Active Kudos Titans w/Devialets?

@Confused ?

You have a very fine memory sir!

I too vaguely remember this, but better than a vague memory, I found the original post(s):

I think there is a key point to keep in mind when considering multi-amp / active type set-ups. There are basically two ways of doing this. One is to use multiple amps, for bass, mid, treble or similar, and keep the speakers crossover electronics. The second way is to remove the crossover electronics and use filters in the amp to mimic the crossover.

The second approach is theoretically superior. Yet there is more. There was some discussion about this at a Deviaet event a few years ago. The Devialet guy explained that with electronic crossovers, it is not possible to fully create the "perfect" crossover, there are limits and compromises. However, if a given speaker manufacturer provided Devialet with details of the perfect crossover, including frequency and phase characteristics and similar, then Devialet could actually create this perfect crossover using the DSP within the Devialet. From a technical perspective, this in theory is the approach that would yield the best results.

With a bit of searching, I found one of the posts I made after the Devialet event:

I have remembered another point that was made during one of the side meetings after the main talk.  This was relating to Devialet's initiative to provide fully active, speaker specific systems.  I was told that Devialet are currently in discussion with a number of speaker manufacturers regarding bespoke active amplification.  How this was explained to me was that speaker crossovers can only subtract from the signal, if the crossover function is performed by the Devialet, it can add, subtract, correct phase and so on.  So Devialet would liaise with the speaker manufacturer, establish from them the perfect "digital" version of the crossover for a given speaker, this is then programmed into a number of Devialet's to produce an active system.  I asked if this was one of the reasons behind the new 210 Pro dual mono, so to provide a lower cost dual mono that might be used for tweeter duties in an active set-up.  Apparently this is not the case, with one issue at the moment being that the different model types cannot be "chained", so you cannot chain a 1000 Pro with a 440 Pro, for example.  This is why the Vivid set-up at Munich had 1000 Pro's with a D250 on tweeter duty.  In theory, using a 440Pro for the HF would be better, having more power and the benefit of dual mono, lower distortion etc.  

This "ultimate" approach, in true Devialet style, has it's own TLA and white paper:

(although for Euro 160000, it is not the most cost effective solution)
