SB Acoustics Satori MR16PNW-4 Midrange Speaker

SB Acoustics Satori Logo

The SB Acoustics Satori MR16PNW-4 is a high performance 6½ inch 4 ohm midrange loudspeaker drive unit featuring a unique composite cone made of paper and Egyptian Papyrus™ fibres. This drive unit is essentially the same as the MR16P-4 but features an undyed cone presented in it's natural finish. The colourant added to the MR16P-4 adds a touch of damping at the upper frequency extreme as can be seen if you carefully compare the frequency response graphs.

Also available in 8 ohms: MR16PNW-8

Key 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.
  • Long life silver lead wires attached 180° apart for improved stability.
  • Vented pole piece and coil former for reduced compression.
  • Gasket and bolt hole protrusions for reduced coupling to speaker cabinet.
  • CCAW voice coil for reduced moving mass.
  • Mode balanced cone for reduced break-up.
