In miniDSP Plugin, I have the Main Speakers High Passed at 45hz and the Subs Low Passed at 45hz. The miniDSP manual says to remove any crossovers and run the Main Speakers and Subwoofers full range, and then crossover afterwards if needed. 

I ran Dirac Live with the Subwoofers and Main Speakers crossed over as mentioned above, and everything sounds great, but I do have a couple nasty narrow dips, (I believe 50hz and 60hz), that I believe is not a room mode thing based on previous measurements never having this. Is this because of my failure to run everything full range before running Dirac? Just looking to see if anyone can let me know if I am understanding the manual correctly and I should run everything full range, or if what I did works. Also curious why this is how it should be done? My goal was to allow my main speakers to play down to their max range which is 40hz before they begin to taper.

(My plan is to run this again when I get home to test it out but I am also looking for advice before hand).

PS I love my new SHD Full I/O!!

Thanks everyone!

Hi,
You probably want to do some integration of the subs either manually or using MSO before running Dirac. Geddes approach to sub integration involves leaving the mains rull range without filters and he allows for a good overlap of frequencies with the subs. Have you got the subs away from the mains? The idea is to have the sub bass coming from as many different areas in the room as possible. Lots of videos on you tube to follow and some tutorials on this site. 

 

Hey thanks for the reply, yea I think I just need to try that, run Full Range on the Mains and maybe Cross the Subs a bit higher before Dirac. I will need to check out who Geddes is, I am not entirely new to measuring but am completely new to Dirac. I also do not know what MSO is, I will google it. 

My subs are set up to the insides of the main on the front wall, the gear is in the middle. It is a small space, I only have one corner option and though about putting one Sub there, (to the back left of the listening position), and keeping the other one on the front wall, but in my mind I was not sure how Dirac deals with that? How does Dirac know if I run 2 mono subs in random spots or should I not worry about it and Dirac will perform its magic?

The current measurement has me flat to about 15hz, and taper down from there, what I do not understand is there is no room energization but the measurement looks good? Other than of course that dip I talked about earlier.

My subs are to the right of the front right speaker and to the back left of my listening position/sofa. MSO will determine delays, filters, gains. 

Once integrated Dirac really doesn't care. It send a left signal and hears your left plus both mono subs. And sends a right signal and hears right speaker and both mono subs. It doesn't even know or care that you have subs.
