Hi i am thinking to go 7.1 but the problem is in my bedroom my bed is against the back wall and cant be moved. so can i put the rears on the side of the bed in stands and surround back high up on the back wall pointing towards my head? or can i connect 4 speakers on the back wall eg: to furthest are rear speakers pointing towards me and 2 surround back speakers higher up pointing downwards? would this work? or in my situation shall i go for front height speakers? but if i choose this option can i get the best out of 7.1 blurays?
