Hmmm. I just looked in the Yamaha manual and there does seem to be some kind of Center Graphic Equalizer.

Yup... I've got my centre (a good scratch built one from my last kick at home audio just out of high school) - it's two 4.5" poly woofers and a 3/4" dome tweeter. It's pretty nasal compared to the Axioms, so I've got a slight EQ on it. Not the best solution, but until I pick the lock on my wallet and order a VP100...
