I can say that i am pretty happy with how my treatment turned out. Started to really clearly listen the sub on my Gelenec 8030a.
Today I went with a C0 # Bassline and I saw (2 way pun hehe) a little more ringing. Than the neighboring notes.
So I played around with EQ and tried to get the sound pumping as it should (best to my hearing). But I would say that with EQ I got it maybe 40% 50%. The decay time is still there...
I would ask how much depth in a absorber are we looking here in order to effectively absorb 35hz?
I know about the 1/4 rule, so if we say that the length of 35hz is 9.64.m
So that means that I need at least a 2.41m of porous absorption in order to catch it?
I already have bass traps that are 3.27m high from top to bottom, but seems like I need more. Or the Hight does not affect Length modes? I am pretty sure it does.
Also the standing wave of 35hz is strongest in the middle on the Z axis.(Length) Which means this is the first mode of the room length, that is 4.82 m (Room)
Would straddles in all corners be the best thing to do, or other placement on traps may be better? I also know about helmholtz tubes, But also know they are very delicate. And would require a lot of precise work to execute. If anyone has a good thread about diy helmholtz would be nice...
Thanks on your time,
Milan
