Did I buy a counterfeit REL T5/i sub??


I recently purchased a used Rel T 5/i sub to go with the one I previously bought from an authorized dealer.  The used T 5/i had all the packaging, manuals, etc and the sub itself looks just like the one I have now.  This morning I noticed something different...the REL emblem on top of the sub and on the 4 legs is now written horizontally instead of diagonally.  Does anyone know if this was a recent official design change?  I doubt this sub is counterfeit but I will admit I have a little bit of doubt.  Please someone set my mind at ease....

Why not contact Rel and ask them if they changed logo placement?
Counterfeiting subs wouldn't be a very profitable venture, so I doubt it is.
Also, are the serial numbers very different for one another?-that would be another clue.

M&K claims counterfeit subs, among other things, drove them out of business. The factory in China that was making their subs was making more and selling them out the "back door" as it where. They were getting inquiries about a "piano black" sub, which they knew they never made.

So, it does happen.
