I understand the compromises of a horizontal centre and I have no doubt that the VP160 already blends quite well with M80's. However, the VP160 was specifically designed to sonically match the M60, which sounds different from the M80, so there must still be some room for adjustment in order to produce an even closer match to the M80.
I realize the VP180 already exists, and IMHO does match the M80 extremely well, but I'm thinking there is still a place for a "VP170" for M80 owners willing to sacrifice a tiny bit of max SPL and low frequency response in order to acheive slightly better off axis performance. I know, I know, by all accounts this mystical speaker has arrived in the VP160, but again, the VP160 cannot possibly match the M80 equally well if it was designed to match the M60.
