Reflections off a tile wall?

[Wolfy]

Hi all, I think I may have identified a problem that has been bugging me about my system for a while. Ever since I got my new energy speakers that is. It's been since Christmas. My right speaker is next to some tile on the wall for a fireplace and I think it is causing some "audio anomalies"- we'll call them that for now. I can post some pics tomorrow when there is sufficient light, but let's just say I can't put the speaker anywhere else. I only hear these anomalies from the right speaker. (and I switched speakers left to right and didn't see much difference) It is a kind of static which I mentioned in my other thread labeled "clipping receiver?". It could be reflections coming from that tile wall. I noticed when the speaker is between me and the wall I hear this sound in certain situations, and when I am between the speaker and the wall I don't hear it. However, this is all speculation as to what the problem is. So what can I put up temporarily at first and then maybe move to some acoustic tile later? Would a blanket work? Maybe just a towel? If I do this and it goes away, I will be one happy camper and will shell out a reasonable amount for something like the acoustic tile if that is what it needs. Any advice here would be welcomed. Thanks for reading my long post.
