My opinion is not to have speakers behind a screen. I did some research here and found that you will sacrfice picture quality and sound quality. As tempting as it is to do it this way.
I love the look of the W series. The are very clean and you can make them blend with your decor. The only problem I see with them is that you can't angle them or move them. Once you place them you are pretty much stuck.
I have a 136 inch screen and here is how I set up mine only with the M80's, EP500 and VP150. It sounds great and at the same time I have some flex. on speaker placement Tweaking.
