QUAD: Stacked Quads 57s in small room?

"For the last few years i have made do with a high end headphone system, but am moving in the next 2 months and will have my own music room so have decided im going to give speakers a go. I've never owned Hifi speakers before but after selling my headphone system i will have a decent amount to spend on Speakers / Amplifier.

I have been offered a paid of Stacked Quad 57's at a decent price and they sound perfect for me, i will be semi detached so dont need thunderous bass and am really trying to get "An Artist in the Room" experience. Prob is i've realised how big they are. I have quickly sketch out the following plan roughly to scale. What do you guys think."
