Features:

• Ribbon tweeters used in this system can give a wide frequency
  response up to 40KHz, which guarantees high fidelity and nice
  sound coverage.
• The tweeter's impedance and phase response curves are almost
  as flat as ideal horizontal lines. The moving mass of the
  transducer only weighs milligrams therefore ensures excellent
  transient response!
• Utilization of unique thin foam surround and specially coated
  paper cone results in efficient reduction of distortion rate.
• The rigging part is designed to meet different application
  requirement. The splay angel can be adjusted by minimum 1°
  vertically.
• The active subwoofer is the result of combination of low
  distortion loudspeaker technique, linear amplification technique,
  and DSP audio processing technique. Input signal is amplified
  by the built-in pre-amplifier, then processed and distributed
  by DSP, finally output via power amplifier to the subwoofer
  and the full-range speaker, all of which forms an integrated system.
