SB Acoustics Satori TW29 BN-B Beryllium

Beschreibung

The  SB Acoustics SATORI TW29 BN-B dome tweeter with beryllium membrane sets new standards in terms of high frequency performance. The SATORI TW29 BN-B Beryllium is capable of reproducing frequencies up to 40,000 Hz and, with a resonance frequency of 750 Hz, can even be used in a 2-way system.

Beryllium is known for its open and spacious sound, often described as holographic. The self-damping properties of beryllium allow for an extended frequency response without the large peaks in the frequency response at higher frequencies found in most metal dome tweeters. All dome materials have a different sonic and spatial presentation. Beryllium has a real positive difference and offers an experience that is different from all other dome materials.

Features: 

• Beryllium dome for resonance-free high-frequency extension
  
• Two-part aluminum front panel with integrated mechanical decoupling
  
• Two balanced compression chambers for improved dynamics
  
• Double copper caps for absolutely minimal voice coil inductance and minimal phase shift
  
• Highly saturating neodymium motor system with T-shaped pole piece for lower distortion
  
• Reflection-free cast aluminum chamber with optimized damping for improved dynamics
  
• Flat, flow-optimized magnet structure for optimal coupling to the rear chamber
  
• CCAW voice coil for low moving mass
  
• Durable silver wires
  
• Low resonance frequency for extended range
