For quite some time I was using minimum phase room EQ filters tha I generated mannually with rePhase, but recently I decided to apply full scale time domain correction and go for linear phase response. As a result I got pretty nice looking phase, GD and step response graphs (measured at LP, 4m away from speakers):
As a side effect I also got some pre-ringing in my filters which is visible in IR:
Left
Right
That pre-ringing visible before IR got me worried a little, especially as I was not able to find any relevant data on the Netabout audibility of pre-ringing artefact. And no, I cannot hear any nasty effects after I adjusted phase - subjectively I would say sound got better, but of course it's impossible to tell that without a proper blind test.
Anyway, what I did found was an IR response of Topping D10 posted on this forum:
What surprised me is how similar it looks to IR of my speakers, both in terms of shape and in terms of pre-ringing. Based on that my conclusion was that pre-ringing with my room EQ filters is very acceptable, so nothing to fear off.
What are your thoughts/comments on this?
