Product Details

HiVi M5a 5" Aluminum/Magnesium Midbass

The HiVi M5a has been optimized for an extended and dynamic bass reproduction in vented systems. The driver utilizes a unique one-piece aluminum/magnesium composite cone; the diaphragm's superior rigidity provides immediate and accurate reproduction of transient attacks. This contributes to a more naturally dynamic sound as well as superior definition and articulation in the mid-bass region. Using Finite Element Analysis simulation, Hi-Vi optimized the complete magnet structure and specifically shaped the pole piece to achieve symmetric flux distribution along the travel path of the voice coil, which provides better driving force linearity. It also 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 driver may be used in a small closed box as a midrange unit in a 3-way system and the good extension (50 Hz) in a vented enclosure allows for use in a 2-way two-driver or MTM configured system. Recommended crossover frequency region for a 2-way system design between 2-5 kHz.
