thanks for all replies guys
just keep in mind this is only hobby studio and i want to improve my mixes.
i know that i never be able to master like a pro i my bedroom but i was wonderig what i could to just to make it better. Acoustic foam is pretty affordable and if can use it that would be awesome.
What about foam bass absorbers? can i use them?
I came across this tip for acoustic foam:
When treating the front and side walls, try using a mirror to ascertain where reflections are coming from. Simply have a friend move a mirror around the walls and ceiling while you are sitting at the mix position. Anywhere you can see your studio monitors in the reflection is a likely surface to treat with an Studio foam panel
what do you think?
and i the future i would like to ad active sub to my Behringer Thruth's good idea?
thanks for reading and all your help
my studio jpg. files should be attached
