Dirac DLBC + MSO?

[win]

I replaced my dbx venu360 3x6 crossover and minidsp shd studio with a minidsp drc88d and dac8 in my main system. I have use for them elsewhere and thought the upgrade would be nice.

I'd previously used MSO to create PEQ/gain/delay filters for the four subwoofers I have. After integrating this with my mains, I then ran Dirac upstream on the shd studio's 2 stereo channels. This produced very good results.

Now, I have the ability to run Dirac on all 6 channels (2 main + 4 sub). My question is if I should do this after implementing the MSO optimized adjustments first in the 4 sub channels. Would the MSO's adjustments be redundant to whatever Dirac DLBC is going to do? My thought was that getting the subs close to ideal would create a nice baseline from which to run the more sophisticated FIR/IIR/biquad filtering that Dirac uses.

I guess in other words. Is it useful to optimize gain, delay, and PEQ on the subwoofers holistically before allowing Dirac to optimize each channel on its own?

Thank you

In another thread, @staticV3 said that DLBC is an automated version of MSO. I have no idea how DLBC works so I can neither agree nor disagree with his comment. It was my intention to ask him to expand on his statement so hopefully he will see this thread and say a bit more.

Both DLBC and MSO aim to optimize frequency response smoothness across many listening positions by using multiple subwoofers scattered across the room.

You measure each sub from different locations, then the software calculates ideal phase, delay, gain, and frequency response parameters for good Sub integration and low seat-to-seat variation.

ART and Waveform take things a step further by using your subs as active bass traps, to cancel out would-be standing waves and reduce decay times.

From what I understand MSO will generally be able to do a better job if set up properly. While there would be no need to do Dirac after a proper MSO setup, you can always try. Also, possible that with given room and system Dirac will do as good as MSO.

Unless there is a recent massive upgrade I’m unaware of, miniDSP has unfortunately not implemented DLBC in a single one of their products. (I had hoped miniDSP would jump on Dirac’s improvements but they have not. As an aside, I’ll be listing several miniDSP products for sale soon, as I’ve kind of given up on waiting for them to modernize their Dirac support and moved to other gear.) So for bass multiple channels of Dirac will just screw things up. It will try to EQ each sub flat, which is dumb.

Carry on as you did previously.

will minidsp ever implement true Dirac live bass control? It seems like you have to treat all subs as a single unit, which means that the answer to my OP question is that yes, you want to use both, I guess.
