Active crossover feature

[ogs]

Hi Ogs,

by six ports I though of 3 channels (low, mid and high). Basically, low and mid could be declared as L and R (as they are now), but if you get another D200 you could use it as 3way active crossover. In that case L would become Low, R would become Mid. One D200 for left channel the other D200 for right channel. Only thing missing at the moment is one more channel (for the highs).
In regards to the needed power, I believe only LF would need more power. That leaves you with current two channel as it is and a very small extra power amp for the highs. I don't think the size need to increase, and if so it should be minimal.
Last part would be to add something like this: http://www.minidsp.com/products/audio-pl...ced-detail in the configurator.

Does it make sense?

Sure it makes sense. For six channels you'll need three D200 or maybe two D200 and a D120. Then you'd need a DEQX HDP-5 with Reference Calibration Kit for speaker unit correction and advanced cross over design. The built in cross over function in the Devialet amps would be inadequate for this task as it does not contain group delay correction or equalising for individual drive units. The difficulty getting this to sound good would be massive.

We are talking more than 25.000 Euro before cables. This would certainly be great fun and I am sure it could sound fantastic if done correctly, but I do not think it is realistic. It would be sort of scaled down version of the B&W Nautilus + eight mono blocks set up that Devialet has used in some shows. In Munich it did not sound too good either according to reports here and elsewhere.
