SB Acoustics SB23NBACS45-4 Aluminium Woofer

The SB Acoustics SB23NBACS45-4 is an 8 inch 4 ohm woofer / bass speaker featuring an aluminium cone, a 45mm voice coil and a shallow profile vented cast aluminium chassis. The cone features geometric reinforcing ribs which control diaphragm breakups / bell modes allowing for a smoother extended frequency response. A versatile unit designed for applications with restricted rear depth.

Also available in 8 ohms: SB23NBACS45-8.
