SW312WA03 and SW312WA04 are woofers designed for dedicated sub bass applications. They work equally well for high-end hi-fi, high quality home theater systems, and top multimedia setups. The extremely stiff aluminium cone, the long linear throw, exaggerated ventilation, and the special dynamic linearization short circuiting rings together make up for an unusually linear and low-distortion woofer. Even at very high signal levels, the unit behaves controlled and without distortion. Due to low mechanical losses SW312WA03 and SW312WA04 master equally well low level details and extreme dynamic peaks. Both models are available with black anodized alu cones as SW312WA05 (4 ohm) and SW312WA06 (8 ohm)
