SB Acoustics SATORI TW29BNWG-4

SB Acoustics SATORI TW29BNWG-4 Beryllium Dome Tweeter

• Beryllium dome for non-resonant high frequency extension
• 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  optimized damping for improved dynamics
• Shallow flow optimized 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
• Solid aluminium waveguide
• Controlled directivity
• Adapter ring for bolt-less mounting to driver
