering. When used in series-parallel groups of four, the Whisper's output is increased from 84 dB 1W/1m to roughly 90 dB 1W/1m, with power handling increased to 60 watts RMS. Grouping eight together, and wiring for 4 ohms, yields roughly 96 dB of output at 1W/1m with power handling increased to 120 watts RMS.
