Genuine Acoustic Research Phantom series 5.25 Illusion Carbon Series woofer, part AR010001. This is the woven carbon-fiber, shallow-mount long-throw driver developed with Illusion driver technology for the discontinued AR Phantom Series. Front-mounted neodymium magnet, aluminum edge-wound voice coil. These are long out of production with no factory replacement source – Illusion left the US market and AR changed hands – making them ideal for restoring a Phantom system with a damaged or blown woofer.
