Hi,
so I've started doing some first REW measurements of the equipment in my livingroom and as I already noticed subjectively I'm having some serious dips in the response. My sub is an SVS PC Ultra 13, my main front speakers are Quadral Aurum 9. Crossover is at 100 hz (yes, I know that's rather high but my receiver has a fixed crossover, so I can't do much about that for the moment). The SVS is tuned at 20 hz (no ports blocked), room comp is set to bypass.
Here's a graph of the response of the sub + mains at the listening position.
You can see the rather big dip a bit past 30 hz and also one a bit past 40 hz.
I also measured the response with the front speakers settings at 'large', so effectively with the subwoofer turned off, for comparison.
Then I did a measurement somewhere else in the room, actually where my kitchen is (which is an open kitchen in the livingroom). Here instead of a big dip you will notice a big peak.
Just for fun, I also did a measurement with the meter very close to the subwoofer, which looked like this
And finally here are all graphs combined
To give you an idea about my livingroom, here's a floorplan of it:
All dimensions are in centimeters, green and red boxes are sofas, the middle of the red one is the main listening spot, so the front speakers are the two black boxes you notice in front of the left wall. The SVS is located in the lower-left corner, so that's left-behind the left front speaker. Half of my livingroom has a diagonal ceiling. This is what my house looks like from the side:
So now I don't have any equalization equipment yet and I haven't touch the built-in eq from the svs yet, but I'm wondering if any of that is going to improve the response shown above. I also tried to relocate the SVS to several places in my room but none really gave any more satisfactory results than the place where it's now. Any thoughts on all this?
Thanks,
Jeroen
