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

@geoffkait I am not sure I understand what you are suggesting. I measured my room response only from my listening position so isnt this where the wave is?

The wave at your listening position is determined to a large extent by the other waves in the room, waves like reflected waves, standing waves in room corners, standing waves anywhere in the 3D space. Waves interact. It's quite possible to be sitting right in the middle of a standing wave.

I had great success with room equalization and did it all in the analog realm without spending much money.  I had a major issue with boomy bass in a small room last year.  I got an XTZ room analyzer Pro and it identified a big room mode at 38hz, suggesting a -22db correction. I attenuated it down about 15db with a McIntosh MQ 107 equalizer and the boomy bass issue was completely gone. One of the most immediate and dramatic changes to my system ever.  I think the digital room EQ devices work well too but the analog equalizer I got is from the 1980s and was very inexpensive.  Would be worth a try. 

Contact GIK acoustics for help, and you may need to place your speakers like they were 2 subs.  What I mean is, you may need to place 1 speaker, and then look for the best location for the second. Use a mic to find the locations that have the worst nulls and try to put the second speaker there. :)

Best,

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.

Thank you guys for the reply.  

This weekend I did some experiments with some extra GIK panels I had.. I put a 244 panel on the ground next to the speaker, a 244 on a Softfit bass trap at the first reflection point, and the Softfit was laid horizontally on the ground against the side wall at the midpoint. The interesting thing is I got better results with just the two 244 panels (removing the SoftFit on the ground) except for a deep null at 160hz which the Softfit on the ground seemed to do a much better job improving it by over 11db! I am wondering if using Monster Traps on the side would be better instead of my 244s and the Softfit on the ground.  I guess only one way to find out and buy some!
