'I need to place the speakers very close to the back wall so i was considering closed cabinet design.'
Depends upon what you mean by 'very close'.
Almost every speaker I've had was designed to placed close to or up against the wall. Every single one of them benefitted from a couple of inches of space between them and the wall.
Even the 2 Rega bookshelf models began to harden up a touch when pushed up right against the wall - and they were designed to be placed against the wall!
I think it depends upon the design and the boundary reflections.
As far as I know, there aren't many large speakers that don't need ample room (12-18 inches min) behind them.
My Tannoy Berkeley's need more than the 6 - 8 inches currently behind them for optimum performance so I probably only get around 90% performance from them. Unless I got some wheeled stands that's the best my domestic circumstances will allow.
In any case, at this level you should still make sure the sound fits you first and then the room - and not the other way around. I wouldn't be too surprised if the 3 that you mention all sound quite different, and you might have a strong preference for one over the others.
