Bipolar Surround Height?

[PaniqL]

After searching many topics regarding similar questions i have got too many mixed answers that it is hard to make a decision, i have 2 Klipsch RS-42 II speakers which are bipolar.

I would like to know what height to place them at, The general trend is 2-3FT above ear level but then many galleries and recommended placement diagrams tend to have floor standing speakers or speakers on stands about ear level.

I thought i should make a topic to get ideas that will be more specific to me and hopefully will get some helpful responses.

I will only be listening to movies or Games,
my bedroom is very small,
It will be a 5.1 setup so they will be behind me on the back wall,

I just wanted some opinions, if i am mainly listening to movies will having them quite high be effective?

If my room is small will it fill the room move with them being high?

Thanks
