@abdo123 just found your post where you said you recommend 95hz cover, do you still think that ?


Would you mind sharing some project file for VituixCAD so that I can try to play with the different HP/LP filters and xover freq ? Or maybe I should just try all available on the minidsp and measure + listen...

that recommendation is with the port sealed.

I didn't mention it in my OP but i did seal them using the provided foam, as my speakers are currently close to a wall and high passed

I have been experimenting with a 95hz crossover (sealed), BW 12 dB/Oct for the high pass and LR 24 dB/Oct for the low pass. If I'm not mistaken this should only require 2 biquads for the BW filter. I did this through the minidsp GUI, but i would prefer to use biquads instead so that I can use the 6 remaining biquads of the xover block.

How can I define a 2nd order BW in the REW EQ filter UI ? Is it an HPQ with 0,707 Q ?

"LPQ and HPQ filter types can be used to implement higher order filters as cascades of biquad filters. Here are the Q values for some common crossover types and orders, for odd orders the last section is LP1/HP1 (a first order section), those are highlighted in blue:"

3Butterworth1.000LP1/HP1
4Butterworth1.3070.541
5Butterworth1.6180.618LP1/HP1
6Butterworth1.9320.7070.518

EDIT: confirmed the above, that allowed me to insert the 550 Hz filter into the xover block, and i still have 6 available BQ if needed
