I am getting ready to move into a home and I am going to have a dedicated Home Theater room built in the basement. I have plenty of questions and any help you can offer is greatly appreciated. Current equipment consist of an Hitachi Elite 65” HDTV (will eventually be replaced with a front projection unit), Pioneer Elite 45TX 7.1 Channel receiver, Front speakers are PSB Image 5T, Center speaker is PSB Image C9. Sub woofer is Kenwood can't remember the model and it will eventually be replaced. I need to pick up some new surrounds now and I was thinking of getting PSB Image S50’s for the side surrounds and B15 for the back surrounds. Is this a good speaker setup for new surrounds or would you recommend a different combination? Room size: The width will be Approx 13’. I was going to make the depth of the room 20’ but I can decrease this if needed, height is 9’. Is a 13’ by 20’ room good or should my depth be smaller? I was thinking of putting the 2 rows of seating at about 10’ and 13’ from the screen which will be framed into the wall. Speaker placement: I was thinking of framing my front and center speakers into the wall. I will not be enclosing the speakers. Will the backs of the speakers not being in the room effect the sound? On the side surrounds I am planning on placing them between the two rows of seating. Is it ok to ceiling mount these or should I wall mount them or put them on a stand? For the Rear surrounds if my seating is at 10 and 13 ft from the front and my depth is 20’ how far back should they be? Should these be mounted or put on stands?
