Congrats
Compared to my Eris 5 my room mode at 130Hz is much less pronounced by ear. Didn't measure yet. Bass is also moderate. Curious what the measurement will show. Phantom center is very good and they are much faster and more dynamic than the Eris. Even without any room correction they sound good. Was not possible with the Eris.Congrats
How's the sound?
I can't really tell anything from that graph due to the settings used, I don't have REW in front of me now to suggest alternative settings to look at.@fluid suggested to look at the spectrogram to check where the dip at 100 Hz is coming from. Can I learn something from the peak energy time at 100 Hz which is ~50 ms?
It doesn't look bad. Now you need at least one subwoofer and you are doneDid some measurements last week and these are the FR of left (green) and right speaker:
My speakers are ~65 cm from the front wall (front of speaker to wall) and the front wall is treated with 3 GIK panels (~10 cm thick). In the front corners there are 4 Bass Traps and on the ceiling 4 Basotect panels. The rear wall (the room is L=8m x W~4.7 m, H=2.4 m) is untreated. In the FR there are two main issues: Dip at 100 Hz and a broad dip at ~1kHz. I think the 800- 1000 Hz dip comes from comb filter effects from the big table. The 100 Hz dip is unlikely SBIR from the front wall as I have the panels there. It gets better though when I remove the panels and move the speaker close to the front wall (from my experience with my Eris 5 monitors, I'll look for the measurments), but I want to sit close to the speakers. Moving the table closer to the front wall is boosting the 130 Hz mode a lot! If I remove the panels and leave the speakers at ~65 cm front wall distance (like they are now) I get SBIR at ~200 Hz, which is not present with the panels. I also read at gearslutz that a dip at 100 Hz is quite common (even for professional studio) and that treating is not necessarily the best thing, because we are used to have a notch there because of floor bounce. The 800 Hz- 1000 Hz I could treat with some aborbers on the table or playing with the desk filter of the KH120. This will lower the 200-300 Hz range a bit. The measuremts above are without room correction.

you are EQing right? so take boosts (modes) over cancelations (notches).
when I integrated my sub I took 50-ish meassurements moving it around (3d - in a small place).
play around with positions and take the free boost.
look in my graphs in post #52. 75Hz is more boosted in orange, but it is the right choice....I eq it down anyways (and loose no headroom doing so)
That would mean I have to completely move close to the wall with the whole table and (worst case trough my GIK panels out again )
Yes, I'm EQing with drc-fir. (as Sonarworks dropped Linux support again)
I'm a wheelchair driver which complicates things That's why I was looking for lightweight speakers. Maybe I would have chosen the IN-8 otherwise. But maybe it's worth a try to put one panel to the side and make a test with just one speaker.If monitors almost touching frontwall gets rid of the dip, you might not need those panels there anymore and can put them at the back (freestanding). that could get rid of some ringin from the first longitunal mode.
but I din't say you should do it like so, I said you have to play around more with positioning. I know it sucks since moving stuff around is a lot of work, but you can find some nice improvements (for free)

no local audiophile friend or relative? or just call a normal friend and buy him a beer lol
I think the best place for the GIK panels would be the ceiling
