Now, it occurs to me as well that if the VP-160 draws less power than both the VP-150 and VP-180 (4 ohm / 6 ohm vs. 8 ohm) and since the sensitivity is also good, that it will be less taxing on the amplifier, leaving more headroom for the rest of the system and for clean frequency response. Am I right on this?

But, now what about only 1 tweeter. Doesn't this mean it might not sound as good at loud volumes given it lacks the 2 tweeters of some of the other Axiom speakers?
