Multimedia production home studio

Hi all, My name is Tomislav Rupic and i am from Croatia. I am music producer for the last 8 years and for the last 4 years i am working as video editor. First I would like to say how lucky i am to find this great forum and i would like to thank you all for you effort on making it as it is. Well, I finaly finished my new house and i would like to make small studio in one of the rooms. After lots off reading i finaly came up with some designs, but i am little bit afraid will i do the right thing. Soffits will be made on Johns design, Slot resonators will be calculated after i mesure freq response. Clauds will be hanging on the roof. I will put some absorbes on back but i still dont know what and how. Some other details: Walls are concrete blocks, floating floor (badly made) aluminium window (double glass), doors are acousticly treated(-36db). So my qestions for secund desing are: 1. Am I doing something wrong, is this design ok? 2. For now I am using Alesis M1 Mk2 active monitors. Will they be to far from one another (d-2m or 6.5 foot) ...I am planing to buy dynaudio bm15 or Genelec in future and place them in soffits, but for now should i place alesis in soffints or on stands. 3. What else can i do to get flat sound? Thanks in advance and sorry for my bad English. Best Regards, Tomislav Update: Room Dimensions Lenght: 11.8' Widht: 12.1' Hight: 8.5'

...floating floor (badly made)...

Would you talk on this more, maybe a picture?

For now room is empty, only desk and soffa and whan i walk over the corners it makes sound and is very flexible. I just afraid it will colour the bas sound. Is it posible? One more thing, isolation is not problem, i live in house and my neighbourhood is ok.

Here are some measurements i did yesterday. Mic used is Sony ECM-55B and has freq. response from 40Hz-20kHz and is not calibrated.
