Has anyone own or done a comparison of the centers?
Back last year, I traded in my VP160 for a VP180 essentially for aesthetics because I already had the M80s in the custom piano black and wanted the VP180 in the same finish. The trade-in value was essentially the same as what I paid so with the customize option sale that was going on at the time , I went ahead with the purchase.
Although, I couldn't make a direct comparison between the two, I would say that they are more similar than different even though the tweeter/mid-range configuration is different between the two which, in the case of the VP160, in my opinion, gives it a slight edge in "off axis" linear performance over the 180.
Either way, they are both large full-range models that would fit pretty much any speaker configuration and you couldn't go wrong with either of them.
