The corners of any room are where most sound waves end up at a certain point. If you need to reduce reverberation this is great location to place your absorbents. An absorbent panel placed in a corner will be 95% as efficient as a triangle bass traps made of the same material.
You are the only person who can judge if you like the sound of a given space. Some times we want a very dry room other times we like to record in a big cathedral.
