CK.

Thanks for sharing. I found that AP with Q<1 is not surgical enough and affects a broad range of feequencies and sometimes you end up...

I played with this in my Flex HTx setup. OCA’s 0.707 / 0.577 were great starting points, in my room the broad issue around 44 Hz...

With IRR you will have no pre-ringing so sky is the limit but you would be adding more and more group delay :) Actually, REW default...

In case of using IIR all-pass filters, what max Q would you recommend?

You can use as many IIR allpass filters as you wish using biquads in miniDSP (can be designed in REW EQ) but they will all probably...

These are some good options I haven't thought about, cheers.

For what you are doing, it can be sufficient to eyeball it in rephase as you don't need ultimate precision to produce good enough...

*note thought that's it's not really free if you want to export filters for actual use and not just simulation.

hm Ok thanks let me look into this.

You could also try LinFIR if you use Windows. *I know with rePhase, you have to go back and forth exporting and importing IRs with REW...

yes I was thinking along these lines of a mixed phase filter, but you make it sound like this is a bad idea :) Sure the phase distortion...

if you really really really want to try using FIR manually then I'd suggest to use rephase and it's paragraphic eq to draw the response...

Yes but an all pass filter has a fixed phase rotation, I was looking for variable FIR all-pass filter (rephase). but I was not able to...

Yes I was thinking of using rephase for a couple of phase EQs (minding the pre-ringing), but in rephase I cannot properly design the...

The delays in the miniDSP have been adjusted so that the mains with sub are time aligned (based on the step responce) and the phase...
