For those who are pumping huge amounts of power into their centre and are concerned about dynamic compression below some frequency. Axiom has never defined "huge" nor the frequency. When crossing over at 80Hz, you absolutely don't need an HP driver. But for anyone crossing over at 40Hz, they might want to check with Axiom.
I tried crossing over below 60hz on all three front speakers and seem like you are losing a lot dynamic bass on scene like big explosion. Crossing over at 80hz for all speaker sound best. I find the HP benefits from running 2 channels full range for music, makes the speaker sound very good but I find it a bit too boomy. Still unsure why axiom offers the HP for the Center. 3 channel music?
