Product Details

Aura Cougar NSW1-205-8A 1" Extended Range Speaker Driver

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 4.5 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. Factory buyout, supplies are limited to parts on-hand.

Aura Cougar NSW1-205-8A 1" Extended Range Speaker Driver

I bought a pair of these to build two indiscreet enclosures underneath my daughters loft bed. What is the optimal enclosure volume to use this as a standalone full range speaker?

Asked by: Menace Kustoms
The optimal size for something like this would have internal dimensions of 2"H x 12"W x 6"D with two 1" diameter ports that are 1" long. This will give you a tuning frequency of 160 Hz.

Could these be used in a scaled down cbt array, similar to Don Keele's cbt36? I would be using them as desktop monitors.

Asked by: imthgimp
Yes.

can i use 2 of these drivers with a small passive radiator?

Asked by: jazg
Unfortunately we do not have a passive radiator small enough to use and provide a reasonable response curve. The 3" Peerless with no weigh will tun the enclosure to about 50 Hz which is far too low for these drivers. You are much better off using a standard ported enclosure.

Weird question: is the back of this speaker magnetic, or shielded? I would be using it in an application where I need it to stick to a metal plate or bracket.

Asked by: spp1680
While the speaker is not specifically shielded the magnetic force is aimed at the voice coil gap, so unfortunately this will not stick to a surface with the magnet alone.

Thinking about using 2 of these in a small ported box for a portable jambox style unit. What would be the optimal volume and port size

Asked by: TheJudge
The recommended box for a pair of these would be 0.063 cubic feet (4"H x 10"W x 5"D using 1/2" MDF) with two 1" diameter ports that are 1-3/4" long each. This will tune the box to 160 Hz and provide an F3 of 130 Hz.

I have to ask. Would it be even remotely logical to use two of these as a pair of headphones?

Asked by: chuzzle44
You could certainly try. These are quite a bit different than standard headphone elements so the response in the ear may not be as good as something designed for it.
