Hi there,

I have a small room, aprox. 16m², and somehow where I used to listen was forming some boomy sound around 80hz.

After some tests, I changed the position of my sofa and I get some rich sound, but every other positions that I put my ears on causes boomy. When I say “every other positions” I mean 30cm above or sideways, in front… It’s really weird and I don’t know to treat that.

I tried to make tests with some mattress and helped, but of course was just a quick test.

You problably won’t understand nothing, but some pictures of my room yesterday on this brazilian forum: https://www.htforum.com/forum/…..st-7969807

Cheers
