If there is phase offset, the intersect is at a higher level because the outputs add less than perfect.

When the transfer function are in phase (0° phase offset between ways, like in a Linkwitz-Riley) then they are 6dB down at the intersect, both drivers supply one half of the output, their outputs add directly (scalar addition). But this is a one-dimensional effect and can be corrected by applying an overall phase correction to give a linear phase response. The higher the order the stronger the phase shifts and corresponding smearing of the transient response. This is not to be confused with the typically non-zero phase response of the total (summed) transfer function which adds another kind of 'ringing'. There is no way to correct this electrically. Not very useful, for a variety of reasons.Ī proper crossover is designed to sum to flat frequency response and the ringing of the ways fully cancel at least on-axis, off-axis the cancelling isn't perfect mainly because of the time-of-flight differences. Any phase offset (except a straight 180°) is possible but beyond 120° the addition is destructive, each way supplies more that the sum. For a 90° offset (as seen with eg a Butterworth crossover) each way supplies 0.72x of the output (vector addition).

I rarely choose more than 48db/oct after testing. Quick changing filter settings while listening to varied music is my solution. You can fool yourself into 'knowing' you are making improvements, but maybe you are getting further away from your goal. It is easy to 'shrug it off', 'just my imagination playing tricks'. I need more testing to get the filters right, just choosing a frequency and setting the steepest filters does not always give optimal results. If you do not have these problems then good for you.

It sort of changes in 'speed and pitch', do not know how to describe it. What it sounds like is heavily dependent of the frequency the filter works on. After some days/weeks I try to go back to my old settings with the 'slow' filters just to laugh at my vast improvement, notice this really weird effect on my subs first, after switching back and forth, thinking 'they are not supposed to sound like this?', after noticing it there and identifying the problem, I found the same problem present in my other filters as well. I had no clue, just messing around trying steep filters because it was 'all the rage', experimenting. You have to hear bad ringing in order to properly identify it. Just mentioning that steep slopes are not always the best answer. And am very familiar with the pro-steep filters arguments you use.
