Description

A 5" mid-woofer from SB Acoustics with a woven carbon fibre and Rohacell® sandwich cone, a rubber surround and a ferrite motor, in a vented cast aluminium chassis. The voice coil is CCAW on a fibreglass former, and the vented pole piece carries a copper sleeve for low inductance and low distortion.

Features

  • Rohacell®/Carbon fibre sandwich cone for optimised stiffness/damping ratio
  • Vented cast aluminium chassis for optimum strength and low compression
  • Low damping rubber surround for improved transient response
  • Non-conducting fibre glass voice coil former for minimum damping
  • Extended copper sleeve on pole piece for low inductance and low distortion
  • CCAW voice coil for reduced moving mass
  • Long life silver lead wires
  • Vented pole piece for reduced compression
