Description
New in the premium SB Acoustic Satori line is the 4 ohm version of their premium tweeter with Neodymium magnet and TeXtreme dome.TeXtreme is an advanced, super thin carbon fibre fabric that maximises the strength-to-weight ratio.This unit features smooth frequency response allowing for minimal effort in network design.
Features
- Advanced TeXtreme® dome
- Two part aluminium faceplate with integrated mechanical decoupling
- Dual balanced compression chambers for improved dynamics
- Dual copper caps for absolute minimum voice coil inductance and minimum phase shift
- High saturation neodymium motor system with T-shaped pole piece for lower distortion
- Non-reflective cast aluminium chamber with optimised damping for improved dynamics
- Shallow flow optimised magnet structure for optimum coupling to rear chamber
- CCAW voice coil for low moving mass
- Long life silver lead wires
- Low resonance frequency for extended range
