I think I need more bass traps, where to place them??


Hi guys, I already have bass traps in all four corners of my room but I still have some pretty bad room modes resulting in big peaks at 60/120hz and dips at 80/160hz.

I spent hours and days messing around with speaker placement and my current setup is the best I can do in terms of matching my target room response curve aside from these modes.

So my question is...I assume I need more bass traps?  If so, what is next logical position for them?  Sidewalls?  Front wall between the speakers or directly behind speakers?  Back wall?  If the answer is yes to all positions, then where should I start?  Due to financial restrictions I would like to treat one area at a time.

Thank you!

Remember the soffits can be hung up where the walls meet the ceilings as well. :)

Reflection points don't work all that much for < 100 Hz where the worst issues will occur.

Also, with enough bass traps, EQ can become effective with nulls. :)
Thank you @erik_squires What I am realizing (at least in my room), is the floor to wall interaction has a bigger impact in terms of bass than the vertical room corners as is traditionally mentioned. I am thinking about getting the 12" x 48" Monster Bass Trap and laying that horizontally on the floor. Then placing my 244 panel on it so it is at the appropriate height to deal with the reflections.

Based on what I am hearing, I will definitely need to think about adding some traps at the ceiling/wall corners too. One small issue for me is that I have crown molding so I need to find a way around that.
I'd ask GIK For advice. :)

But soffit traps ton't have to be exactly in the corners to work. With museum hangars, you may even be able to use the crown moldings to hang the traps from.  They're like S hooks which slide above the moulding. Depends on exactly what kind of moulding. :)
