• Your conventional speaker is made of a rectangular box, woofer, squawker, tweeter,some insulation and a dividing network that separates the output into low, mid, and high range sound.
  
• With this kind of system, it's impossible to reproduce the original sound perfectly because inside the speaker box, the air is full of "dirty sound" – standing sound waves, diffracted sound, and reflected sound that can escape through the speaker diaphragm itself, blending with and corrupting the music.
  
• Even if you listen to a high-end audio system, what you're actually hearing is a medley of noises made by the amps, equalizers and the speakers themselves... not the pure, unadulterated source of the music.
  
• Sounds crumble and nuances get lost within traditional audio systems. The dynamic range shrinks while the volume of the sound dwindles. Fine musical tones become inaudible, resulting in what we call the "entropy of fidelity."
  
• Preventing sounds from crumbling and vanishing is the goal we set for ourselves when we created TimeDomain speakers.
  
• TimeDomain audio extracts 100 percent of the sound on the CD, DVD, or other medium as it was originally recorded.
  
• Playing high quality recordings on our TimeDomain speakers will deliver a true sound image that allows you to hear not only the tone of each individual instrument and voice, but you can also sense where the performers are positioned in relation to each other, you can hear their breathing and the acoustics of the surrounding atmosphere such as the concert hall or recording studio.
  
• For this reason, TimeDomain is the closest you can get to live music.
  
• Speaker Construction
  
• The TimeDomain Yoshii 9 speakers have an unusual shape for a very good reason. The single-piece aluminum cylinder suppresses unwanted vibrations so that only the purest of sounds are emitted.
  
• Inside the tube is the speaker itself, not bolted in but set face up at the top and buffered by a gel material. A heavy plumb bob is suspended from the speaker inside the tube, again to minimize vibrations.
  
• The Yoshii 9's speaker units are set facing upwards so sound doesn't have directionality. In standard speakers, the sounds come from the front of the box. If you move to the sides or behind the speaker, the sound changes and deteriorates.
  
• Not so with the Yoshii 9. The tube construction sends the sound upwards where it spreads throughout the room, allowing you to experience music similar to the acoustics of a concert hall.
  
• Meanwhile, sound waves emanating from the back of the speaker will flow downwards and be released through the bottom of the pipe without affecting the quality of the frontal sounds. What comes out of the front of the speaker is pure, crystalline sound.
  
• For Audiophiles
  
• To express Time Domain theory in more technical terms, the main priority of conventional speakers is to improve the amplitude-frequency characteristics, which does not result in any real enhancement of the phase-frequency characteristics.
  
• But Time Domain theory reproduces the original audio waveform, which contains the amplitude / phase frequency characteristics, and emits the original waveform through the speaker unchanged. That's why Time Domain theory is considered an effective way to attain truly original sound reproduction.
  
• So if you use our speaker system to listen to a sound source that was recorded under less than ideal conditions, those unpleasant sounds will be conveyed as accurately as the desirable sounds.
  
• On the other hand, sound sources that have been recorded under optimal conditions deliver a true sound image, which allows you to hear everything on the recording perfectly.
  
• Looking Ahead
  
• We believe that with the wider recognition of Time Domain theory and an increasing demand for excellent audio, recording technologies themselves will undergo some dramatic changes in the years ahead so that the sound recordings produced by the music industry will be equal to the quality delivered by TimeDomain speakers.
  
• Our TimeDomain products are on the leading edge of that movement.
