The KW4 series is handcrafted in Austria and combines a solid ferrite motor with a generously sized 4-inch voice coil. The eight-layer aluminum winding is designed for extreme electrical power handling and enables an RMS power handling capacity of up to 6,000 watts\u003c\/span\u003e\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eTo ensure mechanical durability, CZ Audio relies on a particularly sturdy design with a high potential for cone excursion. The KW4 12\u0026#34; achieves a specified Xmax of 40 mm in one direction, making it suitable for applications that require high sound pressure levels combined with powerful low-frequency bass. The current version also features the new TC basket, which is designed for even greater excursion.\u0026nbsp;\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eDepending on the model, the KW4 is available with either a glass-fiber-reinforced paper cone or a carbon cone.
