room correction or treatments

kharp1

Not much worse than a bad DAC, IMHO.

so i build 8 sound panels and wanted to mount them in my L shaped room. I have to keep ascetics in mind.
Based on my L shaped room layout and dimensions. I can get 3 on one wall and 2 on the other (see red lines). the purple line is a line of blackout curtains and i build panels to slide into the windows behind it but I cant get any more panels on the wall there. I was thinking of building stands for the remaining 3 and placing them in the opening to the leg of the L. see green lines.
would this be benificial?

Where are the speakers located? I think people will need to know.

i added some room treatments on the left and right wall. i will say the sound stage has never been better. it has expanded way beyond the positioning of the 2 speakers to the left and right. Almost can hear things coming directly parallel from my seating position now.

also have found that recordings make a world of difference. some tracks sound like crap but if I get a different recording of it .. it comes alive.

One thing I have also found is higher volumes make things sound better. Is that just cause of the volume of the room?

You are not getting all those reflections anymore that only serve to make the music sound harsh and grating at higher volumes. Yeah that's a common phenomenon that I have experienced.

Here's some data that I have gathered from my research towards building my own panels so far. The rigid boards are nigh onto unavailable in my area unfortunately, and the shipping costs can be exorbitant.
