The VP150 can keep upto the M80s to an extent, but for sheer volume it can't compete and this is what I believe that reviewer was talking about, the center became lost, to him, during loud passages. I think it was more a matter of it blended in too well and he lost where it was, a sign of a good center, IMO.
The 60s are a very good speaker and I actually prefer their look to the M80s full face grille, even without the grille, I still like the look of that extra bit of wood showing below the drivers.
