Room treatments

[completeluxury]

So i was playing around with some speaker positioning tonight.

i was only testing low frequencies at this point.

The first photo i attach was my first test. ive now set my 2 subs to mono instead of left and right. in this test for some reason the left sub was still left channel only and not mono and you can see the result.



The second one was after i fixed the config file. you can see there is now a good continuity in the lower frequencies



After that i switched my speakers and subs around - the speakers were in front of the projector screen :/



and then i took measurements again.

The lower frequencies 40 - 80 are still ok, but the 100 - 400 range seem to suffer a bit from the move. unfortunately theres nothing i can do about that - damn screen.



Now ive chosen very specific spots for my subwoofers. i used the calculator from this page and followed the guide:

It calculates at what frequency the room modes are at in your room from the dimensions of your room (every single one of us has room modes) and from that you can figure out speaker placement to beat those modes.

compared to the bass response i used to get in my old room (unmeasured sub positions) this is a LOT smoother. the only frequency i cant contain is that big 20hz peak.
