Hello

Few months ago, i submitted a ''Free Room Analysis'' form and i never got a reply. I've even sent emails to ask why it was not submitted but i got no answer. Anyway, i understand it is free and there is nothing to complain s about since you do not owe anyone anything. But i am trying to get some details about my room in order to improve my studio. So, i decided to post two images of my studio just to see how it looks like.

As you can see i treated my room fairly just to kill some first reflections and indeed it improved a sound a lot ( now i can hear the sound directly coming from speakers ). But i knew at very start that is not good enough since i have been to many professional studios and i know how good it can sound when you put and money into it. But most important element of my room i do not know to even start treating it and that is monitor placement according to room. I know there is sweet spot in room where room modes will take least effect and from there you start your all other treatment (you probably know what i am talking about).

After figuring out that, i want to invest in DIY plans for those diaphragmatic bass traps on your website and after that some diffusers that will sweeten out everything. So if you could help me out somehow or should i submit that again ?

My room dimensions are : 4,70 M LENGHT , 3,05-,310 M WIDHT and 2,65-2,70 m HEIGHT (dimensions vary from wall to wall a bit and as you can see it is kinda hard to measure in cm). Thanks in advance

Hi Liggy, Your room needs large amounts of low frequency absorption . The technology you have in the room is for middle and high frequency absorption . You will need to purchase or build diaphragmatic absorption since it is the only technology that has the horsepower to deal with your room size and volume issues.

I am ware of that. I just need to find the proper placement for my speakers so i have minimum problems to start regarding the room modes. After that i want to buy your plans to build the diaphragmatic absorbers for the studio.

My room is 4,7m on that axis, so 18 " is not good for me (or metric 5,48 m). Here is simple drawing of my room (png drawing) :

So should i maybe half those 18 feet to 9 feet so it is still in phase and i will get 2,7 meters. Btw later when i wrote the post, i have read that moving to 38% of your longest wall will work best. That is 2,8m which is really close to those 9 feet (2,7m which is 10 cm apart). And once i put them there where could i place the bass traps and also the diffusers so i get best results from the speaker area. And what diffuser prime number in your DIY product would do best in my room.

Thanks

Hi Liggy, You need to move your speakers farther away from the front wall. Use trial and error method to obtain smoothest response. Use a P-13 diffuser for your rear wall.

Hi Dennis.

I understand wrongly about moving my speakers. I thought you said feet but you said inches is that correct ? 18 inches which equal to 1.5 feet thus 45 cm from front wall, is that correct ?

But what about 1/3 'rule of the room ? Should i place monitors about 156,157 CM from front wall (about 5 feet). Also. that is true, my listening position and sweet spoot should be around 10 feet or about 3,10 meters ? Which leaves enough space for QRD P13 to barely work... in other words lowest frequency (280 hz) wavelength of the p-13 diffuser is 1,20 meters or 4 feet. Add 50 % which 6 feet or 180 and i am off 30 cm or 1 feet.Am i correct and i did not quite get it ?

Also, i posted new topic which deals with Home Cinema setup. You said to write email to make make package/solution for DIY build plans , i want to this mixing room included.
