Infinity Kappa 104.7W

Woven Glass-Fiber Cone material is extremely stiff, minimizing cone flex; this results in very low distortion and improved clarity that Infinity trademarks. Selectable Impedance provides easy configuration of the voice coils. No more confusing series and parallel connections of voice coils and easier connection for multi-subwoofer systems. Neodymium motor with aluminum heatsink provides a heatsink for the motor's steel parts. Neodymium provides more magnetic energy in a smaller space, which reduces overall weight, and is inherintly magnetically shielded. 3-inch diamter voice coils provides better thermal power handling than smaller sized voice coils. Vented Polepiece reduces air compression under the dustcap, which minimizes mechanical noise and provides more constant mechanical Q for reduced distortion. Medium Q Design provides great performance in sealed, vented or bandpass enclosures. Sealed enclosures for Kappa woofers can be + or - 30% of the recommended volume. Optimum vented boxes do not require super-long ports.
