Can I put a 60" tv behind my Magnepan 3.7i speakers?

I'm having trouble thinking this through...my listening room has 3  sides with records 7 rows high... Concrete floor, but all  carpeted the speakers are 5' from the wall    Definitely not a lively room! I was thinking about putting a new 60 inch tv between and behind them...apparently the tv with base would be around 14" off the wall( I could bring the speakers out another 10" if 'necessary')
any guess how it might affect the sound and imaging etc???
THANKS!
