Hi first let me thank everyone here, you have saved me a lot of money, time and aggravation from not buying foam.
I am just about done finishing my drum room 14 - 18 ft and have some questions. On my slat wall I left open space on the bottom and it still has isolation behind it . The idea is undiffused absorption from the kick drum, Is this a good idea?

My corner bass absorbers do I have to go all the way up? I’m trying to use the top as a little shelf.
They are not installed yet just put in place so you can get an idea.
On my slant walls should I leave them reflective, peg board and insulation or absorptive they will be covered in fabric either way with slats in between. With the room size I just don’t know if I am doing to much.
I have three other rooms to do and a amp closet so I would like to think I’m going in the right direction.

Hey man, could you share some specifics of how you designed and built that slat wall. I have a similar size wall that I am thinking of doing like that. What are sme of the other specifics that you did in the room? How does it sound, and what helped the most?

Thanks,
Jeremy

I first started by dry walling an insolating the whole room. The I cut out the space for the slats,
And removed the insulation. Then I sealed up the inside space and put back the insulation, and covered
Up the hole with fabric. I got the cheapest wood slats I could find 8-2 and 8- 3. Counter sunk for the screws , I had to put holes in the middle to keep from warping . Spaced the slats and put molding around
OH did I mention the free help!

So, there is nothing behind the slats other than air, space and the cement wall?

Interesting indeed, I would have though insulation or rockwool would have been required.

no I spelled insolation so bad my spell cheaker came up with isolation and I did not notice
There is owens corning acustic fiberglass behind the fabric
hope this clears that up

No problem, definately clears things up :) Thanks!
 
Well I guess I am going to make my slant walls fully absorptive and covered with cloth and then
Make a hanger where I can just place a 4-8 sheet of peg board or 4-8 sheet of thin maple.
That way I can treat the room any way I like. I am also going to please hangers on the slat wall.
Still open for ideas
Thank you

...what is the purpose of this slat wall?...

Broadband absorbtion.

From the SAE site:
"...The helmholtz resonator is often called a slat or slot resonator because you can create a helmholtz resonator by building a wall with slats of timber separated by slots...

The timber slats can be either finished or rough sawn. If the gaps vary say 5mm, 10mm, 15mm,20mm and the wall is angled as shown below, a broad band low mid absorber is created that still keeps the the high frequencies alive. Remember the cavity behind must be sealed to an airtight container, like the bottle.

Further more, our scientists have created a formula with which we can tune the resonator to a specific frequency. If we vary the depth from the wall, slat width, slot width (and the slat depth) we can create a wall that is a broadband low-mid frequency absorber. The beautiful thing about these absorbers is that they still reflect high frequencies, in fact they will diffuse them which is even better."
