Re: Time alignment of drivers in active multiway speaker systems

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,

Jörn

Re: Optimizing speaker distortion

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...

Re: Room Correction Filter for <500Hz, and Only Gain Reduction above

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...

Re: USB volume control

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...

Re: Transition area vs steady state

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...

Re: Transition area vs steady state

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!

Best regards,

Re: MP crossover phase correction

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 ...

Re: MP crossover phase correction

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,

MP crossover phase correction

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...
