The HiVi E8 is a well engineered, high quality mid-bass that will work well in numerous applications. The black natural fiber cone is lightweight and stiff, but well damped for extended useable frequency response. A large ferrite motor and a Qt of 0.32 means this will work optimally in smaller ported enclosures. The aluminum voice coil former increases power handling and the cast frame will make this a durable woofer for years.Â
