Was about to pull the trigger on the LS50s, but I've seen some comments regarding placement and so wondering if it would be an issue if these are going to be placed in the corners of my room? I see in the manual they recommend that they are roughly 20" from the walls (or you put something in the port if they are closer), but that won't pass the WAF test, so realistically they'll be in the corners of the room. Is that going to be an issue?
