After many years I decided to put some time in the acoustic of my studio, I`m new to acoustic treatment and all I did so far is from what ever I could find and understand from the internet. the Bass Trap help a lot for the low end and I was wandering what else I can do to help my mix/Master translate. So basically take my crapy 12'X 13'X 8' room out of the equation as much as possible. I understand that my Room will never be GREAT !
What I have so far : Room dimension L13 X W12 X H8 with Wood Walls/ceiling and a Large tick 6 X 8 Carpet on the floor
3X Floor to ceiling Bass Trap made with Rockwool on the Front L&R corners and Back left Corner
1X BassTrap, W24 x H48 x D6 made with Rockwool used as in the 4th corner (Door, no space for a full corner BassTrap)
1X W24 x H48 x D6 Ceiling Cloud
1X W24 x H48 x D6 on the left wall at the 1th reflection point
At This moment I have 2 Skyline Diffusor (748Hz X 4526 Hz) on the Back Wall with a 24 X 48 Foam in the middle
I`m looking to Put 3 Absorber of W24 x H48 x D6 made with Rockwool on the Front Wall behind the monitor,
Place 3 W24 x H48 x D3 with 1 Inch Air Gap at the 1th 2th and 3th reflection on both side walls
Place 2 more W24 x H48 x D6 Ceiling Cloud in line with the 2th and 3th Pad.
Place 2 W24 x H48 x D3 with 1 Inch Air Gap at a angle on both wall to ceiling corner of both side wall and 1 also at the angle on the front and Back wall
Replace the 2 Skyline with a Large square Quadratic Diffusor on the Back Wall.
Probably make 2 more and move my Skyline Diffusor (748Hz X 4526 Hz) to my small live room so I can put 1 in eache corner ceilling.
I doing Primary Mixing but sometime Mastering as a last resort
There are various kinds of bass traps. Those made of rock wool are little effective under 100-150Hz. You need a lot of them, with really high density, depth and distance from wall/corners. 3" of wool, 1" distance from the wall isn't really a lot. I got tempted to try those cheap, corner bass traps (4 of them, 1m high, rockwool) and did measurements with REW, before/after. They did very little below 150Hz and starting from 100Hz down there was hardly any change. My room had over 20dB peak at around 100Hz and it has been reduced by no more than 2-3dB.
Personally, I think it sounded a little better than untreated room. It got more clarity in bass, but the main problem was still very present: when playing G# and D on bass synth in low octave, G# was very noticeably louder louder, i'd say "many times" (I mentioned already +20dB @ 100Hz) and it made working with mixes in this room very difficult.
Check blog posts and youtube videos of Denis (or other publishers) to see what options are effective for the low end. And don't be surprised, they aren't small and cheap. You need lot material or advanced technology to effectively control the force of bass sound waves.
