Help with a search

Hello,

I've just built a new pair of ML TL speakers based on MJK's worksheets.
So far good (not finished yet), -3dB @40Hz measured .

Now, it's exciting a room mode at some 30~40Hz and I need to tame it

I tried a search for damping tube and tube to no avail.

Any help on search terms is highly appreciated.

Thanks,

Give "bass trap" and "room treatment" a try.
