Looking at purchasing fronts and center (1 Viewer)

Hey everybody i am looking on purchasing two floorstanding front speakers and a matching center for my home theater. I have a 10inch JBL venue series sub and figured i would continue with the venue series speakers because they are exactly within my tight budget.
I was planning to buy the 3way arena floor speakers with a 6inch woofer along with the voice center channel. My question is should i go with the stadium floor speakers that have dual 8inch woofers instead and should i look into a different center?
I am a college student and as such this will be used primarily in smaller rooms, i use it for 90% movies, 10%music, but i want something that i can keep once i am out of college. Also i am not sure that having the sub will adequately cover the low end that the 8inchs would otherwise cross into.

Budget is tight but i want something worthwhile

I would go with the 8" driver if you can. On another note, why not check the auctions and consider piecing together a Studio L system. If you want to go with 6", take a look athe L880 and match it with an LC2. I like the LC1 however if youget the 880 and the LC2, you will have all identical drivers across the front. Plus, these are speaker that you can keep for a while if you tke care of them. Back to the other speakers, if you get the stadiums, consider the LC1.
