Treating Corners

arthurs · « **on:** 29 Dec 2005, 04:46 pm »

When treating corners, which tend to be the corners needing more treatment in a typical room, the upper at the ceiling, the lower at the floor, or split the difference and treat halfway up the wall between the two? If forced to prioritize and do sequentially over time, where would you start? Thanks.

Art...

Check out this forum, where Ethan Winer resides. He is a great source for room treatments and information.

Arthurs,

All corners are equally important. The more you treat, the flatter and tighter the low end will be. Ideally you'd treat all 12 corners (!), though I understand this is not possible for most people.

Thanks Ethan, but if you had four corners and four 4' traps, where would you start until you could get to the rest? Thanks.

One in each corner would be the best (i.e., the four corners of a room).

Thanks Bob, I assume you mean the corners at the floor?

Corners at the floor and ceiling will react approximately the same. Either will be preferable to the middle of the wall where you'd miss the tri-corner where the wall/wall/ceiling junction is.

I meant at the wall-wall interface.

The tri-corners are the most important to start with. Regarding the vertical corners of the room versus the horizontal corners at the ceiling, it depends on what attributes are most important to you. Treating the ceiling corners will have a more pronounced effect on the reduction of echo and increasing overall clarity while the vertical corners will do more to widen and deepen your soundstage and produce a very natural midrange. Ethan is right of course though: "treat them all!"

Usually the ceiling tri-corner is much more effective because the floor corner's return wave is broken up by furnishing in the room, and often carpet. At the ceiling it's mostly a flat surface at all angles so the need is greater.

Agreed - if it is usable. Sometimes things like vaults, soffiting, vents, lights, etc. are in the way. My point was that either the floor/wall/wall tri-corner or the ceiling/wall/wall tri-corner were preferable to halfway up on the wall/wall corner where you'd miss both.

But what if you cut some of them?
