Post Subject: Ultra sharp digital filtrations.Posted by Romy the Cat on: 8/6/2013

I still thinking about this ides of ultra sharp digital filtrations and for whatever reasons it fascinates me. It is not the I am consider to do anything with it – it is absolutely not needed for me – still I might like the idea as a topological solution. Some regular digital crossovers I think do allow 20^th order. If you remember in the London’s thread a few days back I told that I would like to hear some French installations. There is, or at least there was, a guy in France, his name is Jean-Yves Kerbrat. He has a large room and he piles a LOT of exotic Japanese drivers in Macondo Configuration and all digital crossovered. I of cause discarded this practice but I never thought though that it might be 120dB per octave that might (or might not) change the rule of the game. I need to call to my digital experts and ask them what and how the120dB per octave filter is implemented on digital domain. I think TACT has 120dB per octave and it would be fun to hear it. I still feel that the “digital” might be heard even with such sharp filter as I did participate in the experiments where I was accurately pointed out the files where dither was applied (at -132dB!!!) . Still, how the driver will sound with 20^th order is VERY interesting even that I do not know about the filter ringing consequences with such a step slop …
