Hello friends,
First of all, this is my first post in this great community, so treat me with love.

I have started, so to speak, in this world of looking for good sound, I have gotten a couple of equipment to get started, I have some JBL Stage A130, Ampli Fosi Audio BT20A Pro, an IFI Micro iDSD Black Dac. I have liked the result so far in my understanding of all this. Having said my introduction, of course I accept advice that I could add to the line.

Today I come to ask you something that no matter how much I have wanted to learn, I cannot know everything,
This week I decided to read about room treatment and measurements. Influenced by the guy we all already know, I downloaded REW and started making my measurements with a microphone that luckily I had saved somewhere,

This was the result, and I would like to help me interpret it, tell me if in general terms I have good sound in my 3x2.5 room;

It will be easier to give advice if you set the upper/lower bounds of the chart 50dB apart.

However, I already see some issues, you have a 10dB drop from 50hz to 100hz, a huge peak at 200hz, and some smaller peaks here and there. These could all be fixed with some pretty simple EQ.

Maybe zoom in a little bit? I can see dips at 40dB and peaks at 90dB (especially above 6khz)
hello All Friends

I attached some images a little closer

Your comments on how to improve will be welcome.

So I assume you have heard that you should use EQ to correct this response...

Looks like you have a peak at 50hz and 200hz for starters. You should hear some improvement if you can use PEQ to lower those peaks. REW has a function to generate those parameters for you. You can use EQAPO on a PC to apply the EQ, or a MiniDSP unit, or even a WiiM unit to apply the EQ otherwise.

I am not sure which microphone you are using, so I will avoid commenting on the response above there.

Where was the microphone when you took these measurements?

It might also help if you apply a little smoothing to the graph, it can make it easier to read.
