As I was reading about Dirac ART (né Dirac Unison) I really liked the idea to use the surround speakers to support the fronts for the bass (in case they go sufficiently low)
If I had to take a guess ART will not be available for PC anytime soon so I took a stab at trying to mimic it with the tools I am familiar with
All in all I think I succeeded so I thought I would share my experience here so those who have a 'compatible' system can enjoy this until (or if) ART is released for PC
I have a 4.0 system (pictures here) and my rears can go down to 25Hz - unfortunately in the current room setup they go only to 40Hz (more about that here) but that is sufficient for the purpose of filling in the dips caused by the L+R summation cancellations
Here is how my fronts' L+R summation looks like
(MLP measurement, 75dB, 265cm, used Dirac Live 3.5 for the per channel optimization and GrandEQ for further shelves)
My goal was to do something with that nasty dip between 50-60Hz
Here is how the L+R summation of my rear speakers look like:
They also have a dip there but let's see what we will get anyway....
Here is what I have done:
- set up Dirac Live 3.5 in Stereo mode
- created filters post-Dirac in the signal chain to copy the front channels to the rear channels and applied a low-pass filter at 100Hz for the rear channels
- measured the system with Dirac
This way when measuring L and R channels the rear L and R channels were active too but only between 40 and <100Hz
This is how the end result looks like:
(highlighted compared to the original LR summation)
It is not a huge improvement but it is definitely an audible improvement and I must say that it actually sounds great!!
(not just the measurement but also listening to it)
I have gone one step further and time and gain aligned the rear channels to the fronts and re-did all the above steps
Now this is what I got:
(highlighted vs the original)
Now this looks even better but actually when listening to it I tend to prefer the previous version (strangely enough)
So again I believe that this is something worth trying, I love the sound of it and I would encourage those who have a compatible system to give it a go.

Any questions/comments are welcome and eagerly waiting for ART to be released for PC!
