I'm not avoiding anything: i curently use 'high steepness' xover ( over 100db/octave for one of the xover -at 6khz), but can't speak of higher steepness as they are not availlable to me ( in a fair comparison, but it is a bit long to explain here and won't be interesting to most) and i would not see an use for it atm ( for xover duty it could even be argued by some than more than 24db/octave have few real life need - but it can happend Momomo already gave example).
My comment is oriented toward practictal use and choice made in a 'good' hardware 'real time' xover processor ( max latency 25ms which is already too long if there is live event or image involved). Nothing more.
I'm not saying it's a magic bullet or it should be used in place of other technology. Just the preringing if often cited as an issue which in practice isn't to me and other users.

Pre ringing isn't really a issue I've done brick wall filters with 68k taps it didn't really show any excess ringing but if you use fir filters for room correction and go crazy with it you will have ringing.
Wanted to revisit now that the center speakers are built. After carefully observing the impulse response I guessed at the appropriate delay for the tweeter and midrange and adjusted the delay empirically by inverting the midrange and looking for the biggest dip at the crossover frequency. As a result of this, using crossovers at 300Hz and 3,000Hz I have ended up with textbook frequency and off-axis responses. However, what I did not expect is that the tweeter delay is the smallest. That is:
Woofer = 0
and
Midrange delay > tweeter delay.
Is this what is expected or has something gone horirbly wrong?? 😀
