Hi Uli,

in case of a driver amplitude pre-linearization can this be done as usual, just taking the above XO including the reversed allpass or should the amplitude linearization be done BEFORE generating the allpass for phase correction?

Thank you!

Best regards,

Thanks for sharing this video!

Latest official update for acourate was in July 21 to version V1.10.4

... Hope this function will come soon and also the anouncment by Uli.

Best regards,

One question, why is it such an effort to get distortion results with AC? Couldn´t all necessary graphs be stored directly in according working directory and you just have to push a bottom to get distortion measurement result such as in REW or other programs? I really find me avoiding to use this fu...

Hi Phillip, so what exactly is it you do not want to correct above 500Hz? Reducing gain and adding a dip is also a correction and can easily be done by the target curve designer. If you want a smoother correction choose a a small value for the second value (heights) in Macro 1 and/or for excess phas...

Hello, I just want to say a big thank you to Uli for this pleasure giving piece of software and the community around Acourate & Co. Today I received my AIMOS USB Volume controller as Uli suggested here at beginning of this thread and it is a great pleasure to listen to my music now. Volume control v...

Hi, I will check it. But if this is the way to go, than why does a perfect time match of both pulses not do the job as well as it does in theory with both XO pulses? :roll: I have a DBA (front mains with subs and rear subs on the wall) and if I time-align the well adjusted DBA subs with the main sat...

Hi,

can anybody please explain to me, why it is a good target to get a different phase relation between both speakers in transition than in stady stade area?

Thanks!

Hi Uli, I would have expected that, but frankly I am not able to interprete the phase graphics of a linear phase filter. It is just jumping up and down and I see some difference between the lin phase XO and the min phase XO convolved with the reversed excess phase of the sum where the phase is more ...

Hi Uli,

Thank you very much. It works now! Do you see a benefit in terms of pre-ringing compared to a LR4 lin phase XO solution?

Thanks a lot!

Best regards,

Hello, I read below description of Grimm Audio about their crossover and driver linearization philosophy: http://grimmaudio.de/site/assets/files/1088/speakers.pdf They use a LR4 minimum phase filter for XO, do time alignment and do excess phase correction with a FIR filter. They say the phase correc...
