Hey.
My 240ti`s has no serie nr back badge. I would like to put these in the serial nr list but...
Was there orginally any?

Cant see any tech logo at http://manuals.harman.com/JBL/HOM/Technical%20Sheet/240Ti%20ts.pdf

Cant see any for the 250ti either. But i remember there was a tech logo at the back of the 250ti...i think.

Anyone bother to take a look at their 240ti`s?

The serial numbers on my 120Tis are right above the speaker connectors, as shown here:

I'd assume the 240TIs are similar. The numbers is printed on a sticker, something I've always wondered about (being something too easily replicated/falsified). Maybe the number is also stamped somewhere inside the cabinet too, I don't know.
