SB Acoustics SB17CAC35-8 Ceramic Midwoofer

SB Acoustics logo


The SB Acoustics SB17CAC35-8 is a 6 inch 8 ohm midwoofer featuring a geometrically reinforced hard ceramic cone and a 35mm voice coil. The ceramic layer is bonded to an aluminium substrate, this combination of materials results in an excellent stiffness to damping ratio; consequently, the midrange distortion figures are class leading. Like other drive units in the CAC range, the SB17CAC35-8 has a fine detailed sound and is largely impervious to the effects of daylight and domestic humidity making it an ideal alternative to paper / pulp types.

Also available in 4 ohms: SB17CAC35-4

Key Features:

  • Vented cast aluminum chassis for optimum strength and low compression.
  • Soft low damping rubber surround for improved transient response.
  • Geometrically reinforced ceramic cone for optimal piston operation.
  • CCAW voice coil for reduced moving mass.
  • Non-conducting fibre glass coil former for minimal damping.
  • Extended copper sleeve on pole piece for low inductance / low distortion.
  • Vented pole piece for reduced compression.
  • Long life silver lead wires.
