Kicker CVRs: Old School or New?

[Genius16]

I am about to buy 2 15" Kicker CVRs. Which ones should I buy:

1. older gray ones with the black circle in the middle that says "Kicker CVR"

2. newer ones that are white with the red emblem in the middle.


The reason I ask is I have heard some people say the older version is better than the newer version . . . and of course some people say the newer version is better.

Which ones should I buy. I'm getting 2 15" in separate ported boxes.
