If you are more into movies vs. music--YOU WANT/NEED A SUB(S).
Those DefTech built-in "subs" will not have the punch that you need for movies! For 2ch music, they will be fine.
For reference, I run the GE T2 in my HT rig (a newer cousin to the DT, same designer).....AND I have a Rythmik F15HP for the low end. Again, for music, I don't
need the sub (but I do like it and use it). But for movies, I
need the separate sub.
The other item to consider, the BP design means that these speakers will like need to be a foot or 2 further out into the room than you would need with a normal monopole design.
To be completely honest, if it were my $, I would be looking at brands other than DT (and, I do own a set of the older DT SM350 that will likely become my surrounds one day). But, if you are sold on DT, then scoop these up while they are cheap! 5 of these would set you back right around $1250 (or get 3 of these for the front, then a cheaper model for surrounds).

Then, add a subwoofer! This B-stock sub would get you right at your budget with 5x SM65
