UK STOCK ITEM

The SB Acoustics SB23NRXS45-8 is an 8 inch 8 ohm woofer / bass speaker featuring a Norex cone, a 45mm voice coil and a shallow profile vented cast aluminium chassis. Norex is a proprietary paper based material comprised of wood pulp and selected natural fibres blended for an optimally strong but lightweight cone that gives extended pistonic action. A versatile unit designed for applications with restricted rear depth.

Also available in 4 ohms: SB23NRXS45-4.

Key Features:

  • Soft low damping rubber surround for improved transient response.
  • Shorting ring in motor system for reduced distortion.
  • Vented pole piece for reduced compression.
  • Vented cast aluminum chassis for optimum strength and low compression.
