Last time I looked at REW for it's room simulator (think it was REW), I concluded that the simple room layout in the simulation did not equate to my room. My room is rectangular, but then imagine a recess on the back wall where I have a dining table, so not an L-shaped room, but a little like that. I also have recessed windows in deep thick walls on the front wall, so they're like a couple of deep boxes (with angled sides ) recessed into the wall behind the speakers. I think I remember concluding that the simulator didn't let me put in all the variables for the room size/shape & speaker placement. Let me know if I'm wrong in how I remember this, and I'll give it another go.Thanks for sharing your experiments, Robbo99999 !
I depends. I do my room eq up to 600 Hz.
It would be interesting to know if the strong variations between 100 and 200 Hz in your frequency response are physically caused on the speaker side or on the listener side.
The room simulator of REW can help you find this.
For me, the main variable is the target curve, rather than the smoothing. The success of my room eq strongly depends on slight differences between targets.
For the variations I see between 100-200Hz are you suggesting that there's a defect in my speakers? I looked back over some historical room EQ's & measurements with different room layouts, as I changed my room layout & speaker position a little since I had these speakers, and the peaks & troughs are not always in the same position which leads me to think that it's not the speakers, but the room. I'll attach my current and a few historical ones here:
The around 30-50Hz peak is always there along with it's dip afterwards. The dip between 100-200Hz changes position with layout by the looks of it.
Yes, given your graphs at all your listening positions then I can see how roomEQ would help all of them, because there's the common peak between 40-60Hz for instance.I know that this is uncommon, but I am in the opposite situation : the room eq makes the sound much better all around the room (and even in the next rooms).
My situation is simple, without any eq, my system makes the noise of an elephant's herd. With eq, the elephants are gone.
I measured a set of frequency responses in various positions in the room. All measurements are single point sweeps, and therefore look quite jagged, compared to a proper MMM or multipoint measurement.
The red dot is the sweet spot. The blue dots are extra measurement positions.

In each of the following pictures, there is one measurement with room eq OFF, and one with room eq ON. The one with room eq OFF is always the one with strong peaks in low frequencies.
The room EQ is exactly the same in all graphs.
