Movie soundtracks are mastered with a subwoofer in mind. Home theater really requires a sub because there are few, if any, tower speakers that can reproduce the lowest notes of a movie soundtrack. Much of the "punch" of the soundtrack in a movie comes from the sub (10-80Hz).
If I turn off my sub and set my RF-82 ii's to "Large" in my 4520, movies sound much different than they do with the sub in use - they lack the "punch" that is required for the sound to be immersive and the whole sound is much less engaging. The sub makes the difference.
Bottom line, you really need a sub. It also helps relieve some stress on your amp, since it will no longer need to drive your speakers below 80Hz.
