Lightweight carbon fiber blades firmly attached to the rear of each active alloy cone serves to both strengthen the cone and quiet it. The twin 12” (300mm) active drivers now offer an additional 12mm of stroke and also benefit from updated suspension geometry and greater power handling. And a brand-new double-spider, high powered passive unit on the bottom delivers floor rippling low bass. The result is a major step forward in the 212 design, an already brilliant performer now playing louder with greater ease whilst better preserving the tiniest details of air and space with even greater precision.
