I use my system for 70% movies, 20% music dvd, and 10% audio cd's. I have a smaller room with about 100 watts per channel (8 ohm rating) to throw at them. Wht do you guys think?Well, conventional wisdom would suggest that you would go with floor standers because of your 70% movie preference. However, the fact that you said you have a "smaller" room may mean that you may be better served with a pair of quality bookshelf speakers that can reach down to around 50hz before obvious roll off.
Floor standers require ample space to perform at their best. If your room is as small as you say it is (please provide room dimensions) then floor standers may hurt your over all listening experience more than help. Besides the obvious increase in dynamics and impact that floor standers bring, it won't mean anything if the bass is muddy and slow due to improper placement and room size restrictions.
In addition, bookshelf provide a higher level of focus, air and imaging in smaller places. The lack of dynamics that most associate with bookshelf speakers only really comes into play at higher volume levels and in your "smaller" room would most likely not come into play unless you like to play your music at party levels.
