The design of W5a driver based upon a beneficiary idea of an extended pole piece in a magnet system. But here we went further. Using FEA simulation we optimized the complete magnet structure and specifically shaped the pole piece to achieve symmetric flux distribution along travel path of the voice coil. This design approach provides better driving force linearity. It considerably reduces VC inductance modulation and DC offset of a moving system at high power levels. The result is - much less distortion and more effective VC cooling. The cone/surround design is optimized to achieve extended and balanced frequency response without apparent top end resonances. W5a has exceptionally smooth roll-off, which allows easy blending with any type of tweeter even with 1st order crossovers. To avoid air compression and internal air volume resonance the driver has a central phase plug. The plug improves frequency response and dispersion as well. The massive aluminum die-cast frame has been developed to minimize parasitic structural resonances. The shielded magnet structure allows versatile audio/video applications. W5a is a high performance driver, which can be used in a vast variety of combinations in top class speaker systems. Recommended crossover frequency region is 2-3.5 kHz.
