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!

There are also room resonance calculators/simulators on the 'net. You put your room dimensions into a form, and a three dimensional depiction of where standing waves are produced in the room will be displayed. That is where bass traps should go. An active electronic unit designed to deal with the problem, like the DSPeaker Anti-Mode 2.0 Dual Core, can also be of help.
tboooe, the reason eq doesn't help with the dips is because they are "nulls", the rooms dimensions creating frequency cancellations that no amount of eq can correct for---an infinitely deep hole at null frequencies. The only way to deal with nulls is to move the speakers around, the find a location where the nulls are shallowest.
