Re: How to build a flat-phase DSP preset?


If i have to make a DSP preset for a 2 or 3 (or more) way loudspeaker i try to get the phase response as flat as possible for several reasons .

The most important 1 for me is that a loudspeaker with a "flat phase" response is easy to combine with other loudspeakers with other loudspeakers with a not so nice phase response by the use of all-pass filters .

Also a flat phase response (and a "semi" flat frequency response) somehowe makes it more easy to listen too for me anyway (i do not know why maybe it's just me) .


If i get a system like this :

I would be pretty happy


This is a 4-way system including subs measured near field and corrected with the use of all-pass filters (do not remember how many but probably 8 or 10 and the sub allignment was done via all-pass filters not delay) as described @ my blog .
