Horizontal, Vertical, thicker?

A few questions about using a limited amount of panels.

I have 5 8'X4'X2" covered fibre-glass panels. My uncle gave them to me years ago from his office. I had no idea at the time how valuable they'd be for me one day.

So now, I'm just not sure how to use them. I'm lucky to have a pretty good, semi-dead, carpeted room. It's a pretty big room with a thick, cussion-y couch and a queen-sized bed, as well as desks, tables, etc...

I'm wondering if I'm better off mounting my panels horizontally to cover more wall side-to-side, or I should put them vertically so that they cover more frequencies in one space???

Also, why do people mount them? Isn't bass the biggest problem??? Or does furniture play a part in the decision to not have them touch the floor?

Last question: Should I worry more about doubling up the corners to absorb more bass, or is it better to have less in the corners to cover more wall elsewhere??

Sorry, I know that's alot of questions. Feel free to answer just one or more.

Thanx alot.

Yes, you want four inches thick when straddling corners for bass trapping. Two inches is okay elsewhere for mid and high frequencies.

yes...like ethan said, extra important that you double up in the corners. Vertical and Horizontal won't matter too much, you want to place the absorbers where they are going to catch the reflections.
 
But the real question is... what needs improving in your current room?

Presuming that it is bass buildup then doubling up four inches across two non-diagonal corners would be great. But it is a presumption that bass is the problem for your particular room.

So why don't you just experiment?
 
Not to be a stick in the mud but IMO, you'd get a lot more benefit if you turned them into a combination of 2" and 4" panels - 2'x4' rather than 4'x8'.

I didn't even recognize that he said 4'x8'.

Bpape is right...2'x4' is more efficient.
 
Yeah, never thought of that. They were office partitions, though, and the way they're put together makes them hard, if not impossible, to split up. I think there's a metal bar r something as a frame. They're covered in material, so maybe I can cut a little and see what the frame is made of.

But INNOVATIONS response was right on. I guess, while as a general rule, 4" in the corners is the way to go, it might not be the best way to go based on the limited amount of panels and the size of the room I'm working with. I'll experiment.

Thanx, guys. This is relatively new to me, and it's only after visiting this forum in the last few weeks that I realised room treatment isn't just a matter of throwing padding around.
 
Hi, Rami!

I supose that ,altough not treated with bass absorbers, your room, due to the big dimensions (and listening your mixes, ever sounds good), has not big problems with peaks and dips on bass frequencies, which is great.You know, If you can hear the bass drum and the bass as two separate instruments and identify subttle eq changes on both, half of a mix is ok... :) . But I´m sure the bass traps can improve the reverb decay time (happens with me), and it works like a cleaning on the whole mix (not only in the bass, ´cause 4" are broadband absorbers)
Anyway, as your ears are "trained" to your room, then, any change can seems strange in the first tests and mixes...

Why not place the panels on the back wall and first reflection points? Or use them as gobos? Then buy some fiberglass for the corners and cloud. Maybe need 10 4'x2'x2" batts of rigid fiberglass...
 
Gorty, that'a great article. I've skimmed through it before realising how important it all was. Now, I'm reading through word by word.

CIRO, I am lucky to have a pretty good room with no major reflections, so a little treatment should hopefully improve it even more.

Pandomonk, originally, I did what you suggested. But these things are heavy and a hassle to move around, so I want to try to find the best place to put them and leave them.
Thanx for all the advice, people.

That would still involve manual labor. :D

Well if you get some great movable gobos, isn't it worth the little bit of labor?
