Impact of passive room treatment and speaker positioning

After careful speaker placement and listening along with advice from Mike at GIK on what passive treatments to implement you can see the results. The test tone is 20-200hz and I also shot 20-20khz which looks very similar. There is zero active correction and measurements are taken from my center seat at ear height using REW, 11.5 ft away from the speaker baffles.

The room being oriented so that I have over 18ft wide open behind my head or in this case the Mic made a material difference.

I no longer have the REW shots from when I started but I can tell you that it was a rollercoaster of peaks and suck outs. So while above isnt ruler flat… I will take it and am very pleased with the GIK products and advice.

Room treatment is always a better option compared to active DSP.  I'm glad you're getting good results.

Yes Mike is great! Also super responsive.

In about 6 weeks or so we will test the impact of open baffle speakers in this room against the baseline curve. Should be an interesting experiment.

What's the size of the room?

How does the FR look like if you set each vertical division to be 5dB instead of 20dB?

The room is 18x30x8.5

If I narrow the DB is range is +/- around 5db except for the remaining room modes. That is about as close as I expect to get until I move to open baffle which I assume will pressurize the room less. Not an expert in acoustic  :)

+-5dB is quite good but the more interesting graph is the waterfall.
