Hi everyone - I searched flex eight FIR and nothing of value turned up ;

I have finished my 3 way stereo speakers with flex eight and I'm very happy (after a DSP FAIL! hiccup that I thought had killed the unit). However;

Does anyone know when the section 10 - FIR crossover section of the minidsp Stereo 3/4 way Xover page will be updated, or can anyone advise me what settings I should be putting into rephase for a 2.4khz LR24 crossover phase linearization? 

for example - am I doing this right ? (based on what info I could pluck from the other miniDSP app note on RePhase?)




As this section of the app note is missing/incomplete ;10. Phase correction (optional) [Top] If you are running the standard Flex Eight, you can optionally perform phase correction using the FIR blocks on the input channels. This is described in this app note:
  • Active speaker phase correction with the miniDSP Flex Eight (in preparation)

Thanks for viewing and any help!

Unfortunately not an answer to your question, but I'm wondering how you resolved the DSP FAIL! issue? My Flex is showing it after I tried changing some PEQ settings and I've been unable to get it working.

Thanks!

Reset button on back for 10 sec did it for me - changed from dsp FAIL to dsp OFF and then was able to connect usb to it, open in in Device Console and refresh firmware and refresh DSP

You are doing it correct. Attached is an ideal textbook response from 2K4 LR24 filter, note the phase wrap at 2K4.

Then the second attachment shows the linearized phase when using the phase linearization.

NOTE: you need to have measurements of your loudspeaker, to be able to see the actual system phase (and the SPL).  It is a guesswork without it.

I'm not sure what there is to update.  Your rePhase setup looks correct.
I just loaded that into my Flex 8 and it works fine.
