Dirac 3 with Minidsp SHD: random error in equalizing subwoofer 3 months 2 weeks ago #61093

Hi there,

I have used Minidsp SHD for many years with many different configurations. I am now experiencing a weird issue with my subwoofer. 
When I run the Dirac swipes, all looks normal and I can see the subwoofer in the frequency response.
But after applying the filters, Dirac inexplicably equalises the subwoofer down by several dbs, so that in the finished filter the subwoofer is almost non-existent, about 10db below the mains!
Dirac clearly makes a mistake in calculating the filter for the lower frequencies here, and I have no idea why. Any suggestions?

That sounds rather odd if you're used to using Dirac but I'll ask a question just to rule out a simple explanation. How are you assessing that the result is much lower than intended? Does it sound wrong or are you possibly looking at a single measurement point result in a new setup that is just more different from the spatial average that Dirac Live actually targets than you're used to?

Another thing to check would be that you haven't inadvertently got your signal routing slightly wrong.
