We TAKET launched headphone H1 and super-tweeter BAT1 in 2004. We used
high polymer piezo-electric film in the headphone, super-tweeter and woofer hi- definitioner
for the first time in the world.

We realised the fact that a micro sound component influences the texture of the overall
audible sound strongly. And we have found that we can reproduce this effect surely,
even though the sound pressure level (SPL) of our Batpure supertweeter is 70dB and
for our WHDPURE is 50dB. In a word, humans have the ability to detect
the micro starting part of the sound which contributes to make the reality of sound reproduced.

There are other differences between real sound and reproduced audio sound. For example,
the sound at the center is thin in stereo sound, even if the center is the leading part in
the real soundstage. And there is a rough or misty texture with no sound space in the stereo
soundstage, and it has been thought that this is the fate of stereo sound.

Some multi channel systems have tried to partly solve these problems. Certainly total
soundstage may be extended, but it is an opaque and flat soundstage that is extended
as a result. So some audiophiles prefer to listen to monaural audio sound.

At TAKET we thought that the center of a sound source is to be distributed equally
to L and R stereo channels. However, hesitation is caused in the human brain as to
whether the sound of the channels is the same or not, because there is a micro difference
between signals of L and R caused by gaps among the recording, reading, and the phase of
signal etc.

We thought this is the main reason which makes the disappointing difference between
real sound and stereo recorded sound. If so, it might be solved when our brain can confirm
that both sound signals of L  and R are from same origin. So, we marked same sign to
both signals by connecting and micro mixing of L and R signals of amplifier just before
inputting to both speakers. Then, an effect that far exceeded our expectation was born.
We completed the TakeT-SA design by adding our knowhow technology to this micro mixing.

This micro mixing technology will make a big improvement not only to stereo reproduction
but also multi channel reproduction in the future. Furthermore, we think that the reality
of reproduced sound image and soundstage will be changed greatly if it is used
in the TV and theater.

Of course, the reality of the soundstage and the quality of the sound can be improved
preeminently by the synergy effect when our super-tweeter and woofer-hi-definitioner
are combined.
