Description
A 5" mid-woofer from SB Acoustics with a geometrically reinforced ceramic cone in a vented cast aluminium chassis. It has a soft low-damping rubber surround, a CCAW voice coil on a fibreglass former and a copper sleeve on the vented pole piece for low inductance and low distortion.
Features
- Vented cast aluminium chassis for optimum strength and low compression
- Geometrically reinforced ceramic cone for optimum piston operation and reduced break-up
- Soft 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
- Long life silver lead wires
- Vented pole piece for reduced compression
