I feel like this topic likely already exists but am having trouble finding it in the forums.  

I have a new Arc and Sub. My wife strongly prefers the Arc to be wall mounted.  I am trying to decide if I should buy the Sonos branded wall mount which changes the power when wall mounted vs buying an off brand mount that does not make any adjustments to the sound of the Arc. 

My question is: Will the sub make up for any lost power of the mounted arc? will there be much of a difference in sound quality between a mounted Arc with Sub vs an unmounted Arc with Sub?
