Hello everyone.
I would like to know your opinion on the equalization that has resulted from my measurements with REW and if it is correct from a technical point of view.
You can see my speaker system in this forum.
What I have basically done is equalize each speaker separately from more or less 150Hz to 20,000Hz and treat the area below 150Hz as if it were a single low frequency driver, using the joint response of the two 15" drivers measured in REW to equalize.
I use minidsp 4x10HD, and this allows me to link the two channels corresponding to the two bass drivers and equalize them together.
I hope I have explained myself correctly...😉
I leave you some measurements so you can observe the results.
RIGHT SPEAKER. Equalized response from 150Hz to 20,000Hz. Not equalized from 150 Hz to 30Hz
LEFT SPEAKER. Equalized response from 150Hz to 20,000Hz. Not equalized from 150 Hz to 30Hz
L+R response with joint equalization of bass driver.
The measurements are made from the listening point.
Regards.

Your speakers are looking good!
I assume you used measurements without a time gate. That implicitly means that the direct sound and reflected sound is all weighted equally. Our hearing does not work that way. Equalizing in a better way is not trivial. You can read more in this Dirac Live white paper, for example.

It may seem that the equalization I chose in the mid and high ranges produced a sound that was too bright and analytical, but in reality, and for my taste, it is the part that I have no complaints about, and I quickly felt comfortable with it. However, I don't find the sound completely satisfactory in the low range, which is why I wanted to know your opinion.
Greetings.
Often when you find there is an issue in one of the extreme range working on the opposite one can solve the issue.
You should gate an apply some smoothing (1/12 octave to 1/3 octave) to have a better idea of what you should eq imho.
What is your issue with low end? I bet you miss impact in the kick drum, bass ( instrument) should sound a litlle subdued. Isn't one of your low way located at 70cm distance from a wall or reflective surface?

I am really satisfied with the sound at low and medium listening volume. The problem occurs when I raise the listening volume, at which point the sound in the low range becomes somewhat annoying and muffled. According to the frequency response shown in the graphs, there is no peak that could cause excessive problems, but the sound does not convince me.
It is probably a problem associated with the listening room, which does not have special conditioning (it is the living room), but with my question I wanted to be sure that my way of equalizing is adequate, and if it is not, to change the method.

Yes, I have considered it, but sadly I would only be able to place a sub in the back of the room and without freedom of placement.
Maybe at some point I will try it.
Cheers.

Some use a spatial averaging method. I can't tell from your description if you only measured at the listening position (single point) or if you used several physical points around that. Sometimes using a single measurement point leads to equalization that can sound unnatural.
How much boost and cut you applied would be good to know also. Filling in a hole in in-room frequency response sometimes takes more boost than is advisable, which can lead to very high power demands.
I take several measurements around the listening point, a distance of about 30cm around.
Luckily, at that distance, the frequency response does not change much.
