Vivid Audio Giya G3, puis Kii3+BXT, puis Magico S3 mkII dans une pièce dédiée

[renan]

Merci Nicoben pour le retour.

Cependant tu ne peux pas mettre en cause les integrateurs de systemes purify vs les Kii car un ampli externe qui controle toute les voix ne pourra faire ce qui est fait dans les Kii
tu trouvera des details là sur le controle en courant qui est en usage dans les kii et que tu ne peux pas faire sur un ampli externe.

Ce système n'est pas dépendant de la charge

A second neat idea that the Kii Three employs, and one that seems to have passed by most manufacturers of active speakers, is not one of Bruno’s but was described by Dr Malcolm Hawksford of Essex University in a paper presented to the Audio Engineering Society in 1989. The technique goes by the name ‘current drive’, and involves placing a small resistor in series with the driver and using the voltage measured across it (which will be proportional to the current flowing through the driver voice coil) as a feedback signal. In a conventional arrangement, an amplifier will deliver any amount of current required to make the output voltage follow the input voltage. A current drive amplifier, however, will compare the input voltage with the measured output current and adjust the output voltage to make sure they track. So, now, the output current depends only on the input voltage and not the load. The amplifier delivers any voltage required to make the output current track the input voltage. The primary advantage of current drive is significantly reduced distortion, especially that caused by non-linearities in a driver’s magnet/voice-coil system.
