Equipment Location at First Reflection Point

A recent discussion on speaker positioning also had comments about where to place equipment.  Due to multiple door/window/furniture constraints,  the only configuration that works is to place the equipment on the right side wall.  However, to avoid bass modes the only location on the sidewall is at the first reflection point.  I've searched the forums for comments about this (as well as Smith's book) and found nothing that addresses whether or not this is a problem.  Just wondering whether this is an issue and, if so, how would you address it ?
