Voice coil former and heat-resistant SV voice coil wire -Central phase plug -High density aluminum die-cast frame -Symmetric Motor Drive (SMD) technology The design of the W5 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/surround design is optimized to achieve extended and balanced frequency response without intrusive top end resonances. The W5 has an exceptionally smooth roll-off, which allows easy blending with any type of tweeter, even with first-order crossovers. To avoid air compression and internal air volume resonance the driver has a central phase plug. The plug improves top end frequency response as well as dispersion. The massive aluminum die-cast frame has been developed to minimize parasitic structural resonances. The shielded magnet structure allows the W5 to be easily incorporated into audio/video applications. The W5 is a high-performance driver, which can be used in a variety of combinations in top-class speaker systems. Recommended crossover frequency region is 2-3.5 kHz.
