Bad choice of words on my part. I meant in relation to the VP180 not the M80. As you say, there simply is no substitute for a third M80 for centre.
The frequency graphs show the VP180 still tracking a bit flatter than the vP160, which has a baby bump around 70-150Hz. If they could come out with another centre that sounds even closer to the VP180 (without the same max SPL or low freq abilities of course) but with the off axis of a VP160, then that would be the cat's meow. Either way, the VP160 has gotten me so curious I may have try one out.
