How much better than the VP150? Good question, the VP150 is a good center for what it was originally designed for but the VP160 is a FULL range center with good off axis response. I could say it is like comparing the M22 to the M60 or M80, the M22 is a great speaker but it isn't up to the same level as the floorstanders, the 160 is worth the $100 more to buy, but this is also just my opinion, YMMV.
