Hello :)

I just saw this video

This room kinda matches the idea for diy project for my room. But i was wondering about Diffuser Bases.

1.I want to build them myself but most likely using the material (‘foam ‘) as instructed in DIY BDA plans, i dont want use carbon. So how you build them ?

2. Also, you mentioned in DIY Diffuser plans you can use MDF or wood, but when i translate types of wood, it dont show the names. So what type of wood can be used for diffusers ?

L, You need to build the bases to support the diffusers and make sure they are the correct height to match usage. Start with bases 24″ off the ground. Use alder, birch, pine, cherry, basswood. Do not use MDF for diffuser . Use wood.

And what i need to do with insides in Diffuser bases ? I know it has carbon filters in the video, but what i can put instead carbon ? And also where to position the filters ? Does it have more less DIY BDA layout without diaphragmatic boards (because what i can see, the Diffusor bases are sealed tight, front panel does not move).

And also what is type of wood is Alder and Basswood ? I could not translate on Google.

And what is difference between MDF and wood for diffuser ? You said in DIY plans you can use MDF but i was curious to know why ? :)

Thanks

L, You can fill the bases with foam or building insulation. Do not pack it in just pressure fit. MDF is too absorptive for diffusers. You can use it for the cabinet itself, but the vertical and horizontal well dividers have to be wood to avoid over absorption ..

I dont understand this part “do not pack, just pressure fit,” Do i stack,let’s say 3,4 inch on rockwool filling, till i end ? In other words, i use X ammount of them i stack them vertically inside cabinet ? Could you elaborate in more details this ? Thanks

L, Fill in the total cabinet volume with material. You will have to determine how many to use and what thickness.

Dennis i only found veneer wood like :

BEECH
OAK
ASH
MAPLE
WALNUT
CHERRY

Cherry is only tree i have on the list that suits the build it is little expensive. I calculated that i need 6-7m2 to be safe + cutting cost. So can i build from others from the list ? I will try to find Alder, birch, pine, cherry, basswood, my cousin knows ”wood’ stores because he is furniture business . Btw, what wood gives best results in terms of building efficiency, Like what wood is most easy to make diffusers from the list (in other words, best to be processed ).

Thanks

L, Stay with softer woods like the Beech or Ash. Pine is also a good option.

Hi Dennis. I start making diffusers in 2,3 weeks but i cant figure out what type of wood to use. I know kind of wood (just like you said) but i cant see from pictures is it : chipboard plywood or something else ? If i chose pine, i have option to use veneered pine board (we call that Shper Ploca or translation Plywood but Plywood means so many thing in english or google translte is wrong).

And please try to use example for each wood. I mean what type wood i would use if i use cheery or Ash for example. For pine i could kinda guess because there is plywood as option (Or shper ploca in my language). If it hard to explain, try to use more detail.

This is shepr ploca ( i think it is made from pine )

https://www.google.rs/search?t…..38;dpr=0.9

And this iverica (or also plywood) but you can take Raw or veneer finish (like cheery, or if you know color Venge)

There are several ways to build like these rooms you can check http://www.acousticbarrierfact…..ier-fence/
you should apply the steps carrefully.

2. there is not a single type of wood to use, a lot of Studios use Reagan or you can read about the one you like more.

L, Build the diffuser bases the same way as the BDA. Just make it shorter at 24″. Use softwoods for diffusers. Pine, alder, bass wood.
