Hello,
I have a 2.1 setup on the "big" SHD with 4 outs and two questions for the experts here.
1. The distance from the listening position to the satellites is 3m, to the subwoofer 4m.
Should I delay the satellites by 2.9ms in the miniDSP setup or is it better that DIRAC take over this job?
2.The manual said to use a 24dB/octave Butterworth filter for the crossover, elsewhere I found information to use Linkwitz-Riley filters*.
Which filter would you prefer?
Thank you for your support ​

1. Dirac Live has no way to calculate or apply delays and going by distance is very inaccurate - particularly if either your speakers or sub has digital crossover / processing of their own. Your best bet is to use REW measurements to determine the delay for yourself. 
2. I use 48 dB/octave LR filters myself. The steeper roll-off minimises overlap and makes higher crossover frequencies more viable.
