SB Acoustics logo

The SB Acoustics SB17CRC35-8 is a 6 inch 8 ohm midwoofer drive unit featuring a composite woven Carbon fibre / Rohacell® sandwich cone; this space age material has a superb stiffness to weight ratio with high internal damping.

Also available in 4 ohms: SB17CRC35-4

Key Features:

  • Rohacell®/Carbon fibre sandwich cone for optimised stiffness/damping ratio
  • Vented cast aluminum 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
  • Vented pole piece for reduced compression
  • Long life silver lead wires.
