Description

SB Acoustics MR13P-4

Features

  • Vented aerodynamic cast aluminium chassis for optimum strength and low compression.
  • Proprietary cone material with EGYPTIAN PAPYRUS™ fibres made in-house.
  • Soft low damping rubber surround for optimum transient response.
  • Advanced BIMAX spider for improved linearity.
  • Powerful optimized low distortion neodymium motor system.
  • Non-conducting fibre glass voice coil former for minimum damping.
  • Extended copper sleeve on pole piece for low inductance and reduced distortion.
  • CCAW voice coil for reduced moving mass.
  • Long life silver lead wires attached 180° apart for improved stability.
  • Vented pole piece and coil former for reduced compression.
