I agree with Randy. I find that I like more the way my system sounds when crossed over at 40Hz rather than 80Hz. If the towers are to be crossed at 80Hz, it should be little difference with the 22s, but if crossed lower, I find also to have more impact from the mid bass punch.
Either or not this small difference is worth the price tag is a different story.
