stationary measurement of my setup, any clues how to EQ?

[olds1959special]

My current bedroom setup has got the 12" sub on the bottom playing 45 Hz and below using a 12 dB Bessel filter. The remaining highs are sent to the middle sub and top speaker also using a 12dB Bessel filter. Then there's a hardware crossover between the middle sub and top speaker set at around 100 Hz.

The gain is maxed on the bottom subs and top speakers while the gain is lower on the middle subs. I came to the crossover settings and gain settings through experimentation. I picked what gave me the flattest measurements.

I prefer stationary measurements because I sit in one place at my desk most of the time. I used my MM-1 mic with 0 degree cal file into an ISA One pre-amp with medium input impedance (2.4kohms).

I'm curious if there are any specific EQ settings that may be helpful, or any other setup advice if anyone has any. Reduce peaks at 45, 120, and 440 Hz maybe?

I do think the no-EQ measure is a very good starting place, given what I assume is a small room.

I am sure someone will ask for you to zip your measurement files and upload those, so consider that asked.

I only use 0 degree cal for things like driver measurements, or seeking out specific resonance locations in the room. I use 90 for the whole system playing in the room. I am pretty sure the advice here will be use 90. Someone might even give you reasons for that!

I also typically use 1/6 for eq, occasionally 1/12. That makes it much easier for me to see the bigger problems, and ignore minor ones. And I usually burn up my 10 PEQs at 1/6, so why bother with less smoothing?

If you provide the EQ settings you used, people can comment on your approach.

But I do think you have very good set up and start, and that the advice you get from people with more knowledge than I (most here) will help you get where you want.

It's a pretty small room (maybe 8 ft x 12 x 10 ft?) but the back "wall" is sliding wood doors which are semi-open and so not a full wall, and the speakers are at the opposite wall, facing into the length of the room. I'll attach the measurement files and try the 90 degree measurement too (mic points up right?). Next time I'll apply the 1/6 smoothing too.

I tried some EQ settings. At first it seemed more "detailed" and "clean" but then I realized it was also anemic and lacking in bass (all I did was cuts to the peaks). I don't think I can trust my home-brew EQ settings yet and like the idea of using my systems without any EQ right now.

It looks pretty good.

Agree with paretto, except you better try the psychoacoustic smoothing from rew to desisgn your eq. The 1/48 octave make things look worse than they really are from a perceptual point of view and won't help to target the right frequencies to eq.

That open back might come in handy, if possible I would have my speakers pointed at the opening. It will cut down reflections from the rear.

Yes, 90 degrees is straight up.

Oboreal makes a good point on psychoacoustic smoothing. I rarely use it, but it will help you not be tempted to over-correct the higher frequencies. I think it's a good place to start when learning.

I changed my setup by running my Apogee Duet 3 balanced direct to the main speakers and then using the miniDSP to output to the subwoofers only (using drift correction on the bass.) There is no EQ applied now. Attached are my measurements.
