Item(s) for Sale: AuraSound NS3-193-8A 3" Extended Range Driver 8 Ohm
Item(s) Description/Condition: Aluminum cone, high roll surround, neo motor. These things bump, ran with no x-over and was shocked at the sound they produced. Unreal truly excellent sound reproduction, really surprised me.
AuraSound NS3-193-8A 3" Extended Range Driver 8 Ohm
Creating modern high fidelity, low distortion speakers is easy with AuraSound's revolutionary NS3-193-8A 3" full range woofer. The self-shielded, radially polarized Neo-Radial Technology (NRT) motor focuses over 95% of the magnet's energy onto the underhung voice coil, forcing the cone to follow the input signal, reducing distortion.
For longevity, the NS3 is built using an aluminum cone that's mated to the stamped steel frame with a rubber surround. The Kapton® former and copper-clad aluminum wire (CCAW) voice coil help to increase peak power capacity. 9.5 mm of peak-to-peak excursion allows you to use this driver at, and below, the 80 Hz resonant frequency with authority without affecting its top-end response.
