Hey mahdes. I just want to let you know that I looked at this. As anomalous as that mega peak at 35Hz is, your real issue is the null at 72Hz. It's almost noon which means I'm about to turn into a pumpkin due to exhaustion so I can't fully analyze this now but the bottom line is that this is more than likely caused by an interaction between your room's modes and the point at which you took this measurement. (I think that's the longest sentence I've ever written which proves the point.) If you haven't, experiment with taking a few more measurements in about a 1 foot radius - or whatever that is in metric - and see how your response changes. It's way easier to find a slightly better listening position than it is to move panels around. Please let me know how that goes and remember not to use any smoothing for your bass SPL. I know some is ok but I'd rather see none. Thanks. Hi Hexspa. THANK YOU ! Is this better? There are no huge nulls and no huge peaks (except around 128hz)so it looks more smooth but whole low end is quiter. I moved my speakers 63 cm from the window/front wall. Put them 97 cm apart - 100 cm from the side walls and put my sitting position cca 180 cm from the front wall/window Is it ok to have monitors so far front the front wall? Everywhere I see- as close as possible but maybe small room and plastic window instead of wall is different ? I found that sitting 180 from the window is the best so If I set monitors as close as possible to the front wall They have to be in the corners to be in a correct triangle with my listening position. Do you think reversing my position-make a window a back wall and normal wall as a front wall is a good idea ? It is a lot of work to do so If it doesn't make a sense, It is good to skip it ROOM SIZE: 470 long 263 h 340 w Attachments:

..is it possible that I have different results with SonarWorks? It looks like everything below 100 hz is 6-7 db quieter - not very optimistic thing to look at Attachments:

Yes, those graph are not useful. mahdes, see this article that shows the best way to scale REW graphs: Room Measuring PrimerHi Ethan! Here is spl 20-200 - 1st picture: I tried as close as possible approach but I had strange dips in the low end (70hz). 2nd picture: I moved my speakers 63 cm from the window/front wall. Put them 97 cm apart - 100 cm from the side walls and put my sitting position cca 180 cm from the front wall/window There are no huge nulls and no huge peaks (except around 128hz) so it looks more smooth but whole low end is quieter.

It looks like that peak is caused by a combination of your 470cm and 263cm dimensions. It's nothing to worry about - just put more treatment on those walls. I have no idea about the SonarWorks measurement.

I have no idea about the SonarWorks measurement. Hi Hexpa. Is it possible that I have best bass response in themiddle of the room? Exactly between front and the rear wall. I didnt measure yet but I compared how tracks sounds on Sennheiser HD 650 vs Monitors and in the middle it was closest. Everything else was somehow....thin.

Usually there's not a lot of bass in the middle of the room. But it always vary, where you have your speakers etc. Take a measurement from that spot where you thought it sounded best! You can post graphs here, or even better the REW .mdat file.

I guess anything is possible. We don't know all the details of your room including construction, etc. At least for acoustics, I don't rely on my ears alone. Try to find corroboration between your subjective experience and measured data for the most reliable result.

Mahdes, I want to use your room as an example of how positioning impacts a room's response. Let me know if you'd like to help out by being included. Thanks.

Sweet. Let me know if you have any social media or anything you'd like me to include. Should be up in a week or two.
