W10 Hi-end Woofer

-Kevlar? Reinforced paper composite cone
-Optimized-loss Santoprene? Surround with low mechanical memory -CNC machined magnet structure parts for maximum precision
-High power handling 3 inch voice coil with black anodized aluminum former
-Vented pole piece
-High density aluminum die-cast frame with multiple point mounting
-Symmetric Motor Drive (SMD) technology
The design of the W10 driver is based upon the benefits of an extended pole piece in a magnet system. But here we went further. Using Finite Element Analysis simulation, we optimized the complete magnet structure and specifically shaped the pole piece to achieve symmetric flux distribution along the travel path of the voice coil.
This design approach provides better driving force linearity. It considerably reduces voice coil inductance modulation and DC offset of the moving system at high power levels. The result is much less distortion and more effective voice coil cooling. The cone is a paper composite reinforced with Kevlar fibers to insure proper dynamic stability and stiffness.
The surround is Santoprene?, which has a low mechanical memory, providing for more accurate transient response. The large voice coil, high Xmax, and vented pole piece allow for clear and resolving performance without mechanical or thermal compression even at the highest output levels.
The W10 has been optimized to achieve clean, dynamic low bass reproduction at high power levels in compact or medium size vented cabinets. The massive aluminum die-cast frame with multiple point mounting has been developed to minimize parasitic structural resonance. Recommended maximum crossover frequency is 400-1000 Hz.
