Post Subject: Three mid channels crossovering - playing in the middle.Posted by Romy the Cat on: 9/28/2007

Jessie, in the configurations of the horns and derivers that you are building your mid channels do not exposed too much to stresses. It is not that you have a situation when 1/4 octave more and less will send your channels into suffocation - your horns/drivers operate within a relatively middle and secure ground. You might move them up and down as much as you wish (still within the boundaries of the horns rates), it is all educational but you need to also measurers them to make sure that you still have overall flat response.

I do not see your today finding as something that you will accept as final for yourself. If you decide to go 5-chennal with active amplification with your horns then the character of the MF sound will change.  It will not be “different” but it will be altered and you might review your positions how the best to mix those 3 channels. I am listening now left channel (because the first violins are there) with new 6-channels Milq and the  fully “active” Macondo and I might say that “active” Macondo has own, more advanced, Sound compare to the right channel, still driven by 3-channels Milq.

I somehow feel not comfortable that what I went to line-level crossover I somehow decided to replicate the crossovering patters that I have with speaker-level crossover. Well, I went to 6dB/octave on the Fundamentals’ Channel high-pass but the rest was the same…. It might be worth to experiment and perhaps to altar the crossover points again, but I wish I would have time and desire to do all over it again.

Consequently, what I am trying to say – if you defiantly go for DSETs to each channel then hold your experiments to the times when you will be able to conduct the experiments at line level. Then you will borrow or lease an active multi-channel crossover (digital of analog) for a weekend and will easy mimic all imaginary configurations – very educational  (I did it in a past). Do not forget that in active configuration you have control over harmonics of EACH channel and it will be a big dissimilarity. I very much presume that your findings now and then might be different…
