Help....Again

Hey All,

Well i would like to get the help of u all once again as i have made some changes in my Going to be HT Room



Well my Room as planned will go with :

42" PLasma
Infocus N72 Projector
DENON 2808 Reciver
Dali Speakers IKON 2,6, Vocal2
XBOX 360
TATA SKY
TV Screen


And now i am going with a glass wall on the back wall of the sitting area & in front of The TV ... So i am bit confussed what to do with the Speaker position of the Back speakers as the back wall is of glass..... So please help me out...

and also please mention is it necessary to get an voltage stablizer..... as the voltage stablizer makes lot of noise and so we cant keep it in the HT Room... and if i have to keep it in another room... there will be a lot of wiring works... and there wont be any space to keep the Stablizer as it will make the look of the other room bad.....
