Oh I got an answer from Chet, when I emailed info@definitive 
The easiest way to tell between the ProSub 100 and 100TL is the low level LFE input. The 100 didn't have that (only had L/R RCA inputs). The 100TL has L/R & LFE as well.
I also found some .pdf review online (think it was an Australian publication) that showed the 100 had a 125W-rated amplifier, while the 100TL has a 250W amp in it.
The one I bought has the LFE on it so it looks like it's a 100TL
Also for more info on the older ProCinema series (including the 100TL and 200TL), see this marketing sheet from Definitive:
