Sealed speakers.. wall reinforcement necessary?

The answer lies in the details and affected by many different things. I don't want to be pessimistic but if every closed box speaker user would describing their experience then we would be there where we started, but then we would have a pile of experiences with different rooms, speakers, positions, electronics and so on and nothing more.

What is your personal goal (if any) with this? Maybe someone can help you.
 
I had in past two pairs of Sequerra met 7.7 mk6 monitors and they liked to be close to the walls . I had them hanging directly from the walls with LINN brackets for home cinema and only 20cm to the wall .Real Sequerra sound was with the addition of the bass and ribbon tweeter.
