Any advices for my studio, posting REW measurements.

[pyc]

Hello everyone... I'm posting these REW measurements of L+R, L and R speakers. Pretty fresh when it comes to acoustics, can anyone get some conclusions from these measurements and give some advice? So far I think the only thing I can do for taming the 1st axial room mode at 30 Hz is some active (or passive) bass trapping or Helmholz resonator box? That general drop after 300 Hz up until 3 KHz also bothers me a bit, many people say it's the desk, but I don't think so, I've tried putting some absorption on the desk and it doesn't help. At PM request, I'm sending the video of the room...

Just simply use REW to calculate the required EQ to flatten the response as the first step

Here is what your L+R response will look like when EQ-d to flat using a target of 80dB

Been trying to use REW's EQ option the other day, but it seems a bit complicated to me. Anyways, I guess frequencies above 200 Hz better be solved with Sonarworks Sound ID, because some say room modes and SBIR cannot be fixed with EQ, and room mode is the biggest problem at 30 Hz here....?

You have a peak at around 30Hz:

Peaks can and shall be treated with EQ

It is the dips that you shall not correct with EQ (although personally I have done that several times and there are situations when it actually does work fine)

I measured Sonarworks profile now and yes it reduced it around 40 for 3 dB, so I guess you are right. Thank you!

You are welcome!
Just one more tip: Sonarworks is not really doing a great job with fixing the low-end (I know since I have tried it too)
Try Dirac Live (the first 14 days are free of charge) - the difference versus Sonarworks will be night and day
