Corner-Cube Bass Trap Idea... What do you think?

[hduncan]

I have been trying to figure out the best, most aesthetically pleasing way to design/place a trap in the all-important Tri-Corners. From what I gather, more bass sound focuses in the wall/wall/floor and wall/wall/ceiling corners than any other corners in a room.

Here is something I came up with using little pieces of paper, some tape, and some spare time.



The Cube Trap would be a 2'x2'x2' Cube made by stacking 2'x2' fiberglass squares on top of each other.

Of course, I haven't really received a definitive answer as to whether the Tri-Corners focus more bass (and thus, have more potential bass trapping rewards) than any other corners.

Ethan/James/Glenn, would a room benefit from having one of these Cube Traps placed Specifically in the Tri-Corners versus any other location? Or are the Tri-Corners no more bass-focusing than any other corner?

Either way- At least this Cube Trap solves an aesthetic problem in that it allows all three corner traps to meet consistently.

I'm sure this will work well if it's large enough, though I'm not sure why you posted here instead of the Bass Traps section.

I was thinking about it more from an aesthetic perspective, I guess. But you're right, the bass traps thread seems like a much better home.

Can we get it moved, please?

Oh yeah, Ethan, is the Tri-Corner bit true? If you could only trap 4 places in a room for bass improvment, would the Tri Corners be top priority?

Hard to say, and size is key. A 4-inch trap in a tri-corner will not be as good as a 2x4 foot panel in a wall-wall corner. So then, how far away does the tri-corner trap extend down the other corners?

Assuming we are using the 2'x2'x4" MiniTrap. Would it perform better while straddling a corner or laying across a Tri-Corner like in your theater room with the puppets ?



Or- another example would be, if I build this 2'x2'x2' Cube Trap. Would it be more efficient the way my little paper model shows, wedged into the Tri-Corner, or would it be better performing if it were at the halfway point between floor and ceiling, wedged into the Wall-Wall corner?

[hduncan]

I can't find an answer anywhere. Are Tri-Corners the top priority when beginning to trap for bass?

I don't want to waste material building my cube trap if it wont outperform a simple 4" panel in the wall/wall corner

[Ethan Winer]

If you're making your own traps, just fill the entire corner from floor to ceiling. However you do that is fine, as long as the trap is thick and large.

Hey Ethan. I was trying to maximize absorption/cost efficiency. It would cost significantly more to do the whole corner superchunk concept..

My line of thinking was that, if the Tri-Corners focus more bass, maybe I should spend the extra cash to treat them... but if the Wall/Wall/Floor corner has just as much potential benefit from trapping as the middle of the Wall/Wall corner, then I wont bother with my Cube Trap...

However, It seems logical to me that the Tri-Corners would have more focusing of bass...

[Ethan Winer]

The only way to know what's best is to measure the room's LF response at high resolution with the traps in different places.

--Ethan

[hduncan]

Ah, so there is no evidence or theory to support the idea that more bass focuses in the Tri-Corners... That's ok..

Maybe I won't bother with the cube idea and I'll just stick to the standard 2'x4'x4" traps.

I could have sworn I heard a credible source say that the Tri-Corners were the most important corners to trap for bass.. Guess not.

Thanks Everyone

Yes, tri-corners DO collect bass! But so do all other corners. And the front and back walls too.

Hey Ethan, what I am trying to figure out is if a Tri-Corner deserves more bass-trapping than a Bi-Corner. What's your advice?

Should I bother giving special attention to the Tri-Corners with this solid Cube trap? (with regular panels everywhere else) or should I just use the 2'x4' panels everywhere?

[johndykstra]

surface area is the key...and airspace behind the trap yeilds a more efficient design. a solid block in the corner is not as effecient as a panel covering said corner. should you treat the "tri-corner"...absolutetly possibly....constructing multi-purpose rectangular traps that can be "auditioned" in multiple places is your best bet. if you have a trap straddleing a wall/wall corner, from floor to ceiling, you are in effect treating the tri-corners.

In theory the tri corners will pick up more bass.

You can give special attention to them, but really it is more about covering more area throughout the room. Honestly if you cover tri corners, measure then move the panels out of the tri corner to wall to wall corner, then measure again you will see a difference but not sure you would HEAR the difference.

that second sentence seems counterintuitive. if the exposed surface areas are equal (iow, the faces of two traps are the same), how could the one with air behind it be more efficient than one that is solid all the way? i'm thinking here of triangle shaped traps with the hypotenuse facing out, so it looks the same in the room as a panel straddling the corner.

in that case the triangle has way more surface area (and overall mass) but no airspace. you're saying the panel is more efficient? is there data to support this?

thanks.

I'm not the one to quote data...as I am certainly no expert. But it's been my understanding that air space behind bass traps is effecient. And in saying effecient, purhaps I should have said cost effective. As in, the return on investment of filling a corner completely is not equal to the efficiency of using the same amount of insulation to straddle more area.

Glenn or Ethan please correct me if I'm wrong.
