Does it have any good effects if I tilted my bass trap which is hanging on the ceiling slightly at an angle?
I just thought aesthetically it would look nicer but I am not sure what effects will it have on my acoustics.
...angling absorption panels really doesn't add any benefit, and can actually make the absorption characteristics of the panel less predictable.
Not sure if that applies to specific types...but something like the Real Traps type are often shown angled across the ceiling/wall corners...and I think Ethan recommends them to be hung that way in that area....
...though I often wondered if NOT angling them across the corner, but instead hanging them parallel to the ceiling (but still close to the corner) would somehow take away from their corner bass trapping efficiency...?
No, you're right there...angling them across a corner is a different thing though. I think the OP is talking about just angling them when they're placed flat to avoid parallel surfaces.
btw if I was the build my own bass traps whats the best way to build it and really make use of it?
I see most ppl just build liek a wooden frame and stick insulation in and wrap it around with fabric....
is that really the way?
