Changed room an the sound is not good, exept using room correction

Hey

I have changed room from big to small and the sound is not good. For the first time in my life i have to use room correction (Audyssy/Mcacc) then playing music.

Why is that?

Thanks in advance

Thanks for replying

Yes Onkyo and Pioneer.

The sound is like night and day with room correction on/off now. Before it was very small

Yes, but with different speakers:rolleyes:. But the same conclusion. Now the speakers sounds recessed and like haveing a blanket over them with room correction off
