Proac Rake angle?

With the D48r, and my current listening chair, with the speakers perfectly level, my ear is at the top of the surround of the top woofer, instead of tweeter level.  I'm assuming that this is not allowing me to get the best tone and image out of these speakers.  I have some outriggers on the way that will allow me to adjust the rake angle more easily.  But I'm not sure if tilting this speaker back to get the tweeter to fire my ear will actually be completely beneficial.  Would this skew the crossover alignment?  Would I be better off trying to find a chair to get lower? Any experience?
