You don't want your center way high and your other speakers low, that will screw up the soundstage.
Really, why not? As I stated my center is hanging from my ceiling and I have never noticed anything screwy with my sound stage. Where I sit the tweets on my M80's are at ear level. My VP150 is aimed straight at my seating position, so all the sound waves are projected towards my ears. I guess it all sounds great since I sit in the sweet spot. But I've walked all over the room and I'm truely amazed by how great it all sounds no matter where I am in the room.
