TOPIC:

I purchased a SHD recently and am impressed by the features but am well out of my knowledge base using the room correction. I understand the taking of the measurements (just follow the directions) but I quickly get confused when it gets to filter design. I have a 2.1 setup in an upstairs "bonus room" over the garage. I have my sub hooked up and routed as per the SHD user manual (Left and Right speakers linked, sub on output 3, 80Hz crossover). The attached is the measurement I get. The user manual states that the sub should be a little louder than normal and my first measurement was extremely bass heavy (so much so I only got an auto target curve for the low end). I turned down the volume on my sub and it seemed to help. At this point what should I do next? I am at a complete loss in what this curve is telling me...

Any help educating me is appreciated!

Looks pretty good to me, the software is telling you what it thinks you should do to correct the speakers to get a typical flattish response.

The really jaggy curve is what dirac measured from your speakers.

You drag those points around and get a curve that you like the sound of - i personally like doing about 9+ db from 200hz down, and i like to have it flat otherwise but there is all kinds of curves that people try and you might prefer. You can double click to add a new point.

Look up the NAD curve or the Harmon curve or the Smile curve etc.

You may as well program in 4 curves to try and export those into the 4 preset options to test.

Will Dirac boost up to +9dB?

Yes, if your amp has enough power, it will... but if you have a hole caused by room response it might not be possible as the signal is being cancelled by an echo and you might find the only way to solve the issue is room treatments.

@WerTicus Thanks.
Have you got one of the Smiley curves - Equal loudness curves values as a .txt file.? Any place you have seen them?

It's going to be a matter of personal preference what you like... I would suggest you load in a few curves and just swap around till you settle in.
