SB Acoustics Satori TW29BNWG-4 Tweeter

Description

SB Acoustics Satori Beryllium TW29BNWG-4 Dome Tweeter with waveguide

The new Satori Beryllium dome tweeter has arrived!

Beryllium is known for its open and spatial sound, often described as holographic. The self damping properties of Beryllium allow for an extended response without a huge spike in the response at higher frequencies seen in most metal dome tweeters. All dome materials have a different tonal and spatial presentation. Beryllium has a real positive difference, providing a experience unlike all other dome materials.

This is the Satori TW29BN-B Beryllium Dome Tweeter 8 ohm loaded in an aluminum waveguide.

Overall flange diamter: 170mm
Cutout: 146mm
Flange thickness: 5.25mm

• 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
