Bi-Amping Discussion


Recommended Posts

Devialet have developed an active crossover system, Devialet AXD, as they call it.  I spoke to Devialet's chief designer at dealer event a while back, the way he explained it was that the speaker manufacturer could specify the perfect design for a given speaker's crossover and Devialet could create this virtually within AXD.  The point being that it is not possible to create the perfect crossover using passive electronics, there will always be compromises in the design, but the "virtual" AXD crossover could indeed be perfect.  Devialet have demonstrated this system, but I have not seen much evidence of the system gaining much commercial success, or for it being offered for a significant range of speakers.  It is an interesting concept, although being cynical you could argue that it is a way for Devialet to sell customers far more amplifiers than they really need.  More details per the links below.
