The SB Acoustics SB23CACS45-4 is a 8 inch 4 ohm woofer / bass speaker featuring a geometrically reinforced ceramic cone, a low distortion motor system and a vented cast aluminium chassis. The ceramic layer is bonded to an aluminium substrate, this combination of materials results in an excellent stiffness to damping ratio. A very low distortion design for applications with restricted rear depth.
Also available in 8 ohms: SB23CACS45-8.
Soft low damping rubber surround for improved transient response.
Geometrically reinforced ceramic cone for improved break-up control.
Shorting ring in motor system for reduced distortion.
Vented pole piece for reduced compression.
Vented cast aluminium chassis for optimum strength and low compression.
Non-conducting fibre glass voice coil former for minimum damping.
CCAW voice coil for reduced moving mass.
Long life silver lead wires.
