Before I spend over $1000-1500 on speakers for my new system, I just want to make sure what I am considering would work. I am hoping to have a 7.1 channel theater put in my basement. I have the receiver picked out, and am planning on going with in wall speakers (RC65i) on the back wall for the rear surround, in ceiling speakers (RC60 or 80i) for the middle surround speakers, and an in wall (SC-C) center channel speaker. I was hoping to use the 65T floor standing speakers for the left and right speakers. Would this setup work? That is, can I use RC series speakers mixed with an SC series center channel and floorstanding 65T speakers, or do I have to go with all RC series speakers? I am new to this, but want to make sure I don't buy a bunch of speakers that don't work well together.
Also, how necessary is it to have a subwoofer with this type of set up? I want the system to have great sound with the capability of blowing you away, but I also want to be able to watch TV and movies in the basement without waking up everyone in the house. Do subs have the option to be turned down and/or off if they are booming too loudly and shaking the house?
Sorry for the novice questions!
