AuraSound Cougar NSW1-205-8A 1" Extended Range Driver 8 Ohm
The AuraSound "Cougar" NSW1-205-8A 1" extended range driver is packed with next-gen speaker technology. An NRT™ neodymium radial magnet motor submerses the 20 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 20,000 Hz. The low, 220 Hz free air resonance combines with 2.25 mm of Xmax (9 mm maximum peak-to-peak excursion) to allow for low crossover points, meaning you can pair the Cougar with nearly any woofer up to 5 feet away (2-1/2 ft. is the recommended maximum) seamlessly.
AuraSound built the NSW1-205-8A 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 Cougar's output is increased from 78 dB 1W/1m to roughly 84 dB 1W/1m, with power handling increased to 20 watts RMS. Grouping eight together, and wiring for 4 ohms, yields roughly 90 dB of output at 1W/1m with power handling increased to 40 watts RMS.
Adding a series 80 microfarad capacitor creates a 250 Hz, 1st-order high pass and increases power handling. When wired in pairs or groups for a 4 ohm load, use a series 160 microfarad capacitor for the same effect.
