Last minute treatment suggestions

[MindBender]

I have a few questions before i start mounting panels. The pic shows my initial plan. I'm almost done building panels so i want to start mounting them. The corner panels are 6' thick & the others are 4" thick.

1. Are the panels on the front wall necessary? I just watched one of Ethan's videos and he states that speakers mostly project the sound forward. Does that also include bass frequencies. I thought i read on another thread that the bass leaves the speakers from all directions. I'm using Event 20/20's with front port holes if that matters at all.

2. Ethan talks a lot about using as much bass trapping as possible. But does bass trapping pretty much ONLY occur in corners? If that's the case, do i need those panels in the middle of my front & rear wall? The distance from the mix position to the rear wall is obviously more than 10'.

3. With an angled ceiling, do i need a ceiling cloud?

4. Should I make the corner panels mid/high reflective? If so, can i use a plastic bag or something similar?

5. Regarding the mix position... If i can't have my ears right at 38% from the front wall, should I get as close to that as possible. In other words, is 33% better than 25%, or does it not matter at that point?


Any suggestions are greatly appreciated!!!

1. Maybe not. Part of tuning the room is trying different things and seeing what helps.

2. Bass trapping is more efficient in the corners. The traps in the middle are for broadband absorption.

3. Maybe not. (See 1)

4. Maybe. In a room that small I would just go for as much broadband absorption as possible.

5. 1/4 or 1/2 bad. Anything else better.

Thanks for your help Tex!

Looking good. Just needs one more panel...

You may want to do some live experimetning.

"Bass occuring in corners" isnt a matter of some physical attration, but rather that the diagonal from one corner to the opposite is the longest dimension in the room and thus that air column has the lowest resonant frequency.

But in this room you also have a very long and narrow air column in that hallway. I could definitly forsee that acting as a big resonator in whatever is the frequency of its wavelength You might need to do something above the transom of the door or on the door itself.

Panda read my mind. Kill that little bumpout and I think you're good as a first shot.

If you want more livliness in the back of the room, you can bag the rear corner absorbers and even the one centered on the rear wall since it's primary goal is killing the null off the back wall.

I'd definitely keep the panels on the front walls. As frequency goes lower, it starts projecting more like a sphere rather than just straight ahead.

If you can't sit at 38%, try 33%. Stay away from 40%. You may just have to play with it and see what the best you can get is that works realistically for you.
