Bass traps? (to solve a suck out)

It is a while since I visited Realtraps website. There is a wealth of information here. I think Ethan does great service to audiophiles everywhere whether you buy his Realtraps or another acoustic company's products. I got GIK Tri-traps becuase I decided that the biggest thickest "superchunk" equivalents was what I needed most (of course I should have done much more if I wanted anytthing more than a very modest improvement but aesthetics will ultimately limit us all). Nevertheless, my choice to go with GIK did not stop me learning an awful lot from the material that Ethan has shared... you have to respect that!

i agree, i have some of his products now and i have spoken to him on a couple of different occasions. he is a nice guy and filled with loads of helpful information.

Do a search on A-gon for "superchunks"

If you're into DIY they do as much or most likely more (due to thickness) than any bass trap on the market

Now I'm really confused, not that that is an usual state of affairs. Can bass traps solve frequency response suckouts, or not? I maintain they can't. For those who maintain that bass traps are the solution, please estimate how large a trap would be necessary to deal with the 61Hz problem in the original question.

if you have a wide null centered at 61 Hz, your best bet is to try and cross a sub over a bit higher than 61 Hz and boost that null. just be careful not to create other issues with the added low freq energy released into the room. if you use a RTA while you are tweaking the sub settings to properly mate the sub to your main speakers, you can see the results with each turn of the knob. in the end, you will find this to be a very tedious process that can drive you insane.
