First of all, I am not a mixing expert but a composer so sorry for my poor acoustical knowledge. Also sorry for my bad english. I will be working on a project out of main studio where I usually mix. The mixing room (actually a living room) is awfull...naked walls, big window (door for balcony), wierd dimensions (3.6x7.4x2.5m) with a big opening behind in other smaller room... The worst thing is that I have only one option where to set my little studio - in the corner! All other places are already occupied with other stuff. I do not want to treat the room acoustically to much because it is only a temporary solution. After a lot of experiments with speaker placement I actually found a very good setup (see picture) which sounds really good with mid/high frequencies (lets say above 300 Hz) and imaging is also very good. The only problem that I still have to solve are bass frequencies. I have some cancellations in the middle of the room and also some massive bass waves in the corners and by the walls. The bad part is that I have only one corner in the room where I can apply some bass treatment - the corner where I mix. My monitors (genelec 1030a) do not reproduce bass below 55Hz so I suppose that frequencies below are not the problem. What is the best way to bass trap frequencies from 55-300 Hz in my situation? Also, my right speaker is by the wall which I share with neighbour. I will not listen at loud levels (mostly because of bad room acoustic) but from my experience, low frequencies form this speaker will leak thru the wall and I would also like to solve this problem with bass trap. I would prefer cheaper and simpler sollutions if it is possible because this situation is only temporary but if more expensive soultions offer much better results I am prepared to invest. Thanks!
