Post Subject: Near 90 degrees slopePosted by Romy the Cat on: 8/5/2013

The more I think about it the more I realized that this 120dB per octave crossover is very interesting move. For sure it is bold move. There are unquestionable benefits of such a “barbaric” crossover as the throwing way bits at the signal get attenuated has virtual no room to be heard. Also, there is no lobbing of multiple sources of any kind, neither the comb filtration distortions. So, hypothetically if you have 6 channels, run only digital and have 6x120dB per octave crossovers build into 6 identical DACs then you do cover all grounds and it is possible that in THIS application digital crossovering would not be as bad as it uselessly is. Still, I have absolutely no idea how two drivers located at tow different axes and separated by 120dB per octave crossovers would sound. I in my practice so much accustom to recognize an individual channel is not an individual channel but rather a combination of this channel with two neighboring channel that I am a bit at lost to forecast how 120dB per octave channel would sound. I do know that this 90 degrees slope does not exist in nature and most likely crate some kind of phase big dang but I would not guess anything else.
