RT60 measurement in my room

[Analogous]

Grindstone explain that quite well. Room boundaries start to dominate at low frequency and the microphone can't process reflected sound quite well. If boom and resonance is an issue in your listening position, try sitting in midfield or maybe near field to listen. This would somewhat mitigate most of the room gain issues. You will also benefit from better imaging.

Thanks Hari. Indeed I have been extensively experimenting with both speaker positioning and my listening position too trying to find the optimal sound. As I mentioned earlier I am not able to hear the extra problem resonance at the low frequencies as shown in the RT60 graph. But that’s my problem/puzzle to solve.

Thanks to generous help from @kratu I could finally get the acoustic measurements in my room.
Here is the RT60 graph
ChatGPT points out that I have a problem between 40-100 Hz and need to use large bass traps in the corners.
Any thoughts, opinions and suggestions?

Dev your room is pretty good imo - a lot of the frequencies lie in the sweet spot between 0.3s - 0.4s.

As others have said here, also important to look at the frequency response from both speakers to your listening position.

Tuned bass traps are hard to implement - the waves are so long that one measly bass trap in the corner is hardly going to be a fix what may ultimately be more pleasing is to use an active crossover / eq along with a subwoofer from REL.

Thanks!
The brief agitation over the RT60 curve findings has subsided.
I do have a REL subwoofer but have not tried it out in this set up as I felt it would only emphasise the same problematic frequencies as shown by the graph.
I am not sure if getting a equaliser and setting it up properly with the Subwoofer could make this addition into an active bass trap? How to alter the timings? This would be another steep learning curve involving more measurements etc. I am not sure I want to get into this as music in my room does sound good and very engaging to my ears and mind.
I did find this (expensive) option.

I will research active crossovers as I don’t know anything about this.
