Any changes in LSi15 over last 2 years

[bbeacham]

I am going to upgrade my rear LSi7s to LSi15s (same as front). I was wondering if Polk has tweaked the speakers in the last 2 years so that I should put the new LSi15s in the front, and the old ones in the rear.

Haven't heard of any known updates, since the redesign of the finish almost 5 yrs ago? I'm sure CS can give you the true answer, I'm almost positive there is none.
