Description

A 3" full-range driver from HiVi's B Series, with a one-piece aluminium alloy cone in an antique bronze anodised finish, a rubber surround and a magnetically shielded ferrite motor. HiVi suggests it for the centre and surround channels of small home theatre systems and for computer speakers.

Features

  • One-piece aluminium alloy cone with a damping-layer treatment and an antique bronze anodised finish
  • High-compliance CONEX suspension for stiffness and dynamic stability
  • High-temperature Kapton voice coil former with a CCAW voice coil, stable under high load
  • Shielded magnetic circuit with long linear travel, optimised by finite element analysis
  • HiVi's symmetrical magnetic field drive for lower distortion
  • Narrow high-strength frame to reduce parasitic resonance
