Could I damage my woofers by trying this?

I have a pair of upgraded OHM I's. It has 5 drivers. 3 on top pointing up and 2 on the front. For a differnt sound Im wanting to change their postion. That is, their vertical position. I want to turn them down about 30 degrees where the 3 drivers are aimed at me. Since the woofer will be closer to the floor, could I damage them? Will the woofer be able to breathe? The speaker has 2 vents on the front. I am always tweaking. Your input would be appreciated. Mike
