Help with LCR design and Components

[wishucould00]

I am fairly new to the DIY home theater scene but as you can see I've dipped my toes and build my first subwoofer enclosure (not veneered yet). Now I need assistance with building a LCR. I don't have space for floor standing speakers so what i wanted to do was build something that I can either mount to the wall or place on top of a shelf. My plan is to build a shelf across the wall thats about the same height as the bottom shelf of the fireplace. I was thinking of buying Def Tech XLR50's but I'd really like to build something. So basically what i need to know is what size enclosure I could get away with using 4 speakers and 1 tweeter per side. Thanks again for any and all help.

Ok off the shelf on walls it is :/

That close to the wall is about the worst setup for sound quality, do you need to do that? You say you don't have room for floorstanders yet you have them there now. What exactly are you trying to do here? REplace your Klipsch with something else?
