Borderline

Hi All, I've a shot at buying a set of RP-3 towers but it appears I have two A speakers. By this I mean the Sub on both is located on the right side. Is this an issue I should worry about? Will having two A speakers have an adverse effect on anything? I don't know how in the world this happened but what do think the fair market price is for these missing the grills in OK condition? I would very much appreciate your knowledge on this matter. Thank You.
