I do not think it will help to make some passive bi-amping You have some details for crossover calculation here Crossover: IIR or FIR? (2) (devialetchat.com) As said for 1st order the frequency to apply is the cut off frequency. If you want to use 4th order filter some calculation are needed. Once you choose the right crossover well you can enjoy your active settings. Better impacts, usually less distorsion. Just be carefull to not send the wrong frequence to your HP by messing up your settings. These Devialet amp are incrediblely open to many configuration. From D200 to D440 on JBL 4430 - Waiski - 01-Dec-2021 That calculation is made by my friend who is speaker builder/designer. He has also developed VituixCAD loudspeaker simulator. https://kimmosaunisto.net/ So you can rely that calculation method is correct. He said that Devialet crossover is almost like Bessel but actually is not. He named it as Dessel RE: From D200 to D440 on JBL 4430 - renan - 04-Dec-2021 Well Waiski, You post on the Dessel was very helpful to me. And yes the calculation are correct and give the expected result. Thanks to you and your friend RE: From D200 to D440 on JBL 4430 - Waiski - 04-Dec-2021 (04-Dec-2021, 12:15)renan Wrote: Well Waiski,Devialet Pro's are superb boxes full of excellent features but we need to know how to use these features. When Devialet doesn't tell how things do work, we need to do the research ourselves and help each other |
